A show cave with no guide. You walk the one-kilometre route yourself, at your own pace, up 297 steps and 87 m of ascent into the Niederhorn massif, with the cave stream and its underground waterfalls beside you the whole way. CHF 20 covers the cave, the cave museum and an app guide in English, German and French. Since November 2025 the caves have been open all year for the first time – with one gap: in 2026 they close for maintenance from 9 to 20 November, which almost nothing written in English mentions.

Tickets and prices
There are no time slots, no allocations and no advance booking to worry about. You buy at the ticket desk by the cave entrance and walk in. The operator sells online tickets and gift vouchers through its own shop, but they save you a queue, not a journey.

When everything is sold out
The cave cannot sell out. The car park can. The operator runs a banner across every page of its site saying there are not enough spaces for all its guests and asking people to come by public transport.
Tickets and tours for the St Beatus Caves
Worth saying plainly: the entry ticket with the cave museum starts at $24.32 on GetYourGuide, and the same ticket at the desk costs CHF 20, which is about $24.22 at the ECB rate of 18 September 2026. You are not saving money. What you buy is the admin – it is the most booked offer here, with 358 reviews, and it puts the ticket on your phone before you climb the footpath. The two other options are transfers rather than bargains: a tour from Interlaken with hotel pickup from $229 and one from Zurich from $607. They earn their keep only if you genuinely need the driving, the timing and a guide taken off your hands. Otherwise bus 21 reaches the caves in 13 minutes from Interlaken West, and the BLS boat combined ticket from Interlaken West costs from CHF 30.40 for the return crossing plus entry and museum – it halves the admission. If you are making your own way, buy where the discount is: with the boat, with SBB RailAway (20 per cent) or on the Berner Oberland Pass (30 per cent). The Swiss Travel Pass covers the journey but not the cave.

Opening hours and best time
Summer season 2026: 28 March to 8 November. The caves open Monday to Thursday and Sunday 9am–6pm, last entry 5.15pm; Friday and Saturday 9am–9pm, last entry 8.15pm. Winter season: 21 November 2026 to 20 March 2027, Monday to Friday and Sunday 10am–5pm, last entry 4.15pm; Saturday 10am–6.30pm, last entry 5.45pm. Between the two seasons the site shuts for maintenance: 9 to 20 November 2026. The cave museum keeps shorter hours than the caves – daily 10.30am–6pm in summer, daily noon–5.30pm in winter – so an early arrival means the caves first and the museum afterwards. The Stein & Sein restaurant runs Mon–Thu and Sun 9am–6pm and Fri–Sat 9am–10pm in summer; in winter Mon–Fri 10am–5pm, Sat 10am–9pm, Sun 9.30am–5pm.
When it is quietest
A weekday, early morning or late afternoon. Because everyone walks out and back on the same path, a coach party makes itself felt. Friday and Saturday evenings are the quietest slot of all, and in summer they are the only times the caves stay open until 9pm, with last entry at 8.15pm. The waterfall at the entrance is at its most violent in heavy rain and during the spring snowmelt. Inside, the weather is irrelevant: 8–10 °C all year. That makes this the most dependable wet-weather and heatwave fallback in the Interlaken area, and a sensible rest-day option if you are skiing at Grindelwald or Wengen. Winter is now a genuine choice rather than a closed door: the cooperative deliberately markets the quiet months with fondue evenings, raclette in the grotto and candlelit cave tours.
Who it suits
With children
The operator suggests roughly age five or six upwards. In its favour: nobody has to stand still in a group. Against it: 297 steps. Outside there is the Flimboweg, an interactive trail with four hands-on stations that takes about an hour, a playground with a dragon slide and a public fire pit; the operator reckons on three to five hours for a full family day.
Minimum age
None. The family card covers children aged 6 to 16; younger children are free.
Wheelchair
No. Narrow passages and 297 steps rule out wheelchairs. The museum and the restaurant are step-free, but only if you approach from the lower car park P1.
Pushchair
Not inside. The surfaced path up from the car park takes a pushchair; the cave does not. Bring a carrier for small children.
Dogs
Dogs are allowed, for CHF 10 ($12.11). That is unusual – most European show caves refuse them outright.
Claustrophobia
The route is a kilometre of built, lit, railed walkway, but it is narrow, you meet everyone coming the other way, and in places the ceiling is low enough that tall visitors have to duck. There is nothing here on the scale of the great chambers at Postojna or Škocjan.
What to wear
A constant 8–10 °C (46–50 °F) at about 95 per cent humidity: take a jacket or fleece even in August. The walkway and steps are wet, so shoes with grip – you will want them for the climb up past the waterfall as well.
Photography
Photography is allowed and encouraged. Tripods have to be left at the ticket desk so they do not block the walkway. Eating, drinking and smoking are not permitted inside the cave.
Getting there
By public transport
STI bus 21 runs between Interlaken and Thun and stops at "Beatushöhlen", right by the site. The route timetable valid from 14 December 2025 gives 13 minutes from Interlaken West station and about 40 minutes from Thun station. By boat, BLS services call at "Beatushöhlen-Sundlauenen" on the lake; from the landing stage it is a 20 to 25 minute walk uphill, appreciably more than from the car park, and boat services thin out badly in the low season, so check the timetable before you rely on them. Cyclists can ride the Lake Thun cycle route; there are e-bike and mountain bike racks on site.
By car
Two paid car parks below the caves: the lower P1 and the upper P2 by the museum. A day ticket costs CHF 7 ($8.48) for up to 24 hours. From the car park it is 5 to 10 minutes on foot to the cave entrance along a well-built, surfaced path that crosses the Beatus waterfall on bridges and walkways. The operator warns on every page that spaces fill quickly in high season and at weekends. The lakeside road on the north shore is narrow, twisting and full of tunnels, and traffic backs up when a bus comes the other way.
From the nearest city
About 17 km from Thun, the figure the operator gives. Bus 21 takes 13 minutes from Interlaken West and about 40 from Thun. On foot: 60 to 70 minutes from Beatenbucht along the shore path, 75 to 90 minutes from Merligen – the caves sit directly on the Via Jacobi pilgrim route. Walking out from Interlaken along the lake takes roughly two to two and a half hours.
Tips for your visit
- Come by boat if you want the cheapest day out. The BLS combined ticket halves the admission and costs from CHF 30.40 ($36.82) from Interlaken West for the return trip plus cave and museum – admission alone would be CHF 20.
- If you drive, arrive early. The operator says outright that there are not enough spaces, and there is almost nowhere to wait for one. Roll up at 11am on a summer Saturday and you will be circling.
- From the boat landing it is 20 to 25 minutes steeply uphill; from the car park only 5 to 10. Factor that in if anyone in the party walks slowly – the climb to the entrance is harder work than the cave itself.
- Take a jacket, whatever the forecast. An hour of slow walking at 8–10 °C and 95 per cent humidity feels colder than the number suggests.
- Use the Friday or Saturday evening opening. It is the only time the caves stay open to 9pm in summer, and the quietest stretch of the week.
- Do the cave first if you arrive at opening. The museum does not open until 10.30am in summer and noon in winter, while the caves open at 9am and 10am respectively.
- You can visit the site without paying at all. The waterfall path, the Flimboweg, the playground and the fire pit are free; only the cave is ticketed.
- Dogs are welcome for CHF 10, but nothing else is relaxed inside: no eating, drinking or smoking, and tripods stay at the ticket desk.
What the internet gets wrong
There is no seasonal pricing at St Beatus and has not been for years. One flat rate applies all year: CHF 20 for adults, CHF 12 for children 6 to 16, free under six, CHF 52 for the family card.
The caves have run year-round since 10 November 2025. In 2026 the only closure is the maintenance break from 9 to 20 November; the winter season then runs from 21 November 2026 to 20 March 2027.
True once, wrong now. Winter weekend-only opening began in November 2022 and ended on 1 February 2025, since when the caves have opened daily in winter as well.
"Adults have to pay about 19 CHF to visit the cave itself, and the guided tour is included in this price" (arzotravels.com); "Cave tours can be self-guided or with an English-speaking guide at no extra cost. Tours last 75 minutes and depart approximately every 45 minutes" (thebudgetmindedtraveler.com); "Guided tours depart every 45 minutes" (triphobo.com); "Guided tours leave every 30 minutes" (swissfamilyfun.com). There is no scheduled guided tour for individual visitors and no free guide. What the CHF 20 ticket includes is an app guide in English, German and French. Guided tours are bookable group experiences costing CHF 30 to CHF 65 per person, with minimum group sizes of 10 or 20 and a minimum charge of CHF 600 to CHF 980.
The operator gives the visitor route as one kilometre, with 297 steps and 87 m of ascent, walked out and back.
A page frozen a decade ago and still ranking. Summer hours are 9am–6pm, until 9pm on Fridays and Saturdays; the restaurant has been called Stein & Sein since 2022.
Bus 21 covers the distance from Interlaken West in 13 minutes, and the lakeside walk from town takes about two to two and a half hours. Nineteen kilometres is roughly the figure for Thun, which the operator puts at 17 km.
The operator says 20 to 25 minutes uphill, in both its German and English pages. A small difference, but it is the number people use to decide whether they can make the next boat back.
the earliest vitae are 10th- and 11th-century and have never been historically authenticated.
closed 9 to 20 November 2026.
History in brief
- The operator dates human use of the grottoes in the Beatenberg cliff to the Hallstatt period, 750 to 450 BC, when they served as refuges.
- By legend, the Irish-Scottish missionary Beatus drove a fire-breathing dragon out of the cave and set up his hermitage beside it; the dragon plunged into Lake Thun. His grave and a reconstruction of his cell can still be seen at the entrance.
- None of that is documented history. The earliest surviving accounts of Beatus date from no earlier than the 10th and mid-11th centuries and have never been authenticated; the figure has been conflated with other saints of the same name, above all Beatus of Vendôme. The hermitage, if it existed, is placed around the ninth century, not the second.
- Until the Reformation a pilgrimage chapel dedicated to the saint stood in the cave, under the authority of the monastery at Interlaken.
- In 1528 the Bernese government had the chapel torn down and the cave mouth walled up to stop the pilgrimages. Catholics from Unterwalden broke the wall open again, and the cycle of walling up and breaking through repeated itself. As a counterweight, Bern built a Reformed church on the Beatenberg in 1534–1535.
- In 1814 the painter Hans Stähli made the first documented push into the mountain, about 200 m. In 1848 Johannes Knechtenhofer, the first steamer captain on Lake Thun, got roughly 20 m further; the Kapitänsgrotte, the Captain's Grotto, is named after him.
- On Maundy Thursday 1903 Hermann Hartmann, head of the Bernese Oberland tourist association, and Gottfried Bühler explored the system properly. A "Beatus commission" was formed, a path was built up from the main road and the front sections of the cave were made safe.
- The Beatushöhlen-Genossenschaft was founded on 24 April 1904 and the caves have been open to visitors ever since. The same cooperative still runs them.
- The Stein & Sein restaurant opened in 2022, the same year the caves first opened in winter – on Saturdays and Sundays only, with the main season still running April to October. From 1 February 2025 they opened daily in winter too, and since 10 November 2025 they have run continuously all year apart from maintenance days.
- In 2025 the cooperative counted about 196,000 visitors, up 9.8 per cent and the best result in its history. The figure was 178,570 in 2024 and 114,523 in 2022.
Frequent questions
How much does it cost to visit the St Beatus Caves in 2026?
CHF 20 for adults (about $24.22), CHF 12 for children aged 6 to 16, free for under-sixes. The family card, covering up to two adults and their own children, is CHF 52, and a dog is CHF 10. The rate is the same all year – there is no high-season or low-season pricing, whatever older English pages say. Dollar figures use the ECB reference rates of 18 September 2026.
Is the cave museum included in the ticket?
Yes. Cave admission covers the museum and the app guide in English, German and French. Museum-only entry is CHF 6 ($7.27), or CHF 3 for children 6 to 16. Note that the museum opens later than the cave – 10.30am in summer, noon in winter – and closes earlier.
Do you need a guide, or can you walk through on your own?
You walk through on your own. The kilometre-long route is built, lit and signposted, with panels in German and English, and the app guide comes with the ticket. Guided tours exist only for groups booked in advance: "Kurz & Präzis" from 20 people at CHF 30 per adult, the "Schnitzel & Jagd" treasure hunt from 20 people at CHF 49, and the food-and-drink tour "Kulinarisch & Sinnlich" from 10 people at CHF 65.
How long does the St Beatus Caves visit take?
About 60 minutes for the kilometre underground. Add 5 to 10 minutes walking up from the car park, plus the museum and, if you have children, the Flimboweg trail. The operator budgets three to five hours for a full family day on site.
Are the caves open in winter?
Yes, all year since 10 November 2025. The winter season runs from 21 November 2026 to 20 March 2027: Monday to Friday and Sunday 10am–5pm, Saturday until 6.30pm. The one exception is the maintenance break, which in 2026 falls from 9 to 20 November. English pages still saying "March to November" or "weekends only in winter" are out of date.
How many steps are there, and how cold is it inside?
297 steps and 87 m (285 ft) of ascent. The temperature holds at 8–10 °C (46–50 °F) with about 95 per cent humidity, summer and winter alike. The walkway and steps are damp, so grippy shoes and a warm layer are not optional extras.
Are the St Beatus Caves wheelchair or pushchair accessible?
No. Narrow passages and the 297 steps make the route impassable with either. The museum and restaurant are step-free, but only via the lower car park P1. With a toddler, use a carrier – the surfaced path up from the car park takes a pushchair, the cave does not.
Is it worth taking children, and from what age?
The operator suggests about five or six upwards. Children are not stuck standing in a tour group, which helps. Outside the cave there is the Flimboweg with four hands-on stations, a playground with a dragon slide and a public fire pit, so a visit stretches to most of a day if you want it to.
How do you get to the St Beatus Caves from Interlaken without a car?
STI bus 21 runs between Interlaken and Thun and stops at "Beatushöhlen" by the entrance: 13 minutes from Interlaken West station, about 40 minutes from Thun. Alternatively the BLS boat to "Beatushöhlen-Sundlauenen", then 20 to 25 minutes uphill on foot. The operator actively pushes public transport because parking is short.
Is there a combined ticket with the Lake Thun boat?
Yes. The BLS combined ticket covers the return journey plus cave and museum entry and halves the admission: from CHF 30.40 from Interlaken West, CHF 48.40 from Thun and CHF 50.00 from Spiez, second class. It is valid on the day of purchase only, and the Spiez departures run only from 28 March to 14 November.
Does the Swiss Travel Pass cover the St Beatus Caves?
Not the admission. The operator lists three discounts and the Swiss Travel Pass is not among them: BLS boat combination 50 per cent, SBB RailAway 20 per cent, Berner Oberland Pass 30 per cent. What the Swiss Travel Pass does cover is the journey – bus 21 from Interlaken or Thun and the Lake Thun boats.
Can you bring a dog?
Yes, for CHF 10, which makes this one of very few European show caves that admit dogs at all. Less relaxed: no eating, drinking or smoking inside, and tripods must be left at the ticket desk. Handheld cameras and phones are fine and explicitly welcomed.
What is the waterfall at the entrance?
The Beatus waterfall, fed by the same underground stream that runs through the whole cave system, drops into the gorge immediately beside the entrance. The surfaced path up from the car park crosses it on bridges and walkways. After rain or during the snowmelt it swells into a double fall – and the path gets wet and slippery.
Is there anywhere to eat?
The Stein & Sein restaurant, with a terrace above Lake Thun, plus a kiosk at the cave entrance. Summer hours are Mon–Thu and Sun 9am–6pm, Fri–Sat 9am–10pm; winter Mon–Fri 10am–5pm, Sat 10am–9pm, Sun 9.30am–5pm. Groups can book Brunch am Fels (CHF 49, children CHF 29) or raclette by candlelight inside the grotto.
Are the St Beatus Caves actually worth it?
As a stalactite cave, no – Postojna and Škocjan are in a different league for sheer scale. What St Beatus has is different: an underground stream with waterfalls inside the mountain, no tour group to keep pace with, a dramatic waterfall and gorge before you even reach the door, and a terrace over Lake Thun afterwards. About 196,000 people came in 2025, the highest number in the cooperative's history.
When is the quietest time to go?
A weekday first thing, or Friday and Saturday evening, when the caves stay open until 9pm in summer and coach parties have long gone. Because the route doubles back on itself, crowding is felt more here than in a one-way cave. Winter is quieter still, and the cooperative now programmes it deliberately with fondue evenings and candlelit tours.
