Visiting St. Beatus Caves in Switzerland: What to Know Before You Go

On one of the hottest days of our Switzerland trip, we headed to St. Beatus Caves above Lake Thun. Stepping into a cool cave after being outside in the heat was pretty refreshing.

The caves were a memorable experience during our time in Switzerland, with underground streams, reflecting pools, unusual rock formations, and a little bit of legend involving a dragon.

But there’s something you should know before you go: St. Beatus Caves are not an easy stop for everyone. The walk up to the caves is quite steep, and several people in our group decided it wasn’t worth the climb.

For context, we were traveling as a multigenerational group of seven adults with a range of mobility levels, so accessibility was something we paid particular attention to throughout the trip.

For those of us who made it up, though, the caves were definitely worth seeing.

For us, the biggest consideration wasn’t actually the caves — it was the steep walk up to them.

Getting to St. Beatus Caves

Save

We took the bus to St. Beatus Caves from Interlaken, winding along the gorgeous Lake Thun. The walkway entrance is across the street from the bus stop.

From there, a paved switchback path winds through the woods and includes several bridges, with the waterfall from the caves rushing down alongside the path.

Save

It was also where we discovered that the approach was going to be a bigger challenge than some of our group had anticipated.

The walkway is steep.

Several members of our group took one look at the entrance and decided to stay at the tables near the bottom rather than make the climb. They grabbed some ice cream, sat in the shade, and even cooled off with the water from a nearby fountain while they waited for us.

Save

There’s a restaurant near the top, but the steep walkway made it unrealistic for the people who stayed below to get up there. The official site also notes that the area, including the caves, is not wheelchair accessible.

If you’re traveling with older adults or anyone with mobility limitations, this is something I’d take seriously when deciding whether to visit.

We also explored the area around Interlaken with a guided tour of Lauterbrunnen Valley, another day trip that gave us a very different perspective on this beautiful part of Switzerland.

Exploring the St. Beatus Caves

Once inside, the experience was completely different from what was happening outside.

The caves stay cool even on a hot summer day, and we definitely appreciated that.

The four of us who opted to explore made our way through the caves, following the path through the underground chambers. The caves are part of a much larger system, with around 8.7 miles of passages explored, although visitors can walk through roughly 0.6 miles of the cave system.

Save

The path was decently well lit, but it wasn’t a perfectly smooth walk. There were uneven sections and some stairs, and there was quite a bit of water around us.

It was wet inside, but we didn’t find the walking surfaces particularly slippery.

An Underground Landscape

What I liked most was how much there was to look at.

Water was still running through the caves, and we passed reflecting pools and intricate rock formations that looked almost otherworldly.

It felt completely different from the Swiss landscapes we’d been enjoying above ground. Instead of mountain peaks and lake views, we were surrounded by dark rock, water, and strange formations created over thousands of years.

Save

The caves are also surprisingly well lit. The lighting made it possible to appreciate the shapes and details without feeling like we were simply walking through a dark tunnel. Signs are posted frequently throughout the cave, so you can learn more about what you’re looking at along the way.

The Legend of St. Beatus and the Dragon

Of course, there’s a little more to St. Beatus Caves than geology.

According to the legend, St. Beatus came to the area and eventually drove a dragon out of the caves. The story is part of what gives the caves their name and adds a fun bit of mythology to the visit.

I’m always a fan of places where there’s a story attached to what you’re seeing. It makes the experience feel a little more memorable than simply walking through a natural attraction.

Visiting During a Drought

Save

One thing that affected our visit was the drought in Switzerland that summer.

There was much less water flowing through the caves than usual, so I imagine the experience can look quite different depending on conditions. Some of the pictures I’d seen online before our trip showed significantly more water and much more dramatic falls.

Even with the lower water levels, we still had plenty of water running through the cave system and enjoyed the reflecting pools and underground streams.

It was also a welcome break from the heat outside.

Is St. Beatus Caves Worth Visiting?

For us, yes.

We went in expecting a cave walk and ended up exploring an underground world of water, rock formations, and reflecting pools that felt completely different from everything we’d seen that day.

And on a hot summer day, the cool temperature inside the caves was a bonus.

But I wouldn’t recommend St. Beatus Caves without a caveat.

The steep approach makes this a challenging stop for some travelers. Several people in our group weren’t able to comfortably make the climb, and I think that’s important to know before you put it on your itinerary.

Save

If your group is comfortable with a steep uphill walk and uneven terrain, though, I think St. Beatus Caves are a fun addition to a Switzerland itinerary.

It was also a good example of something we learned during this trip: your entire group doesn’t have to do every activity together.

For example, when we visited Stoos Ridge, my husband and I tackled the ridge hike while the rest of our group enjoyed the spectacular mountain views from a ridgetop restaurant. St. Beatus was the opposite—the rest of the group skipped the steep climb while four of us explored the caves.

For a multigenerational trip or a trip with different activity levels, sometimes splitting up for an hour or two means everyone gets to enjoy the day.
