Why Interlaken in Switzerland is this autumn’s travel hotspot

Lake Thun is a sight to behold at the best of times, given the small matters of its extreme natural beauty and the breathtaking, panoramic views over the water.  

Look up, however, and there’s an adventure to be had. High above the lakes lie the limestone St. Beatus Caves – easily accessible by bus, boat or car. Within this natural wonder, millions of years old, visitors can explore a kilometre of illuminated pathways leading through rock formations, vast chambers, waterfalls and underground streams shaped by nature over millennia. 

And if you happen to be hungry after your underground discoveries, the nearby Restaurant Stein & Sein will have you well-fed in more ways than one: enjoy Swiss delicacies, while taking in the sights on its spectacular terrace, which overlooks the lake and the Bernese Alps.

Autumn is one of the most magical times to explore Lakes Thun and Brienz, as the surrounding forests turn to rich shades of red and gold, carpeted by leaves. The historic castles, picturesque villages and turquoise waters of the region all create the makings of a stunning autumn escape. 

Cruises on the lakes vary depending on what you’re looking for: the Breakfast Special and Afternoon tea cruises offer the chance to indulge and unwind in front of some jaw-dropping views, while the Board Games cruise, available on both lakes, invites guests to play new games and classics alongside experts from Delirium Ludens. For families, the Globi Adventure Cruises on Lake Thun feature entertainment including music, magic, and dance games. There’s truly a boat ride for everyone!

Autumn is the ideal time to discover the collection of castles around Lake Thun: step back in time at the medieval Thun Castle, with its four striking towers, then stroll through Schadau Park to the elegant Schadau Castle. 

Along the lakeshore, you’ll find Hünegg Castle, which boasts a historic Art Nouveau interior, while romantic Oberhofen Castle looks like it’s straight out of your favourite Disney movie. Across the lake, Spiez Castle stands just above the picturesque bay, surrounded by vineyards and mountain views. Nothing special, then…
