Come to Interlaken from June to September and there’s a dizzying amount of things to do outside.
Top of your list should be to rent a kayak or stand-up paddleboard for Lake Thun or Brienz, and there are lots of companies to consult for this.
On land you might be ready for something more exciting than a simple hike.
The terrain around the lakes couldn’t be better suited to canyoning: You’ll don safety gear and a neoprene suit and rappel down waterfalls and gorges.
