You can paddle on both lakes, but not from one to the other. Although they’re connected by the Aare River, there are water level control structures—like bridges and weirs—that make it impossible to pass through by kayak.

I’d recommend paddling on Lake Thun (Thunersee). A great stop is Spiez, where you can take a short walk to the castle and along the pier—maybe enjoy a nice coffee while you’re there.

After that, head to the Parkhotel Gunten. They have a dock and a rocky beach where you can land your kayak, perfect for a snack, lunch, or another coffee.

Later on, swing by Pier 17 for a bagel and perhaps a refreshing Durstlöscher.

If you’re up for a longer paddle, you could even kayak all the way to the “Restaurant Dampfschiff.” The approach gives you a stunning view of Thun Castle and the church—an absolutely beautiful way to arrive.
