Spiez Castle is a medieval-style attraction in the village of Spiez by Lake Thun, near Interlaken. The castle holds a museum inside and visitors can climb to the top for views of the lake and the mountains. A cruise boat crossing Lake Thun from Interlaken West reaches it in under five minutes, and inside, bags go in lockers and photos are taken without flash. In the off-season, the cafe and the interior are closed.
