On Lake Thun’s south shore, Spiez is a picturesque town wrapped in vineyards and reached by car, train or boat in a matter of minutes from Interlaken West.
The town is crested by the powerful square keep of its castle, which was first built in the 13th century and gained its current appearance in the 1600s.
This is well worth a visit, along with the 1,000-year-old Romanesque church, and has information in three languages about the succession of noble families that owned the castle under the Kingdom of Burgundy and Habsburg Empire.
