Lake Brienz to the east of Interlaken has a turquoise tone and mountain views.
Steamboats have been chugging across this lake since the 1830s and there’s now a small armada of five vessels from the first decades of the 20th century.
These set off for destinations around the lake, like Giessbach, site of the castle-like Grand Hotel Giessbach and a waterfall that plunges 500 metres to the lake.
