Lake Tannen is very popular with anglers. Six different species of trout and char are released in this beautiful mountain lake. In winter, ice fishing is offered on the frozen lake.
There are spacious barbecue areas by the Tannen dam and on the eastern shore. Dry wood and grills are available - making grilling sausages child's play for the whole family.
Signposted footpaths lead around the lake. They are stroller-friendly.
Frutt-Zug road train
The Frutt-Zug runs between Melchsee-Frutt and Tannalp. There are two stops by the lake at the dam and the barbecue spot.
An unmetalled road runs along the southern shore which joins the access road at both ends. The neighbouring mountains are the Hohmad (2441 m) in the north, the Reissend Nollen (3003 m) in the east, the Wendenstöcke (up to 3042 m) and the Glogghuis (2534 m) in the southwest.
Lake Tannen, like Lake Melch, is used by the Elektrizitätswerk Obwalden (EWO) to produce electricity, so its water level is subject to fluctuations depending on the demand for power.
