Barbecue spots by Lake Tannen 
Spacious barbecue spots are available at the lake's dam and on the eastern shore; they're equipped with dry firewood and grilling implements.

Lake Tannen is used by the Elektrizitätswerk Obwalden power generator, which is why its water level goes up and down depending on electricity requirements.
