A hike around beautiful Lianvatnet takes around 40 minutes and is easily accessed from Trondheim. The Lian station, the terminus of the Gråkallbanen Line, is a great place to start your hike. Neighbouring Haukvatnet is another good option for a scenic lake hike.

Lianvatnet is on the very eastern fringes of Bymarka, not too far from the city. Its grassy surroundings are great for a picnic, while the lake is a popular fishing spot, though you'll need a license. A loop of the lake takes around 40 minutes.
