Dogs must be leashed between April 15 and August 15.
The trail starts and ends next to the football field down behind the high school. Probably due to highschoolers, the area just in the beginning has a large amount of wear on the trail, and seems very techy. Don't worry, it's not like that the whole way around!
The trail is clearly marked with blue paint on the trees, and signs at the fork. Follow the signs to "Heer/Måna" to avoid getting lost in the trail system.
As you ride around the lake, the trail winds into lots of small rock outcroppings and good picnic or swimming areas. Some even have buoys for life saving and some pre-made bonfire spots.
Although the trail can be done both ways, I highly recommend you start off going south (rider's right) around the lake. This will have you hitting a lot of the techy parts going downhill, instead of having to try climbing it (and probably end up walking).
