The eastern side of the mountain hosts a ski resort, Vassfjellet Skisenter. The {{convert|710|m|adj=on}} tall mountain lies about {{convert|4|km}} southeast of the village of Melhus.
At the top there is a radio and television transmitting tower, which extends {{convert|220|m}} above the top of the tall mountain. A road leading to the top has been built for maintenance access to the tower. This road starts in the village of Kvål in Melhus Municipality, but is closed to public vehicle access. It is however an excellent route for hiking.
The Vassfjell Chapel is located on the northeast side of the mountain in Trondheim Municipality.
