One of the most conspicuous sites of Sarni is a Shiva temple overlooking the town from Mathardev peak, which is the highest point, approximately 3,500 ft (1,100 m) (from sea level), among neighbouring hills of Satpura ranges. The peak as well as the temple are named after a legendary tribal chief named Mathardev. The legendary chief commands strong following among the local and neighboring population.
The path to the peak is a steep trek climbing two hills. It takes approximately 35–40 minutes of continuous climb at walking pace to reach the top.
