A scenery ride and not challenging enough to be a destination ride, there are a number of jeep trails which could be used to make this into a much longer loop but it is good enough as an end-of-day or last-day OAB ride.

The 1mi Lava Butte road ascends 470' (9% incline). The other 5.3mi. 420' ascent is at a 1.5% incline.

The ride can be extended by starting from one of the Deschutes Rvr Tr2 campgrounds and riding to Lava Butte.
