Mule Canyon is located on an unmarked county road SJC263 on the north side of UT95 at mile market 102.3. Park about .3 mile after leaving UT95 for House on Fire in the south fork of Mule Canyon.
A small fee is required to visit the canyon and is well worth it. Visit in the early am in summer as the sun will be too bright in the afternoon and burn out the details on the ceiling of the ruin.
House on Fire Ruin is located in Mule Canyon and is a very easy hike with litle change in elevation.
