Perlite Road to Arnett Creek Loop

Route Description for Perlite Road to Arnett Creek Loop

The Perlite Road to Arnett Creek Loop leads you through the grounds of the Boyce Thompson Arboretum and then through a canyon at the base of Picketpost Mountain. If you’re planning a trip to the arboretum but want to spend some time outside and exploring, consider this hike as an addition to your adventures.

This loop is not well defined in all parts and can be hard to follow. We strongly recommend downloading a GPS route to follow. We also recommend hiking this loop counterclockwise so should you lose the trail, you can backtrack through the grounds of the arboretum, which is easier to do than finding your way along the other side of the loop.

From the trailhead, hike up towards the highway and turn left towards the arboretum. Hike alongside the creek and through the grounds past the lookouts. You’ll round the hill between the creeks and turn east to hike through the canyon that Arnett Creek flows through. Look for the trail and heads left out of the canyon and use this to find Perlite Road again.
