In the Newberry National Volcanic Monument, this paved interpretive loop trail helps you discover the strange world of tree molds formed 7,000 years ago by molten lava. Some sections are too narrow or steep for wheelchairs.
From Bend, head south on Highway 97 for approximately 15 miles. Get off at the Sunriver exit and turn left (heading east). Follow the gravel Forest Service Road #9720 approximately 10 miles until it dead ends at the trailhead.
