This trail makes for an easy walk along the rim of Pinnacle Valley. There are great views of volcanic spires. Use caution near cliffs. Trail ends at park boundary. Accessible to wheelchairs with assistance. open to bicycles.
These needle-like formations of rock, called fossil fumaroles, projecting from the Sand Creek Canyon floor, were formed under sheets of volcanic pumice that preceded Mazama’s collapse. As the surface of the hot pumice cooled over the years, steam and gases were released by the hot rocks underneath through vents and tubes that were welded into cement hardness by their passage. These ancient vents now stand alone due to the erosion of the surrounding softer materials.
Trailhead Location: The trailhead lies at the end of the Pinnacles Spur Road, 7 miles (11.3 km) Southeast of the Phantom Ship Overlook off of the main Rim Drive, on the southeast corner of the park.
Nature Note: The Pinnacles are chimneys formed when hot ash cooled after the big eruption.
Seasonal Information: Expect the trail to be covered in snow from October to early July, however, conditions vary somewhat from year to year. See Crater Lake Current Conditions for more information.
