Popcorn Cave Trail Professional Guide
Detailed Trail Description from our Guidebook
"This graded cinder loop starts and finishes just off California 299 and travels through an arid volcanic region that is part of the Modoc Plateau. The trail passes stands of ponderosa pines, oaks, and manzanitas. It is a short, pleasant drive suitable for passenger vehicles in dry weather. Midway around the loop, a short spur leads to a parking area alongside a volcanic boulder field. The large rocks are the site of Popcorn Cave and Big Cave. Although very hard to spot, it is fun to scramble over the rough boulders and explore the depressions and ridges of hardened lava. Special Attractions: Easy trail through a volcanic region; Volcanic landscape around Popcorn Cave and Big Cave. High-clearance 4WDs are preferred, but any high-clearance vehicle is acceptable. Expect a rough road surface; mud and sand are possible but will be easily passable. You may encounter rocks up to 6 inches in diameter, a loose road surface, and shelf roads, though these will be wide enough for passing or will have adequate pull-offs."
