Crowley Lake sits just south of Mammoth Lakes and is best known for its dramatic Crowley Lake Columns—towering volcanic rock formations that line the lake’s shoreline like something out of another world. These mysterious columns were formed thousands of years ago by cooling ash from the Long Valley Caldera eruption, later revealed by wind and water erosion. Reaching them takes some effort: you’ll need to drive a rough dirt road (best for high-clearance 4WD vehicles) and then hike about 1.5 miles round trip along the lakeshore to the base of the columns. The trail itself is mostly exposed, so it’s best done early or later in the day to avoid the heat. While the lake is popular for fishing, paddleboarding, and boating, the columns offer a more off-the-beaten-path adventure—one that feels like uncovering a secret piece of the Eastern Sierra’s geologic history.

See our map for the best place to park and hike from if you do not have a high clearance 4x4 vehicle.

Pet-friendly: Yes, but must be leashed, well-behaved and picked up after. Also, unless you go very early, or very late, we wouldn't recommend bringing your pup due to the heat and exposure. If you do bring them, bring plenty of water and maybe even booties.

Soft adventure: Definitely not, whether you drive or hike.
