Crowley Lake Columns: Sightseeing Guide

August 19, 2026

The eastern shoreline of Crowley Lake hides one of the most unusual and visually striking geological wonders in the region.

The Crowley Columns stand as a delicate intersection of science, art, and time. These fragile pillars reveal the incredible artistry of volcanic erosion. A Crowley Lake Columns visit offers a rare glimpse into the powerful forces that shaped this landscape.

What You Will See

At a glance: Column height: 15-20 ft | Access: By boat only | Launch point: Crowley Lake Fish Camp (~1.5 miles east) | Rentals available: May through October | Estimated visit time: 1.5-2 hours

As you approach from the water, temple-like archways and towering pillars emerge from the cliffs. Many of the columns reach heights of 15 to 20 feet. They are often spaced about a foot apart and ringed by horizontal cracks every 12 inches.

Some formations are straight and gray, while others tilt and curve to create intricate shapes. A few remain partly submerged or half-buried, giving them a fossilized appearance.

These features were formed by steam and mineral cementation within hot volcanic ash after the Long Valley Caldera eruption roughly 760,000 years ago. They are very different from the classic basalt columns you will find at Devils Postpile. Researchers estimate up to 5,000 of these structures may exist over a few square miles.

Best Time to Visit

Late spring through early fall offers the safest boating conditions and the best weather for exploring. The appearance of the columns changes dramatically depending on the season and the reservoir levels.

During high-water years, the pillars are partly submerged and best seen intimately from a kayak. Late summer and fall bring lower water levels that expose more of the formations. Access remains limited to watercraft year-round due to the safety concerns, trespass risk, and a high potential for damage to these fragile geological wonders.

Photography Tips

If you are planning for Crowley Lake photography, Mammoth Lakes provides an incredible basecamp for your creative outings. The columns are best experienced and photographed directly from the water.

Plan for a one-and-a-half to two-hour visit to allow plenty of time to travel across the water and frame your shots. Morning or late afternoon light provides the best contrast and casts striking shadows across the gray stone.

Always maintain a safe buffer distance from the cliffs to avoid causing wave erosion. You should never touch, climb on, or remove any rock material from these sensitive geological formations.

How to Get There from Mammoth Lakes

The columns are located about 25 minutes south of Mammoth Lakes along the eastern shoreline. The safest and most responsible way to view them is by launching a non-motorized craft or boat from Crowley Lake Fish Camp.

The marina provides flat, paved access to rental boats and restrooms, and staff can assist visitors with limited mobility. From the marina, you will paddle or motor east across the lake for about one and a half miles to reach the base of the cliffs. Rentals are typically available from May through October.

Land access is strongly discouraged. Rough four-wheel-drive routes like Owens Gorge Road often contain areas of deep sand that trap vehicles. The steep, unmaintained trails are prone to landslides and cross restricted property managed by the Los Angeles Department of Water & Power. There are no restrooms, trash bins, or picnic tables near the columns themselves.

Combine with Nearby Stops

When looking for Crowley Lake things to do, you can easily turn your visit into a full-day itinerary. While on the water, enjoy fishing, birdwatching for ospreys, pelicans, and migratory waterfowl.

Many visitors pair their outing with a picnic at the marina or the nearby community park. You can also combine this trip with a visit to the bubbling geothermal pools at Hot Creek or an afternoon hike around the stunning granite basin of Convict Lake.

Plan Your Overnight Stay

After a peaceful day exploring the water and admiring ancient volcanic art, you will want a comfortable place to relax. Browse lodging options in Mammoth Lakes and make a full Eastern Sierra adventure of it.

Frequently Asked Questions

Here are answers to the questions visitors ask most about the Crowley Lake Columns.

What are the Crowley Lake Columns?

Volcanic columns formed by steam and mineral cementation within hot volcanic ash after the Long Valley Caldera eruption roughly 760,000 years ago. Up to 5,000 structures may exist along the eastern shoreline, reaching heights of 15 to 20 feet.

How do you get to the Crowley Lake Columns?

The only responsible access is by watercraft. Launch from Crowley Lake Fish Camp and paddle or motor about 1.5 miles east to reach the base of the cliffs. Land access is strongly discouraged due to the fragility of the columns and their environment, unstable terrain, and restricted property.

Can you visit the Crowley Lake Columns year-round?

Boat rentals are typically available from May through October. The appearance of the columns changes with reservoir levels—high water partly submerges them, while late summer and fall expose more of the formations.

How long does a visit take?

Plan for one and a half to two hours on the water to travel across the lake and photograph the formations comfortably.
