01
Closest sandy swim spot
Diaz Lake Recreation Area Beach
Near Lone Pine Along Us-395 • Low-Key Desert Lake Beach • Closest True Swim Beach To Olancha
A laid-back shoreline just north of Olancha with easy access, mellow water, and big Sierra views.
Diaz Lake is the spot locals point to when you ask where to swim between Olancha and Lone Pine. The beach area is simple but pleasant, with room to spread a towel, launch a kayak, or let kids splash close to shore. Expect classic Owens Valley scenery—granite peaks to the west, open desert to the east, and brilliant stars if you stay through dusk.
02
Best for full-day outings
Lake Isabella – South Fork Beach
Over Walker Pass West Of Olancha • Big Reservoir Beach With Room To Roam • Best For Boat Days And Group Trips
A broad, often breezy stretch of shoreline that feels like a classic California reservoir beach day.
Crossing Walker Pass drops you into Lake Isabella country, where the South Fork side offers long arcs of sand and easy lake access. It is a solid choice when you want a full day on the water, with space for coolers, shade tents, and a mix of paddling, swimming, or just sitting in a camp chair by the shore. Afternoons can get windy, so many locals aim for earlier in the day during summer.
03
Most scenic escape
June Lake Beach
June Lake Loop Off Us-395 • Alpine Lake Beach With Turquoise Water • Best For Mountain Scenery And Swimming
A genuine sandy beach on a clear mountain lake, ringed by dramatic granite peaks and pine forest.
June Lake Beach feels a world away from the high desert around Olancha, even though it is just a drive up US-395. The sand here is real, the water is startlingly blue on sunny days, and the backdrop of cliffs makes even a casual swim feel special. Bring layers—the lake stays cool and the air can shift quickly at this elevation.
04
Windy wide-open shoreline
Crowley Lake North Shore
Long Valley South Of Mammoth Lakes • Open Reservoir Shoreline With Big Skies • Best For Fishing And Breezy Afternoons
A broad, exposed lakeshore where anglers, paddlers, and lake-day regulars spread out along the water.
On Crowley Lake’s north side you will find pullouts and informal beachy stretches that feel more like a working lake than a groomed swim area. It is a favorite among anglers and paddlers who do not mind some wind in exchange for space and views. Pack shade, sturdy footwear for mixed sand and gravel, and a windbreaker if you plan to linger into the afternoon.
05
Best pine-fringed swim spot
Horseshoe Lake Beach, Mammoth Lakes
Mammoth Lakes Basin • Pine-Ringed Mountain Lake Beach • Best For Picnic-And-Paddle Days
A compact sandy beach at the edge of a forested lake, popular with swimmers, dogs, and paddlers on warm days.
Horseshoe Lake’s small beach area punches above its size, thanks to the mix of sand, shallow entry, and shady pines just steps away. Families and casual swimmers like the gentle shoreline, while paddlers enjoy a quick carry from the car to the water. It pairs easily with a half-day in Mammoth—coffee in town, then a relaxed swim and picnic up in the basin.
