From natural hot springs and alpine lakes to reservoirs and refreshing mountain creeks, Inyo County offers plenty of ways to cool off during the summer. Whether you’re taking a quick dip after a hike, relaxing in naturally heated mineral waters, or spending the afternoon at a lakeside beach, you’ll find unforgettable swimming opportunities surrounded by some of California’s most spectacular scenery.
Because many of Inyo County’s waters are fed by snowmelt, even the warmest summer days often come with surprisingly cold water. Always use caution around rivers, creeks, and mountain lakes.
Best Places to Swim in Inyo County
Keough’s Hot Springs
Located just south of Bishop, Keough’s Hot Springs is one of California’s oldest natural hot spring resorts. The facility features a large naturally heated swimming pool, a soaking pool, picnic areas, and changing facilities, making it one of the county’s most popular places to swim and relax year-round.
Owens River
Several accessible sections of the Owens River provide opportunities to wade or cool off or float during the summer. Because river currents and water releases can change quickly, visitors should avoid swimming in fast-moving water.
Big Pine Creek
Flowing from the glaciers of the Sierra Nevada, Big Pine Creek offers numerous scenic places to cool your feet or enjoy a refreshing dip. The water remains extremely cold, even during midsummer.
Bishop Creek
Bishop Creek Canyon is home to several beautiful creekside areas where visitors can relax, wade, or cool off after hiking or fishing. Exercise caution around swift currents, slippery rocks, and changing water levels.
Alpine Lakes
For adventurous hikers, Inyo County’s alpine lakes provide unforgettable places for a refreshing swim after reaching the trail’s end.
Popular destinations include:
- Big Pine Lakes
- Long Lake
- South Lake
- North Lake
- Lake Sabrina
- Treasure Lakes
- Cottonwood Lakes
These lakes remain cold throughout the summer due to their high elevation and snowmelt, and can be dangerous. Dip cautiously.
Swimming Safety
Before entering any natural body of water:
- Expect cold water temperatures, even in summer.
- Never dive into unknown water.
- Watch for slippery rocks and uneven footing.
- Avoid swimming in fast-moving rivers or near dams and spillways.
- Supervise children at all times.
- Wear a life jacket when recreating from boats, kayaks, or paddleboards.
- Afternoon thunderstorms can develop quickly in the mountains.
Cold-water shock can occur even on warm days, especially in alpine lakes and snowmelt-fed rivers.
Best Time to Swim
Swimming is generally most enjoyable from late June through early September, although water temperatures vary depending on elevation and snowpack.
Lower-elevation destinations such as Keough’s Hot Springs and Diaz Lake are enjoyable for much of the year, while alpine lakes are typically accessible from midsummer into early fall.
Recreate Responsibly
Help protect Inyo County’s lakes, rivers, and streams by practicing responsible recreation.
Pack out everything you bring with you, avoid using soap or shampoo in natural waterways, stay on established trails when accessing the water, and respect wildlife and sensitive habitats. Many of these waters provide critical habitat and drinking water for downstream communities.
By recreating responsibly, you help preserve Inyo County’s waterways for future generations to enjoy.
