South Harney Lake Hot Springs is Closed to Public

South Harney Lake Hot Springs is located inside of the Harney Basin - a caldera depression that has been created 32,000 years ago when huge lava flows separated the basin from the Malheur River.

Found at the southeastern edge of Harney Lake, South Harney Lake Hot Springs is a collection of bubbling hot springs with a distinct sulfur smell. The temperature of the geothermal sources is over 150 degrees F. The mineral water cools down while flowing from the colorful hot pond through the flat sagebrush landscape into the narrow channel. According to GTILO, South Harney Lake Hot Springs is the second hottest geothermal resource in the Harney Basin. The flow of the springs is greater than 450 liters per minute.

The plastic tub or any container is one of the options to take a soak. You can fill it with hot water from the channel. The water downstream of the pools is cleaner and hot enough at about 100-110°F to take a bath. Overall, this hot springs doesn't provide the cleanest or safest soaking experience, due to its very high temperatures, muddy interior, and possible red spider mites.

It is not recommended to travel to the hot springs until mid-summer. The last 8.5 miles of unimproved road is likely to be either snowy or incredibly muddy during the winter and spring seasons.

Though the hot springs are located on private land, it's available for public use. No signs are indicating if overnight camping is prohibited here but we suggest looking for BLM camping options.
