Paulina Lake Hot Springs consist of numerous thermal springs emerging from the bottom of the Paulina Lake. Most of the hot springs are secured by the lake and mixed with its cold water. Fortunately, there are a few hot springs on the north shoreline that are accessible by foot or by boat.
Paulina Lake is one of two alpine lakes nestled in the Newberry Caldera. A large volcanic crater is one of the most active geothermal areas in the United States. As a result of past volcano activities, the caldera was created hundreds of thousands years ago, when overlying volcano's rocks collapsed. The second lake of the Newberry Caldera, East Lake is located 2 miles east of the Paulina. East Lake also has hot springs on its shore, known as East Lake Hot Springs.
On the shore of the Paulina Lake, you can find five or more man-made pools along the quarter-mile length gravel Hot Springs Beach. Some of the pools are reinforced by logs. The hot springs bubble up from the depth through the black and red volcanic gravels.
In early springs, when the water has the highest level, the hot springs on the beach are submerged with the lake and become exposed only when the water level drops. The best time to visit Paulina Lake Hot Springs is May through July when the soaking pools have enough water to cover a bather. When the water level in the lake is too low, the hot spring pools don't have enough water even for feet soaking.
The actual temperature of the water depends on the time of year and varies between 90 and 115 degrees Fahrenheit. The temperature of the source located directly out of the ground has been reported as high as 176°F. The geothermal water has no smell of sulfur.
According to USDA Forest Service, because this is a riparian zone, you should use existing soaking pools, new pools digging is not allowed.
Camping and fires are prohibited on the Hot Spring Beach.
