Grande Hot Springs



Grande Hot Springs is naturally available geothermal water in the Grande Ronde Valley, a half mile west of the historic Hot Lake Hotel. Previously known as Eagles Hot Lake RV Park, Grande Hot Springs is situated on the Hot Lake.

Until 1994, RV Resort on the east part of the Hot Lake was a part of the Hot Lake Springs property. After splitting into several parcels, the RV Resort and Hot Lake Springs have different owners.

The Hot Lake receives from ground springs 2 million gallons 186°F (86°C) thermal water a day. Pumped from the Hot Lake, a little cooler the 171°F hot water is used in the pools and private soaking tubs in yurts as well as for heating all buildings. The hot water is mixed with a well water to make a soaking temperature comfortable. The 77°F well water is also mineral and meets state drinking water standards.

There are the 30-foot in diameter soaking pool and 6-by12-foot pool (spa) behind the main lodge. The water is maintained about 95-degree and 103-degree Fahrenheit accordingly. If you prefer secluded soaking, yurts with soaking tubs on the private patio are available for reservation.

On the 24-acre property, there are the 100 RV sites with full hook-up service, tent sites, group tent area, and yurts. The public pools are open seasonally (April-October) from 9 a.m. to 8 p.m, though they can be open in winter (call to find out). Soaking is available year-round in the private soaking tubs in the yurts.

The main lodge has a small grocery store, a laundry, and showers.

There is a mile-long natural trail through the Ladd Marsh Wildlife sanctuary, a great place to hike while observing a variety of waterfowl species.
