About Soap Lake Natural Spa and Resort
Soap Lake Natural Spa and Resort, Washington is a paid lakeside resort at 236 Main Ave E in the town of Soap Lake, Grant County, in central Washington. The resort is not a geothermal hot spring. It is built on the shore of Soap Lake, a naturally alkaline mineral lake containing 23 dissolved minerals formed during the Ice Age when groundwater filtered through basalt layers and absorbed minerals from the surrounding rock. The lake is one of only two meromictic soda lakes of its type in the world, meaning its distinct water layers never mix. One of its most remarkable characteristics is its extraordinary mineral diversity, which has drawn visitors seeking therapeutic benefits for well over a century.
The resort offers in-room mineral water tubs in select rooms and cabins, fed directly with Soap Lake water alongside a standard fresh water option. Six outdoor hot tubs, an infrared spa, dry sauna, gym, private beach access, and a restaurant are on site. Accommodation ranges from historic inn rooms in a 100-year-old cobblestone building to log cabins and cottages. The resort also offers yoga classes and a gift shop. It is now affiliated with the Dazzler Select by Wyndham brand and operates year-round.
