Ainsworth Hot Springs Resort

Tucked into the Purcell Mountains of British Columbia, Ainsworth Hot Springs offers a geothermal experience unlike any other. The resort’s crown jewel is its 150-foot horseshoe-shaped cave, where mineral-rich waters cascade from the ceiling and walls, enveloping visitors in a steamy, subterranean sanctuary. With temperatures reaching 42°C, the cave provides an invigorating natural steam bath, complemented by a nearby cold plunge pool for a refreshing contrast.The main outdoor pool, maintained at a comfortable 35°C, overlooks Kootenay Lake.

Ainsworth Hot Springs Resort is owned by the Yaqan Nukiy, the Lower Kootenay Band of the Ktunaxa Nation, who have used these mineral waters, known as nupika wu'u, or spirit water, for healing since long before the resort existed. Beyond the pools, guests can indulge in treatments at the Spirit Water Spa or dine on locally-inspired dishes at the Ktunaxa Grill, with lake views from its rooftop patio. Guest rooms sit mountainside above Kootenay Lake, with the newer Yaqan Nukiy Suites adding balconies over the lake and the Purcell Mountains. A restored 1896 building, the JB Fletcher Store, now houses a small museum and an artisan shop selling local work.
