Viral cave-pool Reel is Ainsworth Hot Springs: the Kootenay history, location and map
A Facebook Reel shared to NewsForBC describes a cave pool as “Mother Nature’s Sauna.” The video transcript identifies the place as Ainsworth Hot Springs, a resort and hot-springs community on the west shore of Kootenay Lake in southeastern British Columbia.
The clip is short and dramatic: warm water, glowing cave walls, a tunnel-like pool, and narration about a 150-foot cave system. But the actual B.C. story is better than a viral caption. Ainsworth sits in Ktunaxa traditional territory, developed through a mining-town period, and is now owned by the Lower Kootenay Band/Yaqan Nukiy.
Where it is
Ainsworth Hot Springs Resort is listed by the resort at 3609 Balfour-Kaslo-Galena Bay Highway, Ainsworth Hot Springs, B.C. OpenStreetMap/Nominatim returns the resort at approximately 49.7353933, -116.9112400, beside Kootenay Lake north of Nelson and south of Kaslo.

The cave and water system
The resort’s pool page says the hot springs originate around the Cody Caves above and east of the resort. Water flows through fractures in rock, warms as it descends, hits a lakeshore fault, and is forced upward by hydraulic pressure until it emerges at the resort.
According to the resort, the mineral water enters the system at 47°C / 117°F, then is cooled to about 42°C / 108°F for the 150-foot horseshoe caves and about 35°C / 96°F for the main lounging pool. The same page notes that, under Interior Health pool-operation requirements, chlorine is added and the cave and pools are tested several times a day.
Ktunaxa history and “spirit water”
The official history page opens with a welcome from the Lower Kootenay Band and places the hot springs in the traditional homelands of the Ktunaxa people. It describes the waters as nupika wu’u, or spirit water, used since time immemorial as a place of healing and rejuvenation.
The history page says Ktunaxa people used the waters after hunting, fishing, gathering, battle and for ailments such as arthritis. That makes the site more than a spa stop: it is a long-used cultural and healing place now being presented through a Ktunaxa-owned hospitality lens.
Mining town to resort
The place later became tied to the Kootenay mining story. The resort history says that in 1882, George Ainsworth of Portland, Oregon, applied for a pre-emption of the townsite, then known as Hot Springs Camp, on the strength of nearby silver, lead and zinc discoveries.
Commercial development of the hot springs came later. The history page says Nelson’s John Burns put in a pool and began developing the springs commercially in the 1920s, as the mining centre was declining. By the early 1930s, the pool and caves were finished, even as the Great Depression was underway.
Through the 1930s, 40s and 50s, various lessees operated the pool. The official history says a swim cost 10 cents in the 1930s, mining production peaked in the 1940s and early 1950s, and silver-price declines later helped close the mines.
Return of Ktunaxa ownership
The resort history says Ainsworth Hot Springs Resort and surrounding properties were purchased in 2015 by the Lower Kootenay Band in Creston. It describes that return of Ktunaxa peoples to an important site in their traditional homeland as “incredibly significant.”
That ownership detail is the piece many viral travel clips miss. The hot-springs cave is visually striking, but its full story runs through Ktunaxa land, healing traditions, mining history, Kootenay Lake tourism and modern Indigenous ownership.
Travel context
The resort’s contact page lists approximate driving times of 20 minutes from Kaslo, 45 minutes from Nelson, 3 hours from Cranbrook, 4 hours from Spokane, 5 hours from Kelowna, 7 hours from Calgary, and 8.5 hours from Vancouver. Visitors should check current pool hours, access rules and road conditions directly with the resort and DriveBC before travelling.
What the Reel gets right
The Reel’s “Mother Nature’s Sauna” framing is fair as a visual hook, and the transcript’s key location claim checks out: it is Ainsworth Hot Springs in the Kootenay region. The more complete B.C. version is not just a pretty cave. It is a Kootenay Lake place where geology, Ktunaxa history, mining settlement and tourism all meet in one warm-water corridor.
