Radium Hot Springs

## Overview Radium Hot Springs is one of Canada's largest and most popular natural hot springs, nestled at the southern entrance of Kootenay National Park in British Columbia. Surrounded by the dramatic limestone walls of Sinclair Canyon, this geothermally heated mineral spring has drawn visitors from around the globe for well over a century. The springs take their name from the trace amounts of radon (a radioactive element once commonly called "radium emanation") detected in the water during early 20th-century analyses — though the levels are negligible and the water is not considered hazardous. The hot spring water originates deep underground, rising through ancient faults in the Precambrian and Paleozoic rock of the Rockies before emerging at the surface. The water is odorless and notably low in sulfur compared to many other hot springs in the Canadian Rockies, which makes for a more pleasant soaking experience. Historically, the springs were known and used by Indigenous peoples long before European contact. In the early 1900s, businessman Roland Stuart purchased the springs and began developing them for public use. The site was eventually incorporated into Kootenay National Park when it was established in 1920, and Parks Canada has operated the facility since 1922, making it one of the longest-running commercial hot spring operations in the country. Today, the facility is operated under Parks Canada and is open year-round, though hours may vary by season. ## Directions 1. From the town of Radium Hot Springs, BC, head east on Highway 93 (also known as the Banff–Windermere Highway) toward Kootenay National Park. 2. Continue approximately 2 km (about 1.2 miles) into the park. The road passes through the striking Sinclair Canyon — you'll drive between towering red rock walls. 3. The Radium Hot Springs facility is located on the right-hand side of Highway 93, just inside the park boundary. Watch for signage indicating the hot springs parking area. 4. GPS coordinates: 50.6235, -116.1542. *Note: A Kootenay National Park pass may be required for entry into the park, even if you are only visiting the hot springs. Passes can be purchased at the park gate.* ## What to Expect **The Pools** Two large outdoor pools await visitors: - **Hot Pool** — Maintained at a soothing 39°C (approximately 103°F), this is the main attraction. The mineral-rich water is fed directly from the natural hot spring source. The pool is large enough to accommodate many bathers comfortably and offers stunning views up the canyon walls. - **Cool Pool** — Kept at around 29°C (approximately 84°F), this refreshing pool is popular for swimming laps or cooling down between soaks. Many visitors alternate between the two pools, a practice said to invigorate circulation and open the pores. The backdrop of Sinclair Canyon's towering cliffs makes for a dramatic and memorable soaking experience, especially during golden hour or on a clear winter evening. **Facilities & Amenities** Radium Hot Springs offers a range of amenities beyond the pools: - **Spa Services** — A full-service spa is available on-site, offering massages and other treatments. - **Café** — A small café operates at the facility, perfect for grabbing a bite before or after your soak. - **Change Rooms & Lockers** — Modern change rooms, showers, and lockers are provided. - **Swimsuit & Towel Rentals** — Available for visitors who arrive unprepared. **Hiking & Activities** Kootenay National Park is a world-class destination for hiking, and Radium Hot Springs makes an ideal base. Popular nearby trails range from easy strolls — such as the Sinclair Canyon Trail and the Juniper Trail — to more challenging backcountry routes deeper in the park. Many visitors plan a morning hike followed by an afternoon soak in the hot springs. Other activities in the area include wildlife viewing (bighorn sheep are frequently spotted on the cliffs above the springs), cycling, and scenic drives along Highway 93 through the park. **Seasonal Notes** The hot springs are open year-round. Winter visits are especially magical — soaking in steaming mineral water while snow blankets the surrounding peaks is a quintessential Canadian Rockies experience. Summer tends to be the busiest season, so arriving early in the day or later in the evening can help you avoid crowds. **Admission** This is a paid facility. Admission fees apply and are set by Parks Canada. Check the Parks Canada website for current pricing and seasonal hours before your visit.
