About Radium Hot Springs
The Radium hot springs emerge in Sinclair Canyon at the south entrance of Kootenay National Park. The water comes from the rock at about 45°C and fills two pools: the hot pool for soaking and a cooler pool for swimming. The name comes from early 20th-century tests that found traces of natural radioactivity in the water, at low levels.
The pools sit beneath reddish rock cliffs in a mountain setting. The Ktunaxa and Secwépemc peoples used the springs long before Europeans arrived. The current facilities, run by the park, have been refurbished several times since the 1920s.
Bathing is popular after a day of hiking or driving, and in winter, with snow around, the temperature contrast feels even more striking.
