The Banff Upper Hot Springs water is geothermal, coming from the earth’s crust 3 km down and makes for one of the best places to relax those stiff muscles after a ski day. Just be warned, afternoons can draw a crowd in the summer, so head there in the morning or late evening for a quieter experience, otherwise you might feel like you're in a giant adult bathtub. How much are the Banff Hot Springs? Don't worry - it won't break the bank at just over $16.
