Burning Springs Spa & Thermal Pools

Burning Springs Spa & Thermal Pools is on the lower level of the Marriott Niagara Falls Fallsview Hotel & Spa, on the site of a burning natural spring that was one of Niagara's first attractions. Outside, guests move through three thermal pools, hot, warm and cold, beside a Finnish-style sauna cabin and a fireside relaxation area.

Indoors there is a Himalayan salt sauna, a hot tub and a lounge. The $60 Oasis Pass covers both areas along with a robe, towels and a locker room with showers, and it is sold to guests without a treatment booking when space allows. Bathing suits are required, phones stay out of the spa, and guests must be 16 or older.
