Read this before you drive: Fairmont's pools are open only to overnight resort guests and members, 7am to 10pm, and no day pass is sold. Guests get a lot of water, with a 164 by 59 foot outdoor pool and a 128 by 45 foot indoor pool at 88-94 degrees, hot pools at 100-104, an adult soaking pool, a family soaking pool and a cold plunge around 65. The 350-foot enclosed waterslide, five stories tall, is closed through Thanksgiving 2026 while a pool renovation is finished. The indoor pools also close November 1-6, so check the dates when you book a room.
