Go Ahead, Take the Plunge!

Commonly referred to as “The Pool,” our Main Pool is an Olympic-sized mineral water pool fed by on-site geysers. Its Mission Revival-style buildings and its waters are historic—they were built in 1913 and replaced the original “plunge” from the resort’s earliest days.

Today, the pool is one of the largest in California and welcomes guests of all ages to swim and soak in hot mineral water that ranges in temperature from approximately 92–102 degrees Fahrenheit.

There’s a touch of Old Hollywood around the pool area, and you almost expect to see a starlet or two. An outdoor fireplace cabana lounge is located poolside. Floats, noodles, umbrellas, and chaise and deck chairs are provided.
