The Pool at Calistoga Spa Hot Springs

"There are four different pools at the resort: an adults-only Jacuzzi pool in a gazebo; a heated soaking pool; a heated multi-lap pool; and a wading pool and waterfall for children"

"Great for families who jam the place on weekends, this motel-resort has slightly scuffed generic rooms (request one that's been remodeled) with kitchenette, and fantastic pools – two full-size, a kiddie-pool with miniwaterfall and a huge adults-only Jacuzzi"

"But once you step into the one of the property's four geothermal mineral pools, it won't matter – you won’' want to leave"
