18. Strawberry Park Hot Springs—Steamboat Springs, Colorado
On top of year-round, jaw-dropping views, the site for Strawberry Park brags 104-degree mineral water; a Goldilocks temperature in the range for hot-tubbing. That said, it’s a no booze allowed location too. Easy to overlook as the private pools of Strawberry Park are huge. Because it’s a private park, the property includes amenities like private massages, changing rooms, food concessions, and lodging. Oh yeah, and after dark, clothing is optional.
17. Grutas de Tolantongo Hot Springs—Hidalgo, Mexico
One can’t do much better than hot springs on the side of a mountain. In the state of Hidalgo, Mexico, named after the revolutionary leader Father Miguel Hidalgo, a milky blue river runs through the mountains. The river isn’t even the key feature of the park. Neither are the sweeping views of Mexico’s Sierra Madres. It’s the caves and pools carved into the side of a mountain that make this place something special.
