From Travel + Leisure:

Nestled between Los Angeles and San Diego is an oasis that many Californians might have forgotten existed: a hot springs resort built around geothermal waters. Murrieta Hot Springs Resort isn’t new — in fact, it dates back to 1902 — but it has been closed to the public for 30 years.

The grand reopening, which is slated for February 2024, will welcome visitors back with more than 50 geothermal pools, water features, and cold plunges set across 46 lush, landscaped acres. The ancient alkaline geothermal waters, which are touted for providing pain relief and a sense of well-being, once gave the resort a nationwide reputation. The natural hot spring water hasn’t changed, but the property will debut a fresh new look and amenities.
