California’s Only Beach Hot Springs
As the closest natural hot springs to San Francisco, Marin Tidal Hot Springs can be found in a rocky grotto near Steep Ravine Beach during negative tides. It’s important to note that the geothermal vents at Marin Tidal are only accessible at low tides of -1ft or more. At all other times, the hot springs are submerged underneath the frigid waters of the Pacific Ocean. Once the pool is revealed you will only have a couple of hours to enjoy a hot soak before it fills back up.
FYI! Marin Tidal is AKA Steep Ravine Hot Springs and Rocky Point Hot Springs.
How do I find Marin Tidal Hot Springs?
To reach the hot springs you will need to hike down a vertically inclined trail from Steep Ravine Campground to Steep Ravine Beach. If the tide is low enough, the geothermal vents can be accessed from the north side of the beach. Make sure to wear sturdy shoes and be prepared for a sharp descent.
Once you reach the beach, you will need to look for a rocky cove marked by a large boulder. If your timing is right, the telltale sulfur smell of rotten eggs should be abundant. The water in the hot springs is usually about 100 degrees Fahrenheit, so be careful not to get burned. If the tide is exceptionally low you can actually dig your own pool in the sand near the mouth of Webb Creek.
