Tylers Bath Spring
Tyler's Bath Spring emerges at 92 degrees in the San Bernardino National Forest, producing water 30 degrees warmer than the ambient air temperature in high-altitude terrain where the San Gabriel Mountains rise sharply above the LA Basin.
A short walk from the parking area leads through mixed conifers to the spring at 3,100 feet elevation. The warm water emerges into a small rocky basin surrounded by pine and fir forest, offering a quiet alpine setting away from urban sprawl.
The spring sits within geologically active terrain where mineral-rich water heated deep underground rises through fractured rock. Historical use by local communities and Forest Service management maintains public access while protecting the natural resource.
The spring is easily accessible via a short walk from a nearby trailhead. Visit year-round, though winter snows may temporarily block access. The 92-degree water is suitable for soaking, and the surrounding forest provides scenic hiking opportunities.
