Hilltop Hot Springs—often called “Whitmore Hot Springs” by locals—is a breathtaking natural geothermal pool located in the beautiful Eastern Sierra near Mammoth Lakes, California. Known for its warm mineral waters, panoramic mountain views, and peaceful atmosphere, Hilltop Hot Springs has become a favorite destination for travelers seeking relaxation, nature, and adventure.

Whether you’re planning a scenic road trip, a photography session, or a soothing soak under the stars, this guide covers everything you need to know about Hilltop Hot Springs: how to get there, what to expect, the best time to visit, rules, safety tips, and insider secrets.

What Are Hilltop Hot Springs?

Hilltop Hot Springs is a natural geothermal pool formed from underground volcanic activity in California’s Long Valley Caldera. The hot water travels through the earth, absorbing minerals before reaching the surface. To make soaking easier, a small man-made tub was constructed using rocks and cement, creating a warm, clean, shallow pool with a 360-degree view of the surrounding mountains.

The hot spring is known for:

• Clear, warm mineral water

• A great adjustable temperature (thanks to a PVC pipe!)

• Beautiful views of the Sierra Nevada and Owens River Valley

• Peaceful, uncrowded mornings and sunsets

It’s considered one of the most iconic hot springs in the Eastern Sierra region.
