Travertine Hot Springs
Natural geothermal hot springs near Bridgeport in California, known for mineral-rich water, travertine terraces, primitive soaking pools, and an Eastern Sierra setting.
Travertine Hot Springs is a natural geothermal spring area near Bridgeport in Mono County, California. Set against the dramatic landscape of the Eastern Sierra, the site is known for hot mineral water, colourful travertine deposits and a collection of primitive soaking areas shaped by both natural processes and long-term recreational use.
Unlike a developed thermal resort, Travertine Hot Springs remains a comparatively simple outdoor geothermal experience. The Bureau of Land Management manages the surrounding Travertine Hot Springs Area of Critical Environmental Concern, where recreation must be balanced with protection of natural and cultural resources.

Why Visit
Travertine Hot Springs combines three things that make a geothermal site particularly memorable: naturally heated water, striking mineral formations and a broad Eastern Sierra landscape. The springs emerge around terraces built from mineral deposits left behind by geothermal water. These formations give the site its name and create an environment very different from an ordinary swimming hole or constructed thermal pool.
Travertine is also useful for travellers wanting to understand California’s geothermal landscape beyond commercial spas. It is an outdoor natural hot spring where geology is visible almost everywhere around the water.
Bathing Experience
Travertine Hot Springs is a primitive natural soaking area rather than a maintained swimming complex. Water emerging from the geothermal system can be extremely hot. Historical geothermal data used by the Bureau of Land Management records Travertine Hot Springs at approximately 82°C, or 180°F. That figure should not be interpreted as the temperature of every soaking pool.
Water cools as it moves away from the hottest source areas and through the surrounding channels and pools. Conditions can also change with water flow, weather and alterations within the geothermal system. Visitors should therefore never assume that a pool is safe simply because other people are using it. Always test the water carefully before entering.
Location and Access
Travertine Hot Springs is located near Bridgeport in Mono County on the eastern side of California’s Sierra Nevada. The Bureau of Land Management identifies the springs as part of the Travertine Hot Springs Area of Critical Environmental Concern and manages recreational access through the Bishop Field Office.
Access is associated with the Jack Sawyer Road area. BLM mapping shows parking, trails, soaking tubs and different road-access classifications within the surrounding recreation area. Road conditions can change after rain, snow, freezing weather or periods of heavy use. Travellers should check current conditions before relying on an ordinary passenger vehicle.
Map note:
- Approximate geothermal spring coordinates: 38.2450, -119.2050.
- These coordinates identify the spring area and should not automatically be treated as the exact parking position.
- Access is from the Bridgeport area via local roads including Jack Sawyer Road.
- Check current BLM information before travelling.
Visitor Basics
- Natural geothermal hot springs near Bridgeport, California.
- Located in Mono County in the Eastern Sierra region.
- Managed by the Bureau of Land Management Bishop Field Office.
- Primitive outdoor setting rather than a commercial thermal resort.
- Short walking access from the recreation and parking area.

Entry, Rules, and Conditions
Travertine Hot Springs is managed as part of a sensitive public-land recreation area rather than as a conventional commercial attraction.
The Bureau of Land Management has undertaken recreation-management and habitat-restoration work at Travertine to improve visitor access while reducing damage caused by unmanaged recreation.
This includes defining authorised trails, rehabilitating unnecessary user-created tracks and managing parking and pullout areas.
Visitors should use established access routes, respect posted restrictions and avoid creating new tracks through the landscape.
Temporary closures can occur. Travertine Hot Springs has previously been closed to public access for Tribal ceremonial use, demonstrating why older travel information should never be relied on as proof that the site is currently accessible.
Access check: Before making a special trip, check the official BLM Bishop Field Office for current public-land information, restrictions, temporary closures and other conditions that may affect access to Travertine Hot Springs.
Spring Type and Water
Travertine Hot Springs is a genuine natural geothermal spring system.
Historical geothermal records list source water at approximately 82°C, or 180°F. This represents very hot geothermal water and should not be confused with the temperature of individual soaking pools farther away from the hottest source.
The water deposits minerals as it moves through the spring environment. Calcium-rich geothermal water can release calcium carbonate as conditions change near the surface, gradually creating the layered mineral material known as travertine.
These deposits can build terraces, channels and unusual textured surfaces around geothermal springs over long periods of time.
The combination of hot water and active mineral deposition gives Travertine Hot Springs a clear natural geothermal identity.
What Is Travertine?
Travertine is a form of calcium-carbonate rock commonly associated with mineral-rich springs, especially geothermal systems.
Groundwater moving underground can dissolve minerals from surrounding rock. When that mineral-rich water returns to the surface, changes in pressure, temperature and dissolved gases can cause calcium carbonate to precipitate from the water.
Repeated mineral deposition gradually creates layers, terraces, channels and crust-like formations around the spring.
These formations are part of the natural geological character of Travertine Hot Springs and should not be broken, carved or deliberately altered.
Safety and Etiquette
- Never assume a pool is safe based on appearance alone.
- Test water temperature carefully before entering.
- Stay away from water that feels excessively hot.
- Remember that the hottest geothermal source water can cause serious burns.
- Supervise children closely around geothermal water.
- Take extra care on wet, mineral-coated or uneven surfaces.
- Stay on established trails where directed.
- Do not damage travertine formations or alter natural features.
- Do not create new tracks or shortcuts across sensitive ground.
- Carry out rubbish and leave the area cleaner than you found it.
- Respect other visitors and the cultural importance of the area.
- Follow all temporary closures and BLM instructions.
Cultural and Environmental Respect
Travertine Hot Springs is more than a recreational soaking location.
The Bureau of Land Management manages the area for natural, recreational and cultural values. Management work has specifically focused on reducing damage caused by unmanaged recreation and protecting sensitive natural and cultural resources.
The springs also have continuing cultural importance for Native American communities in the region. BLM has previously temporarily closed the area to allow ceremonial use by a local Tribe.
Visitors should treat the landscape accordingly: use established access routes, respect closures, avoid damaging mineral formations and allow cultural activities to occur without interference.
Best Time to Visit
Travertine Hot Springs can offer very different conditions depending on the season.
The Eastern Sierra experiences cold winters, snow and freezing conditions, while summer can bring stronger sun exposure and hotter daytime temperatures.
Spring and autumn can provide more moderate conditions, but there is no single guaranteed best season because weather, road conditions and geothermal water flow can vary.
Winter travellers should pay particular attention to snow, ice and road conditions. After storms or wet weather, unsealed access roads may also become more difficult.
Before travelling, check current weather and BLM access information. Travellers approaching Bridgeport via US 395 should also check Caltrans US 395 road conditions, particularly during winter, after storms or whenever changing mountain weather could affect the journey.

Where to Stay Nearby
Bridgeport is the most practical nearby town for travellers visiting Travertine Hot Springs.
