Soda Springs, Natural spring in Tuolumne County, United States

Soda Springs is a natural spring in Yosemite National Park where carbonated groundwater flows to the surface. The site shows visible mineral deposits and formations that have built up over time from the steady flow.

Soda Springs takes its name from the carbonated mineral water that surfaces in Tuolumne Meadows at 2,622 m. Indigenous Americans used the area before John Muir passed through with grazing sheep in 1869. In 1885 John Baptiste Lembert filed a homestead claim here, and in 1898 John McCauley used the homestead as seasonal pasture for his livestock. The Sierra Club built Parsons Memorial Lodge beside the springs in 1915.

The name Soda Springs is often used for the log cabin built over one of the springs, the Soda Springs Cabin, listed on the National Register of Historic Places on 19 April 1979. The springs rise at 2,622 m in Tuolumne Meadows, near the Tuolumne River, and park authorities advise against drinking the water.

Soda Springs lies at 2,622 m in Tuolumne Meadows, near the Tuolumne River, reached by a short trail from the Lembert Dome parking area off Tioga Road. Tioga Road is usually open only from late spring to autumn, and snow can linger into early summer. The water is not safe to drink.

The water flowing from the ground is naturally carbonated, created by geological processes deep beneath the surface. This phenomenon is uncommon and reveals the active geological forces working beneath the Sierra Nevada mountains.
