Bear Gulch Reservoir, reservoir in Woodside, California, USA

Bear Gulch Reservoir is a small lake in Pinnacles National Park in California, situated in a valley surrounded by steep rock cliffs. The water remains still and reflects the surrounding cliff faces, while a dam constructed in 1935 holds back the water and helps prevent flooding in the area.

The reservoir was built in 1935 by the Civilian Conservation Corps during the Great Depression. This project was part of a nationwide effort to improve the landscape and protect the region from flooding.

The reservoir takes its name from the surrounding valley that was recognized by early local inhabitants. Visitors today often sit by the water to enjoy the quiet, showing how this place serves as a peaceful retreat in an otherwise dry and rocky landscape.

Access is via the Moses Spring Trail, a well-marked path about 1 mile from the parking area to the reservoir. The terrain is moderate to walk, so wear sturdy shoes and bring plenty of water, especially during the warmer months when the sun exposure is greater.

Near the reservoir are talus caves with natural rock passages and stairs that wind through the underground. These caves are home to Townsend Big Ear Bats and close seasonally to protect wildlife during sensitive breeding periods.
