Just below the Briceburg Visitor Center is a parking area, restrooms, picnic area, and boat launch for whitewater river access. This gravel parking area serves as a meeting place for river trips, and a rest stop for Yosemite motorists. There is a great view of the Briceburg Suspension Bridge which was installed in 1926 and provides access to the north side of the Merced River and the BLM campgrounds downstream.

Popular activities here are gold panning/prospecting, fishing, picnicking, rafting take-out or put-in. It is a good place to meet and carpool downstream to other swimming holes in the BLM, Merced River RMA.
