Los Banos Creek Reservoir
This is a view of Los Banos Creek valley, upstream of Los Banos Creek Reservoir. Spanish padres from Mission San Juan Bautista followed this creek on their way to the California Central Valley in the early 1800’s. Along this creek are historic "baths" where the City of Los Banos gets its name. Actually, there are more like deep pools in the creek rather than baths.
To get here, use a boat to go to the upstream most area of Los Banos Creek Reservoir. From there follow a hiking path along the south bank of the creek for some time (1.5 hrs?) This picture was taken from a hill on the south side of the creek where it exits a narrow canyon.
Otherwise, it would be possible to hike from the park entrance to this location, though it would be a long hike.
The best time to go is early spring before the grass dries out (early March?).
California State Parks leads guided hikes (March–April) to this point, lead by an intern. I was once that intern.
