Lost Lake is a unique natural lake created by the San Andreas Fault and is fed by deep natural springs.
Although the lake has not been stocked with fish for many years, people still try their luck and toss a line in. Many visit the lake to picnic along the banks.
There are also opportunities for bird watching.
