Walk toward the lake on the access road until you approach the dam at the southern end of the lake. Cross over the dam and watch for some blazes that will guide you round the lake. The trail stays pretty close to the shore of the lake but may be hard to find. Continue looping around the lake until you are back at the dam. Walk back to your car.
