From the lock house head one half mile upstream. Follow the sign to the trail head across the road. The trail to the Overlook Cliffs is 4.2 miles (about 3 hours) round-trip. There is no water supply and no restrooms on Maryland Heights. The trails include some strenuous uphill sections, but the reward is a spectacular view of the town and rivers below.
