The lake probably has interesting reflections now of the fall colors. Entering from Clopper Road (Rt. 117), take the road winding to the right around the lake, and park at the large parking lot at Kingfisher Overlook. A short distance from the parking lot to the right I think there is a large flat grassy area to paint with a view of the lake (or maybe walk further to see other views - the path circles the lake, a total of about 3-1/2 miles circumference).
The park opens at 8 a.m., and weekend admission at the gate is $3.
