Yea, its beautiful. There is another SP in MD very much like Cowans Gap when it comes to the lake, trail, and beach. Greenbrier SP near Hagerstown. We do usually enter Cowans Gap the way you suggested...turning onto the access road off route 30 at the peak of the chain there. That drive alone is worth the time. When up there Friday that area still had 4-8" of solid, full snow cover.
