Do Not Attempt to find this from I 690. It is illegal and dangerous to do so. Access to posted parking is off the I690 West ramp for the Amphitheater, through boating access parking down a short paved road (speed limit 15 mph). Park there and enjoy the medium walk to this cache container. No Night Caching. Trails are closed dusk to dawn.
