Look carefully, or you'll miss the circle of benches at the back of the Mastick Pavilion, a mini-park just south of Puritas Hill and the Valley Parkway intersection. You'll see the pavilion, the horseback riding trails, and the swings, but it's easy enough to glance right over the concrete wading pool tucked in between. With its little fountain and gently sloping concrete floor, the pool is a summer favorite with families who know the Rocky River Reservation well. At dusk, it takes on a romantic feel. Splash around and play awhile.
