Corey Hill Park

"Just off busy Beacon Street, is a park high atop Corey Hill with extraordinary city views that make it perfect for a picnic. You can also watch the runners and cyclists who use the hill for interval training, or take the kids to play on the playground at the summit. You'll likely have it mostly to yourself, so no one will see you when you give into the temptation to roll down the grassy hill, which is fringed with oaks and maples."-http://mysecretboston.com/do/high-life
