At first glance, Morningside Park looks like the VIP room of open space. But don't let the arm gate and security guards fool you: It's available to everyone. Tucked away in what feels like a secret nook, a few happy joggers sweat next to a bay dotted with sailboats. The sun rises over the water while they heave — hearts fluttering — on a paved path shaded by trees. Women stretch on yoga mats as old Cuban guys fish next to rocks in the distance. Nearby, shirtless men do chinups on an obstacle course complete with monkey bars and balance beams. Three times around a winding, partially shaded, teardrop-shaped path is suitable for an easy Sunday morning jog. To push yourself, venture to the outside neighborhood, where cars are scarce and houses are colorful. Open from 7:30 a.m. until 9 p.m. weekends and 8 p.m. weekdays. Free parking.
