In this city of snarled traffic, high-rise apartment towers, and around-the-clock hustle, it can be difficult to find peace. Luckily, there are still at least a few green patches, like E.G. Sewell Park. The ten-acre Little Havana public nature park, named for an early-20th-century Miami businessman and mayor, is hidden so well even many longtime residents don't know it's there, tucked along the shore of the Miami River to the west of NW 17th Avenue. If you have little ones to look after, the park has an upper section with a playground and benches. If you're pining for something scenic, the lower section sits on the waterfront, the perfect hideaway in which to lounge on a warm afternoon. At Sewell, amid the chirping birds and soft river breeze, you'll forget you're only minutes from a traffic jam. Take a picnic and spread out on an expanse of some of the greenest grass in Miami, stroll under the soaring palms, and watch the boats glide by on their way out to sea. But most of all, relax — this is Miami, after all.
