When considering the Bronx, a number of landmarks come to mind—the , and Arthur Avenue foremost among them. But beyond those famed attractions, the borough offers several surprising urban oases—unexpected expanses where the bustle of the City is muted and life moves at a more languid pace. Two such places are and . The former is the largest recreation area in New York City; at 2,766 acres, it's more than three times the size of Central Park and features plenty of opportunities for outdoor adventures.

Traveling to the green space is relatively easy: take the 6 train uptown to the last stop—Pelham Bay Park—and emerge at the Bruckner Boulevard and Westchester Avenue intersection. Enter the southwest portion of the park there, or pick up one of a number of buses at the station that head in: the Bx29 runs north on Shore Road and then east on City Island Road, stopping twice in the park's confines; the Bx5 and Bx12 serve the golf courses and Orchard Beach; and Westchester's Bee-Line 45 bus will let you off in front of Bartow-Pell Mansion.Like some of the City's other natural areas, Pelham Bay Park's amenities include playgrounds, picnic areas, sports fields and running paths, along with bicycling and hiking trails, spots to kayak or canoe and even public golf courses and horseback-riding paths.

Built in 1901, the Pelham Bay course is better for beginners, with expansive fairways and a classic layout. Its more challenging sibling, Split Rock—named after a granite boulder that sits at the junction of the New England Thruway and Hutchinson River Parkway—is well suited for experienced golfers. And families with younger children will enjoy playing 18-hole mini golf at . More leisurely activities can be found on , the Bronx's famous stretch of sand. Dubbed "the Riviera of New York" after its opening in 1936, the 1.1-mile-long strand has a promenade, areas to picnic and prime views of City Island. Just to its north is the , a 138-acre salt marsh and forest nature preserve that features a rugged, New England–style shoreline. Here intrepid explorers can discover boulders deposited during the last ice age, an oak forest and a rare intertidal marine ecosystem.Those more interested in the area's past should make their way to , one of the oldest homes in the borough. Built in 1842, this grand edifice sits on a manicured 220-acre spot in the northern part of the park and affords a glimpse into 19th-century country life. The beautiful Greek Revival mansion and its nearby carriage house are open for public tours, and both are surrounded by gardens and hiking trails that stay open until dusk.History-minded visitors should also make a point of seeing City Island, where the borough's oceangoing past is always on display.

The is a popular spot, serving crustaceans in over a dozen different ways—sautéed, stuffed, broiled, baked or steamed, among them. Farther down City Island Avenue are and two waterfront spots, and Johnny's Reef, renowned for their fried dishes. Enjoy scallops, flounder, lobster tails, shrimp, soft-shell crabs, clams, oysters and squid, all served on paper plates, usually with a wedge of lemon. Johnny's dishes up an array of tropical mixed drinks amid its cafeteria-style decor; Tony's, right across the street and rebuilt after a fire caused by Superstorm Sandy, has similar liquid refreshments—and an arcade-style claw game with live lobsters in it.For a more formal experience, visit , where France native Stephane Kane and his wife, Maria Caruso, prepare Gallic dishes like escargots and coq au vin, or , where you'll find buttery lobster rolls (available at lunch only), mussels steeped in olive oil and garlic and a variety of steak and pasta dishes.If you've saved room for dessert, head over to to cool off with your choice of 20 ice-cream flavors, from traditional ones like chocolate and vanilla to sea-salt caramel.
