New York City's greatest treasure, Central Park is an expansive green space, 150 years old, that covers 843 acres and offers outdoor enthusiasts pretty much anything their hearts could desire against the dramatic backdrop of the city's architecture. Designed as a refuge for the cramped city in 1858 by Frederick Law Olmstead and Calvert Vaux, Central Park (lovingly maintained by the Central Park Conservancy) holds a special place in the heart of every New Yorker, from its horse-drawn carriages to its 136 acres of woodlands and the scenic views from the shores of its lake. Perpetually encircled by runners, cyclists, and rollerbladers, the park hosts big-draw events with its Center Park Summerstage series, Shakespeare in the Park, productions by the Metropolitan Opera and New York Philharmonic, and occasionally megaconcerts, like the one famously given by Simon and Garfunkel in 1981 that drew a crowd of 500,000. That is all just the tip of the iceberg. Beyond that, you can enjoy world-famous fountains (such as the iconic "Bethesda" at the lake and the Egyptian obelisk "Cleopatra's Needle"), placid gardens, ice-skating, the zoo, dinner at Tavern on the Green, the breathtaking reservoir, walking or biking tours, chilling out by the rollerskating dancers at the Skate Circle (endlessly entertaining), or simply tossing a Frisbee and catching some rays on any of the park's fantastic lawns (including the Great Lawn, Strawberry Fields, and Sheep's Meadow).
