Central Park Tours Inc., New York

The friendly guides at Central Park Tours peel back the corners of the Manhattan landmark, showing tourists and native New Yorkers alike its many treasures during walking, bicycle, and pedicab tours. Throughout each educational jaunt around the lush 843-acre park, groups stop and learn about historic sites, such as the Belvedere Castle, Strawberry Fields, and the Shakespeare Garden, where the poet grew the tomatoes for his notoriously delicious BLTs. The company doesn't limit its knowledge of the area to just their tours. It also organizes special events, such as corporate gatherings, school functions, and even weddings, right there in the park.
