The Crandon Park is a park owned and operated by Miami-Dade County, Florida. The Crandon Park occupies the northern part of the island of Key Biscayne that lies between the Atlantic Ocean and Biscayne Bay. The park is connected to the mainland in Miami via the Rickenbacker Causeway. It is more than 800 acres (325 hectares) in size, and has two miles (3.2 kilometers) of beach on the Atlantic Ocean side. Crandon Boulevard extends from the end of the Rickenbacker Causeway through the length of the park, providing access to the Village of Key Biscayne and Bill Baggs Cape Florida State Park.

The park has a variety of facilities inclusive of a marina, a golf course, a tennis center, a family amusement center, picnic shelters and a nature center. Hardly, the parking is for more than 3,000 vehicles in the park. The part of the park is set along the Bear Cut Preserve, a designated natural Environment Study Area.

The land Crandon Park occupies was a part of the largest coconut plantation in the United States, operated by William John Matheson and his heirs. Latter, in 1940 the Matheson family donated 808.8 acres (327.3 hectares) of their land to Dade County (now Miami-Dade County) to initiate a public park. The county commissioner Charles H. Crandon promised that the county would build a causeway to Key Biscayne. Due to the World War II construction was delayed, but the causeway opened in 1947.
