Why Live in Key Biscayne

Key Biscayne, Florida, is a barrier island connected to Miami via the Rickenbacker Causeway, offering residents stunning ocean views and abundant natural beauty. With a population of over 14,000, the area features a mix of Spanish Revival, ranch-style, and modern homes, along with condos, some of which are HOA-controlled. Key Biscayne is known for its higher housing costs, with median prices significantly above the national average. The island is home to several attractions, including Bill Baggs Cape Florida State Park, which offers fishing spots, trails, and the historic Cape Florida Lighthouse. Crandon Park, located on the northern edge, is popular for kayaking, sailing, birdwatching, and tennis. Crandon Golf at Key Biscayne provides an 18-hole layout with ocean views. Village Green Park in the island's center has soccer fields and walking paths. Dining options are concentrated along Crandon Boulevard, featuring diverse cuisines such as Italian-Argentinian fusion at Milanezza Kitchen and Bar, Mediterranean dishes at Costa Med Bistro + Wine, and Latin breakfast and lunch at Mestizo Latin Cuisine. Shopping includes boutique stores and a Winn-Dixie. Students attend highly rated Miami-Dade County Public Schools, with elementary and middle schools on the island and high schools in nearby areas. Key Biscayne faces hurricane and flooding risks, but homes are built to withstand severe weather. Metro Bus service connects the island to downtown Miami, and Miami International Airport is the closest commercial airport, 7 miles away. Crime rates in Miami-Dade County have seen a significant decrease, making the area safer than the national average.
