Keystone Islands, North Miami, FL

Keystone Islands Neighborhood Overview

Overview

Keystone Islands is a distinctive and exclusive waterfront community located in North Miami, Florida, characterized by its series of private, man-made islands situated in the Intracoastal Waterway. The neighborhood is accessed via a single guarded gatehouse on Northeast 135th Street, offering a sense of seclusion and security while being just minutes from the bustling urban centers of Miami and Fort Lauderdale. Its unique geography, with canals and waterways separating the various islands—such as South Keystone Island, South Island, and South Bay Island—creates a serene, resort-like atmosphere where the water is the central feature of daily life.

The development of Keystone Islands began in the 1970s, transforming mangrove swamps into a premier residential enclave. Its design was visionary for its time, prioritizing waterfront access for nearly every property and fostering a tight-knit community oriented around boating and waterfront living. Today, Keystone Islands maintains a reputation as one of North Miami's most prestigious and sought-after neighborhoods, appealing to those seeking privacy, expansive water views, and direct access to Biscayne Bay and the Atlantic Ocean without the premium price tag of similar communities on Miami Beach.

Housing & Real Estate

The housing stock in Keystone Islands is predominantly composed of large, single-family homes, ranging from Mediterranean-style villas and Key West-inspired designs to modern architectural masterpieces. Properties are notable for their generous lot sizes, deep-water docks, and private boat lifts, catering directly to yachting enthusiasts. The architectural styles are diverse, though nearly all homes emphasize indoor-outdoor living with pools, sprawling patios, and panoramic water vistas. Given the exclusive nature of the islands, multi-family buildings and condominiums are virtually non-existent.

Real estate here commands a significant premium, with home prices typically ranging from the high $1 millions to well over $10 million for the most expansive estates. The market is almost exclusively owner-occupied, with rental properties being rare. Recent trends show sustained demand, driven by buyers seeking more space, privacy, and superior water access compared to Miami's coastal mainland neighborhoods. Property values are closely tied to waterfront footage, dock capacity, and renovation quality, with many older homes being purchased for land value and replaced with new custom constructions.

Schools & Education

Families in Keystone Islands are served by the Miami-Dade County Public School system. The designated elementary school is often the highly-rated Greynolds Park Elementary, while students may attend Highland Oaks Middle and Dr. Michael M. Krop Senior High School, known for its rigorous academic programs and International Baccalaureate curriculum. The specific school assignments can vary, so prospective residents should verify the latest district boundaries with the county.

Given the community's affluent demographic, there is also strong patronage of Miami's renowned private and parochial schools. Institutions such as Gulliver Prep, Miami Country Day School, and the Hebrew Academy are all within a reasonable driving distance. For higher education, the neighborhood is conveniently located near Florida International University's Biscayne Bay Campus and Johnson & Wales University's North Miami campus, offering both undergraduate and graduate programs.

Parks & Recreation

Recreation in Keystone Islands is intrinsically linked to its aquatic setting. The neighborhood itself functions as a private recreational haven, with residents enjoying boating, jet-skiing, fishing, and paddleboarding directly from their backyards. The protected canals and quick access to Biscayne Bay make it ideal for water sports and sailing. While the islands themselves are primarily residential with limited public green space, the community's focus is on private outdoor living.

Nearby, residents have access to several public parks. Oleta River State Park, located just north in North Miami Beach, is Florida's largest urban park and offers mountain biking trails, kayak rentals, and picnic areas along the Oleta River.
