Casa Blanca is a compact, established residential subdivision in Marathon, Florida, situated in the heart of the Middle Florida Keys. The neighborhood features a mix of single-family homes and duplexes, many constructed in the 1960s, offering a mix of affordable housing options in a desirable island location.

The community provides a peaceful, low-key lifestyle with convenient access to the Overseas Highway for travel to Key West or Miami. Residents enjoy proximity to the water, making it ideal for boating enthusiasts and those who appreciate the laid-back Keys atmosphere.

While lacking dedicated on-site recreational facilities due to its small scale and absence of an HOA, Casa Blanca benefits from its location near public parks and beaches. The surrounding area offers excellent opportunities for fishing, diving, and exploring the natural beauty of the Florida Keys.

Overall, Casa Blanca represents classic Middle Keys living—unpretentious, waterfront-adjacent, and free from the restrictions of larger planned communities. It is well-suited for retirees, families, or anyone seeking a slice of paradise without extensive community governance.
