Rare, private island with white, sandy beach in the Florida Keys offering exceptional development flexibility. Little Conch Key (also known as Walker's Island) is one of only two privately owned holdings on the island, located minutes from Marathon & Marathon International Airport, approx. 90 miles to Miami. The island is accessed directly from Overseas Hwy at MM 62 and is visible from Tom's Harbor Cut Bridge. The property consists of approx. 86, 183 sf. Or 1.98 Acres of uplands, 1.76 AC of environmentally protected land, and approx. 5.91 AC of owned submerged Atlantic Ocean bay bottom, offering hundreds of linear feet of water frontage, a deep-water boat basin, and concrete seawall. Ownership of bay bottom provides rare long-term flexibility for adding several boat docks and high-end Aqua Lodges. Zoned MU (Mixed Use), allowing for boutique hotel, restaurant, campground, or upscale RV park. The property includes 16 Monroe County transient licensed entitlements, a highly valuable and increasingly scarce asset. Opinion on file suggests the uplands combined with bay-bottom acreage may qualify for RV park development. Existing improvements include three elevated 2BR/2BA vacation rental cottages, approx. 826 SF each, and a concrete in-ground pool, providing interim use or redevelopment flexibility. Development potential includes luxury vacation rentals or Palatial single-family Home(s). Conceptual renderings on file for boutique hotel, restaurant, marina, boat docks, and luxury aqua lodges.
