Thornton Key Island Homesite & Waterfront Access | Lots 18 + 11 | 0.91 Acres. Create your own private island retreat on Thornton Key, a bridgeless barrier island along Florida's Gulf Coast. Lots 18 and 11 are offered together, encompassing approximately 0.91 acres and providing a distinctive opportunity to combine a residential homesite with waterfront access along Knights Pass Channel. Lot 18 offers a homesite for a custom island residence, while Lot 11 provides a route through the mangroves for a boardwalk leading to a private dock and boat lift. This combination offers buyers an opportunity to establish a waterfront lifestyle without purchasing the entire eight-lot assemblage (see 10049 Hel-Lew Ct. or MLS #C7522153). Accessible exclusively by boat, Thornton Key offers an appealing combination of natural surroundings, privacy, exceptional fishing, and access to some of Southwest Florida's most desirable boating destinations. Navigate into Lemon Bay, with connections to Stump Pass, Boca Grande Pass, the Intracoastal Waterway, and the Gulf. Located across the channel from Rum Bay Restaurant and near mainland marinas, dining, and boating facilities, Thornton Key combines the seclusion of island living with access to surrounding coastal communities. An ideal setting for your custom island home with private boating facilities, Gulf Coast sunsets, and exceptional fishing opportunities just beyond your doorstep. Lots 18 and 11 are also part of a larger eight-lot, 3.41-acre assemblage available for purchase. Additional property information and planning-level materials are available on request.
