No, there is no direct walking path that connects Disney's Fort Wilderness Resort & Campground to Disney's Polynesian Village Resort. These two resorts are located on different bodies of water; Fort Wilderness sits on the shores of Bay Lake, while the Polynesian is situated on the Seven Seas Lagoon. The distance between them is several miles, separated by dense woods, canals, and busy bus roads that are not designed for pedestrian traffic. To travel between them, the most "Disney" way is to take a boat: you would take a "Blue Flag" water taxi from Fort Wilderness to the Magic Kingdom entrance, and then transfer to the Monorail or the Gold Flag boat to reach the Polynesian. Alternatively, you could take a bus to the Magic Kingdom and then transfer. Walking between resorts is generally only possible within specific "hubs," such as walking between the Contemporary, Polynesian, and Grand Floridian via the Seven Seas Lagoon loop, or walking between the Epcot-area resorts. For a trip from Fort Wilderness to the "Poly," you should budget at least 45 to 60 minutes for transportation.
