Oak Trail has a footgolf course. Fort Wilderness has quite a few activities, some free some paid -- Tri-Circle-D ranch, pony rides, horseback riding, wagon rides, archery, fishing, bike rentals, segway tours, etc. I don't know if the canoe or kayak rentals have re-started or not. Keep in mind that reservations may be required to access parking at the Fort unless you arrive by WDW transportation.
