You might confuse Gores Landing Unit WMA with the park just a quarter mile up the road from it, Gores Landing. Gores Landing, the park, offers fishing, picnic area, and amenities for only $5 per car with an additional $5 for overnight camping.
The Wildlife Management Area discussed here is purely for fishing, hunting, and of course hiking. Parking and entry are free, and the map below will get you there.
Gores Landing Unit WMA is part of the Cross Florida Greenway (Marjorie Harris Carr Cross Florida Greenway if you want to get fancy, but that is a mouthful!) and you can find various parts of that here. I strongly recommend using that site to find parts of the greenway, as Google Maps can lead you all over and to useless locations. This portion, the Gores Landing Unit, seems a portion only I have stumbled across to map and is not even listed on the Greenway site.
But it's wonderful. These trails through Ocala National Forest consists partially of old roads such as Coyner Road seen on the sign below, but they are now closed to motor traffic. I'm not sure the trails/old roads are maintained, but they are clearer and easier to follow than most you can find and quite wide.
Starting at the main trail head, veer right at the first break you reach in a small clearing, and it will lead you to a very nice spot along the Ocklawaha River. I saw plenty of fish in summer and spring, and the view is beautiful with bird sightings year around. There and back will take you just under 3 miles, and there are other trails to follow.
