DIRECTIONS:
Hwy 55 toward Wilmington.
Get off at Wilmington exit #241.
Go west on River Road into the park and follow until it hits a 'T' at Blodgett Road.
Turn left on blodgett and go west to the stop at Kelly Road.
You'll see Julie's racetrack and Carpy's Cove bar on your left.
Turn left to go south on Kelly to the first parking lot on your left.
On the map, the parking lot is right where the three backwaters meet about halfway down Kelly.

Here is a link to a map of the place. (Darned Mapquest wouldn't let me copy and paste.)

If you are coming from the north, and don't care to backtrack, you can get off 55 at Arsenal Road and take the West frontage road south towhere it turns into Blodgett and simply continue on to Kelly. It's about the same time either way.
