This is a wonderful place. I do this trip about once a month, since we live about 25 mins away. With the exception of a small tree down right before you get to the take out dock, but you can get over it without getting out of your canoe.
The state park now has a number of canoe's, but only two kayak's for rent. The kayak's are often out for repair. The cost is $15 for each each boat. They also have small flat bottom boats you can rent by the hour for the ponds.
You can camp at the state park or stay in one of the hotels in Aiken.
$2 per person to enter the park and $15 per kayak or canoe. This includes your life jackets and paddles.
Take 302 or 78 to state park road and look for the signs.
