They have an amateur race every year too. It's usually in May, but I haven't heard about a date for this year.
Here it is - May 19th this year.
We have used them as well and they run a great operation. The race is May 19th, we are signed up already. The float from Peeler Bend to Lyledale is 4.5 miles and is a great float for kids. Water levels are an issue and are rain dependent. Here is a link to their web page:
Somebody please give a little more detail about the float. Are there places to beach the canoes and play in the water or do most folks just float straight through. I like to spend as much time on the bank as in the canoe when I go. Canoes are hard on my back.
There are plenty of places to stop and play/swim.
If he still does it another great option during the heat would be the Ouachita River from Remmel Dam to th Mavern whitewater park (Rockport). Every weekend during the summer they release. Saline River Canoes may still rent boats for that section.
