The boat launch area in Alton is, as you know, right in the parking lot near the Alton Town Docks, but you cannot park your boat trailer there. You may launch your boat, tie up at the docks, and then take your trailer down to the "Letter S Road". Take a left out of the parking lot onto Rte 11 heading east. Follow Rte 11 past Parker Marine like you are heading up to the village of Alton. Right at the base of the hill going up into the village is a road that turns off to the right(the Merrymeeting river runs right next to the road). that is the Letter S road. Follow it down and you will see a parking area across from the Town Highway Dept. Facilities. The area is marked for Boat trailer parking. (I'd bring a good lock). Then you can take your truck back down to the bay to park. Total drive is about a mile each way. No charge for parking, first come first serve. (the Letter S Road, if you continued down it would bring you out to Rte 140 at the Alton Central Fire Station. Hope that helps.
