It will be tough to beat the price ($6-12/person before taxes) at this Penobscot River Corridor campsite. Located just across the Golden Road from the Abol Bridge campground and before the bridge, Abol Pines is a state operated campground with picnic tables, fire rings, vault toilets, and a few sites with lean-tos. Millinocket is your last place purchase most forgotten items if you're coming from that direction, though there are a couple of smaller shops along the way. Be prepared to drive on gravel logging roads that can tear up your tires. Don't be surprised when the logging trucks start coming through in the morning.
I was here in early June, when rafting had started, but the Katahdin trails were not yet open. The campground was completely unoccupied. There are beautiful views of Katahdin from the bridge. This is NOT the Abol campground located in Baxter State Park. If you're paddling or rafting the Penobscot or planning an attempt on Katahdin, but couldn't get a spot within the park, this may be just what you need. Your noise experience will depend on your fellow campers as there isn't a host on site full time. May and June, prepare for black flies!!!
You'll park and then walk into the campsites. There was a little water on the road, but easily passable. The sites themselves were generally dry.
If you're from out of state with a few people in your group, it may be less expensive to book a site in a more formal campground.
