Maine is an awesome place to camp. North of Portland you can take Rt 295 to Brunswick, Me and catch Rt 1 which is the coastal route all along the coast. Bath is a nice place to visit as well as Boothbay Harbor. There is a nice campgrounds near Bath in Phippsburg called Meadowbrook Campgrounds and from there you can visit Popham Beach which is one of the prettiest beaches in Maine. The 2nd English colony was founded there in 1607 just after Jamestown. There are plenty of places to camp along Rt 1. Camden is very nice and Camden State Park is a nice little state park. Camden is pretty much a tourist town but lots of fun. If you are into hiking at all you can hike up the trail from the state park to maiden cliffs for an awesome view of Camden and the harbor. Continuing north, Bucksport has an awesome bridge with a viewing tower with breath taking views. There is also a Civil War Fort called Fort Knox which is a fun place to visit. Next is Ellsworth which is the gateway to Acadia National Park which is a must see but don't miss Northern Acadia Park which is near Winter Harbor. Many tourists miss this area and it's one of the prettiest parts of the park. There is a new campgrounds there in Winter Harbor near Fraziers Point that was just built a few years ago. Schodic Point has awesome views of Frenchmen's Bay and Cadillac Mountain. If you continue along Rt1 there is a campgound in Harrington called Sunset Campgounds which is very nice too. Just north of Lubec is Roosevelt Campobello International Park where FDR used to summer. You can follow Rt 1 right into New Brunswick thru Calais. If you go into Canada don't miss Fundy National Park and take a trip to Hopewell Cape to see the giant flower pots but go at low tide. The tide here is one of the largest in the world and the natural flower pot rock formations are awesome! Hope you have an awesome trip. If you have anymore questions about Maine msg me as I lived in Maine for over 30 years.
