Glad to pass on any information! All routes are paved except Stud mill Road, the logging road. If you take Stud mill road, just be prepared for washboard roads and logging trucks to zip on by quickly; give them their space. Kanu in Old Town is a good restaurant, offering brunch on weekends.
Honestly, we love Maine for the coast; it’s where we spend our time while there. Our opinion is jaded, having lived on the Maine coast, bush Alaska, and traveled the country. Our oldest two are in college at UMaine; we got them an apartment that we also use as a home base when we’re not on the road. Interior Maine is beautiful but not very accessible to explore how we like, primarily private property, etc. We spend a lot of our time on MDI, Schoodic, and driving down US-1 exploring the different seaside towns when there. We would definitely recommend sticking to exploring coastal Maine for a quick weekend trip.
Not sure of any Overlanding type groups in the area. We set out on the road a few weeks ago to chase warmer weather; otherwise, we’d offer to show you around.
