Best beach: Ogunquit---Cool town too: not far up the coast, kinda touristy, The beach stretches for miles with a brook that feeds from a marsh behind it.
Tides make acres of sand appear and vanish in a few hours. Sandy. I would go slightly early (Pre mid June) before NE schools let out for summer. 2 mile cliff walk south of town to a fishing village.
Best Light: Pemiquid (It is on the Maine qtr)...a little isolated, neat rock formations, good wildlife, inexpensive & picturesque.
Best Island: Monhegan: Take a shuttle out for a 45 minute trek to this Atlantic beauty: Trails, views, crashing surf, cranky locals:it is preserved, very few old vehicles Very historic.
Best Antiques: Belfast...do NOT try driving through on a Saturday!!
Best River for Kayaking: Androscoggin & Kennebeck
Best View: Cadillac mountain on Acadia
Best Museum: Augusta
This list will be altered again when I go up in June (for the 40th time)-renting a home not far from Acadia.
COOL story: After sadly packing up and driving out of Maine a few summers back we realized we were behind a Marylander on the Turnpike: We hit the toll booths down in NH and we followed them through it: ......THEY PAID FOR OUR TOLL!! How cool was that!
