Blackwoods or Seawall Campgrounds- Acadia NP

We stayed at Mt Desert Narrows RV Resort.

Park shuttle stops at the resort entrance. We used the shuttle to travel all over the park. We would get off at a trail head, then at the end of the trail we could catch the shuttle to our next destination. Worked great. Shuttle drivers were willing to provide a lot of info and history as we traveled.

Resort had a coin laundry which was convenient. Right on the water...great view.

I think Mt Narrows RV Resort is associated with 1000 trails?

The KOA is the best in my opinion, you can get a site on the inlet. Shuttle to town, clean.

I preferred Seawall. Much less crowded, less traffic. Great oceanside hiking trails and a beach. Thurston's lobster pound about 10 minutes away. Bass Harbor and Southwest Harbor 5 minutes away.

If you like tourism and shopping and being in the middle of things, Blackwoods is better. If you like relaxing, fishing villages, and less crowds, Seawall is better.

check their reviews on www.rvparkreviews.com under Maine, Acadia National Park. Neither have hookups.
Seawall is 35 minutes from anywhere.
Blackwoods has sites that will fit your RV and the shuttle stops there. I would definitely make reservations on www.recreation.gov. You can select 35' pull through site but not the exact site.
