There are a number of campground options when parking near the attractions up near Bar Harbor, Maine. The one we used last time there was Timberland Acres RV Park. Like almost all of the CGs up in that part of the country its very family oriented with amenities to fit family needs.
Out in the back section where we parked, the pull thru site was huge, level and roomy. We got a very generous military discount making it just that much more desirable for us. It was our home base for two weeks. Not mentioned in the CG web page is the fact that there is a super Wal-Mart less than a mile away. Just down the road a ways there is free parking for the free shuttles to Bar Harbor and Arcadia National Park. Also on the same road is the - must go to - Trenton Bridge Lobster Pound.
For the first day of our stay we had most of the back section to ourselves. Then they started showing up. Hitchhikers, we were surrounded by them. Over the next few days more than 40 of them showed up. They even had a Hitchhiker factory rep traveling with them. They were all part of a large Hitchhiker club from Texas and were staging up for a caravan tour of New Brunswick & Nova Scotia.
Here are some of the pictures we took. One was taken from atop Cadillac mountain and the other is of a four mast harbor tour boat (The 4 mast pix was taken from a high speed whale watcher boat. We were going hunting for Hump Backs).
Clicking on any one of them will start the slide show.
