The Bar Harbor KOA delivered what it promised, but I am not sure we’d return.  The staff was very friendly and helpful.  They deliver nicely bagged firewood and have daily garbage pickup.  The bathrooms were clean and camp store well stocked.  The Island Explorer bus for Acadia stops at the campground.  There are rv, tent, and cabin options.  Our waterfront site was terrific - gorgeous view, and we could launch our kayaks directly from the site.  The fire pit was big and sturdy.  There were great sunrises and sunsets.   The location is an easy drive for downtown for Bar Harbor, North East Harbor and South West Harbor.

My challenge with the KOA is the sites were so close together.  Everyone was really packed in, with no buffer between sites.  The 339 - 342 sites were literally bumper to bumper.   It is a very busy campground.   If  you are looking for privacy, this is not the place to go.
