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.

We stayed for 3 nights in late July.   The campground is peaceful and quiet, with the sounds of birds and the trees being the main thing you hear - it is quite relaxing.   The trees are quite tall and create a lovely canopy overhead.   There is some road traffic noise, but it’s minimal.  The sites that face the marsh are the best sites - they have some grass and lovely views.  We were in site 5, which faces the woods and was dirt.  It had a slight bump in it which made hooking and unhooking our travel trailer a little difficult.   The sites are close together, and do not have any foliage buffers between them.  The bathrooms were very clean.   The people we met who worked at the camp were friendly and helpful.   It is within a mile of the Audubon center, where you can either put in your own kayak/canoe or rent one.   The Eastern Trail is 1.3 miles away,  and good for walking, running or gravel biking.
