This is a small, bright and cheerful house overlooking Long Pond. A wood chip path leads down to a dock overlooking a pristine and extremely private portion of the lake. To say this is a good spot is an understatement--the location is incredible, at the end of a peninsula and surrounded by acres of woods. Our three kids (aged 13 and 10-year-old twins) swam every day in the warm water before and after all the many activities we did. Bar Harbor and Southwest Harbor are a short drive away and there's so much to do in every direction.
One thing that's not clear from the ad is that the owner's own house is set not too far away from the rental property. (She happened to be away during our stay.) That house has its own dock and is set far enough away so that it's still a private house rental, but just know that you're not entirely alone.
I've stayed on Long Pond before and I think this is a special house and amazing for families. Highest marks.
