Best Park in Maine - Okay, so I may be a little biased, but there are amazing mountains for all ability levels, the campground is gorgeous on many many acres. The swimming is perfect. Boat rentals reasonable. Nearby is Coos Canyon to jump off cliffs into mountain stream water. And the nature center is quite good . Movie night in the ampitheatre is always a highlight as well. NOT to be missed. And my personal favorite part is renting a boat to boat across the lake to have a quick snack on the deck of the Kawanhee Inn before boating back. And the rangers are lovely.
