We have stayed in a dozen or so rented camps around the ADK over the years -- we like to vary our location but spend a week every year one place or the other. Camp Lake Bear is the best we've ever stayed at, certainly the most well-kept and thoughtfully-appointed spot, and among the more unique locations.
The house is relatively new, except perhaps for the back bedroom, which looks like the original cabin. Everything is in really nice condition, and there are amenities we didn't expect (a full washer and dryer, the latter of which was indispensable when trying to dry out swim stuff). The hosts have really gone well above and beyond expectations for the little amenities: I honestly don't want to list them all, because I'd be spoiling what will be nice surprises for you.
The location: you get a lovely high-up view of the lake, but your own large (new) dock, plus a nice bonus terrace level halfway between the two. It's a less isolated area of the ADK (lots of boat traffic) but you're in close driving distance of supplies and hikes, and it's a tranquil summer community along the river/flow. There are a lot of steps, to be sure, so if that's an issue for you, take heed. But we rather liked having "zones".
There's a "quiet" bedroom in the back with windows on four sides, a full master BR, and a "kids" room with a split bunk.
I don't have enough room to go on, but I could! Thanks to our hosts and Higley the Bear for watching over us and taking such good care of a great camp.
