RV Parks in the Adirondacks

A friend is looking for recommendations for RV campgrounds in the Adirondacks. She's been looking in the Keene Valley and Blue Mt Lake areas specifically, but recommendations outside those areas are also welcome. They'll be renting an RV and driving up from Delaware.



Her youngest daughter is also hoping to swim in/near/under a waterfall during their trip. Any suggestions on that front would also be appreciated!
