Have been to Promised Land, Hicory Run and Ricketts Glen. All the state parks are great but I believe that Ricketts glen has no hook ups where the other 2 have electric.
we camped at Pocono KOA. It was fairly close to Bushkill falls, shopping, and attractions. Considering the way the state parks are raising their rates, it was fairly competive. We still will be going to state parks irregardless of the price hike. They have entirely too much to offer.
Hope this helps!
