Last summer we stayed at the KOA northen niagara/lewiston. It is a few miles (about 15 miles) from the falls. Nice area, it was a small KOA, not an over abundance of sites, but it was quiet., also close to Fort Niagara. There is the KOA on Grand Island, but, it was packed. There is also a $1.00 toll for going over the grand island bridge (toll booth on both ends). The bad part of the entire trip was the rain, it was the most western NY had in 144 years. The ground was swamp like.
