What I Love NY + Visit PA doesn't tell you
Both state tourism boards cover their segments separately. The integrated multi-state Seaway Trail is the RV-traveler view.
Niagara Falls is the marquee tourist site but Wellesley Island State Park in the 1000 Islands and Stony Brook State Park near Dansville are quieter alternatives with similar RV camping quality.
