One of my familys all time favorite places to hike. Letchworth Park is large and beautiful with stunning views of numerous falls and lovely river gorge. There are many trails in this park and a wonderful place to camp, take a hot air balloon ride, geocache, hike, cross country ski, white water raft... etc.
My girlfriend and I did the white water rafting at Letchworth. It starts from near the Lower Falls and goes to St. Helena's. I was totally at ah just viewing the Gorge from another way. If you ever get a chance to do this. I say do it. Go to Adventure-Call Outfitters website; they are the ones that do this there.
