Steeped in lore and legend, the Beaverkill is the preeminent American trout stream. It is the river that made the Catskills famous as the birthplace of American fly-fishing. Very little public access upstream of Roscoe, but many places to get on the river below Roscoe. Many fly shops and guides in the area. Best to fish at off-peak times when you can find some elbow room. River supports a great wild population of trout, mostly browns, but also rainbows and brookies.
