The put in for West River is on Sunnyside rd off RT245 north of Naples. From Rochester we took 5&20 to where it intersects with Route 21. Take RT21 south and take a left on Parish rd then a left on 245. Take a left onto Sunnyside rd and the DEC access site will be on your left.
There is one point where the river comes to a T. The suggested route is to take a right at the T to avoid shallow spots and un-passable weed growth. The map shown shows where the turn is.
