Eighteenmile Creek (Burt Dam to Olcott) is a 2 mile trail located near Newfane, NY and is good for all skill levels. The trail is primarily used for canoeing and is accessible from May until August.
I did this trail a few times and most of the time it is pretty grown over and hard to do. We also did a hike and canoe trip, which was a lot more fun.
Mosquitoes, spiders, snakes, ticks... a riot of a trial!
