Jay to Farmington Rail-Trail is a 14.5 mile point-to-point trail located near Jay, ME and is rated as moderate. The trail is primarily used for mountain biking and is accessible year-round.
I road this trail this spring on a semi-cool day. Leaving from Farmington you'll get the sense that it will be a reasonably easy, although fairly long, rail-trail ride. And for the first few miles you'd be correct but be forwarned, although there is no real technical difficulties in completng this 14+ mile ride to Jay, you will run into a few miles of sand. I do have to say, I was happy I was in pretty good shape, my legs were tired by the end of my return trip. Now, I am a 50+ male riding on a 15 year old mountain bike, so put that into perspective if you ride this trail.
You'll find some nice scenery along the way but nothing breathtaking. I will ride this again next summer, thins time spending more time condition my legs in the gym.
