Gunnison Route Trail is a 2.2 mile moderately trafficked out and back trail located near Montrose, Colorado that features a river and is only recommended for very experienced adventurers. The trail offers a number of activity options and is best used from April until September.
this route is the easiest route to the river from the rim. However, most would find it extremely hard. At one point you have to use a chain to assist in getting down and back up. I did it out and back in one day. If I did it again I would camp at the river and return the next day. Great backpack camp at the river's edge.
