"Finding Nirvana is like Locating Silence" Jack Kerouac- Dharma Bums
Cinnamon is one of two mountain passes on the Alpine Loop (the other being Engineer Pass) that connects Ouray-Silverton-Lake City. Cinnamon is on the southern part of the loop and is the easier of the two. You can find all the information about this 4x4 trail over at TrailDamage's site.
The loops has sections that are both flat and wide as well as narrow and winding. If you have reservations I would recommend starting on the east side of the loop (Lake City) so you can turn back if you decide you're not up for it.
This a super popular destination for wildflowers that also gives you access to the 14er Handies Peak.
This GPS route for Handies starts below American Basin and goes straight through it..
