This is a fun trail to hike, easy with interesting variations with the vegetation. The Marshall Gulch side is very open with some trees and a little creek. The Aspen Trail is true to its name. Beautiful aspens everywhere, nicknamed it the Aspen Forest. There are some young trees growing on both trails, as Summerhaven had a fire some years back. Would still highly recommend these trails. There are connecting trails to these trails if you want to go further. Lots of people and parking is limited. If you park on forest land, make sure you pay the $5 fee as we saw a park ranger giving out tickets when we were there. The fee box is where the trailhead is located. Wonderful hike, picnic areas and Mt. Lemmon has many hiking opportunities.
