There is basically no end to the great ‘workout’ hikes in the Santa Catalina Mountains – one fun option is a short loop using the Upper Green Mountain Trailhead, Green Mountain Trail, Brush Corral Trail, Brush Corral Shortcut Trail, Green Mountain Trail back to the Upper Green Mountain Trailhead.
Short with a nice bit of elevation, not very heavily used (for much of the loop anyway) and easily extended a few more miles to the Maverick Spring Trail or Guthrie Mountain. 4.5 miles, +/- 1500′ elevation gain/loss.
