Sycamore Reservoir Trail is a 8.6 mile moderately trafficked out and back trail located near Mt Lemmon, Arizona that offers the chance to see wildlife and is rated as difficult. The trail is primarily used for hiking and is best used from September until May.
Directions from Tucson: Drive up the Catalina Highway to the turnoff into the old prison camp beyond milepost 7. Turn left and follow the road either to a closed gate or beyond if it is open. Low clearance vehicles should park at the last building slab in the prison camp. Four-wheel drive vehicles with high clearance may continue the 1.25 miles to the trailhead.
This is a difficult hike. The last two miles going in are downhill over a lot of loose rock and boulders. Coming back up is difficult. There is a reservoir at the end of the trail but when you get there you will notice the smell of a sewer. It appears to collect all of the septic run off from Mt. Lemmon. Don't believe there will be usable water at the reservoir. I wouldn't feel safe even cooling my feet in the water.
This was a great trail that offered some great views of the catalinas. it was 2.8 miles and not 1.8. A friend and I back packed to the reservoir and set up camp for the night. really great spot
