This is a short, close to Benson hike that can easily be done in about 2 hours.  The Trailhead is well marked with US Forest Service and National Park signage.  The parking area is in the Coronado National Forest.   Once you cross the fence at the trailhead you are in the Rincon Wilderness Area.  Hikers should be aware that there may be cattle grazing in the area around the trailhead.  There is a cattle watering site within sight of the trailhead.  The whole hike occurs in the Rincon Wilderness Area (part of the Coronado National Forest).  There are signs indicating that pets are not allowed.  The trail basically follows Miller Creek up to the boundary of Saguaro National Park.  This boundary is well marked.  Hikers wishing a longer hike can continue on into Saguaro National Park.  Much of the hike is easy, but it wanders back and forth across the braided stream.  This hike has numerous stream crossings.  Under normal dry conditions this should pose little problem because there are plenty of rocks for stepping across the water.  However, after rainy or snowy periods, the stream flow can be such that crossing is hazardous.  The vegetation for most of the hike is mixed oak woods with lots of manzanita.  Due the presence of water, there are usually plenty of birds along Miller Creek. 

The sign at the Trailhead indicates that the Saguaro National Park Boundary is 1.5 miles away.  When I did the hike and recorded it with my GPS unit the round trip measured 2.63 miles and took 2 hours including a 20 minute snack at the National Park Boundary.  The GPS unit recorded the Trailhead at 4239 feet and the National Park Boundary at 4505.  There is certainly some up and down on this hike and so it is safe to say that hikers will be climbing at least 300 feet vertically.   The last 0.2 miles or so is where much of the climbing occurs and trail has stretches with lots of smaller loose rocks that can produce uncertain footing for some people.  There are also logs to step over and places where the trail climbs up through boulders making for difficult footing.  So the trail is mostly easy, but there are a few short stretches that are moderate to difficult.  Overall, this hike is longer, but easier than the Rincon Waterfall hike.

The views available up at the National Park Boundary are pretty good.  But, the really great views, one needs to climb more up into Saguaro National Park.  See these views with the Rincon Peak Hike.  Other longer hikes can be accessed at this trailhead.
