To get to the trailhead, you'll need to find your way to Mayberry Drive in west Reno. Whether you are heading west, coming from McCarran or East, coming from 4th Street, you'll turn south on Plateau Road. This winds uphill for a ways, with only a few side streets leading off, until you reach a right onto Woodchuck Circle.
Taking this right, you'll find a small parking area - and depending on the time of day and day of the week, a few cars already lined up there.
The beginning of this section of the trail is pretty obvious. There's the parking area, some signage, the ditch (with differing amounts of water depending on the season), and...
For the first two thirds of a mile, the trail winds past the backyards of some pretty impressive homes. It can feel a little intrusive to be here, but please respect people's privacy and this section goes by quickly.
Before long, the trail passes out of the neighborhood and into National Forest land. Now, because of the meandering nature of the ditch and the trail, it seems like you're always either entering or leaving National Forest of City of Reno land or something. You get used to seeing these signs and ignore them after a while.
The trail dips into gullies and ravines, then heads back out to crest around the shoulders of hills. Here's the trail heading out of a ravine, back into the morning sun.
Just some photos of the scenery here -
At one point, you come around a bend to see an industrial area spread out in front of you. The large building at the top center is the Patagonia warehouse.
There is another access trail heading up from near the Patagonia warehouse - it's pretty steep, and I haven't gone in that way in a while. Here's where it meets up with the Ditch trail, though -
At just under four and a half miles from the trailhead comes the turnaround point. Here the trail leads off to the left and dead ends at a hole in the side of the hill, out of which rushes the water that flows in the ditch. (In the spring, anyway. Tends to taper to a trickle in the fall.)
You can get pretty close in to this, but be careful - footing is precarious. And it wouldn't be fun to do those four and a half miles back in wet shoes.
The trail does continue from here - off to the right or straight up a hill, as you approach from the east. It no longer parallels the ditch, though - although it may meet back up with it at some point; I haven't been out past this.
From here, you can retrace your steps back to the trailhead. If you were out as early as I was on this day, you may actually see some other people venturing out on the trail at this point.
So there's another one of Reno's favorite running trails. A nice, easy one, with no hills at all - and an out and back, so you can bite off as much of it as you want to. Enjoy it!
