This is one of my favourite hikes in the Phoenix area. Not only do you have the backdrop of the Superstition Mountains but the trail ends at a series of pools which are surrounded by petroglyphs. The trail is uphill but the slope is moderate and the in and out distance is about 4 miles in total. I have hiked this in July, but the usual caveats apply. However, you are very likely to have the trail to yourself in the warmer months. Depending upon the time of year there may not be water in the pools but in any case this is special place which has clearly had significance for many many years.
There is a good variety of cacti to be spotted from the trail. I also understand that this can be a good trail to visit during the spring wildflower season.
Note that this trail is accessed from a parking lot situated on Cloudview Road. You’ll need a map or Satmap to find this but the first part of the trip is an easy drive east on US 60, past where the freeway ends with a left turn at a stoplight onto Kings Ranch Road (there is a Walgreens at the intersection).
Route finding on the the trail is easy with only one junction on route. Follow the sign north to hieroglyphic canyon.
