It is near impossible to find the Pima Canyon Trail Head if you haven't been there before... (no signage AT ALL). We didn't even know we were close as there was nothing to indicate where it was... which is a shame. However, it was well worth driving in circles for about 25 minutes to find the right street to turn off on. The trails themselves are well marked and clear... and the people along the trails are friendly. This place is a great place for a hike from anywhere from an hour to a whole day adventure.
