Trail Route Description

Passage 6 rolls across the foothills of the Santa Rita Mountains. The trail passes through oak-lined, semi-desert grassland and features ocotillo, barrel and prickly pear cactus. The terrain is up and down over rolling hills and across several ridges and sandy washes. There are a few short, steep climbs followed by similar descents, with an overall downhill trend. 

This section features grand vistas to the west and views of the Empire Mountains to the east. Looking south, Mountain Wrightson dominates as a majestic reminder of where you have been. Look north, however, and you will see the mighty Rincon Mountains, which foretell adventures to come!
