Overview:
If you want easy hikes in the west part of Saguaro National Park (Tucson Mountain District) then you can combine two easy trails to get the most out of Saguaro National Park - the Valley View trail and Wild Dog trail.
Valley View is an easy and popular trail along the Hohokam Road (unpaved). Wild Dog is also an easy hike across the Hohokam and Golden Gate road.
Tips:
Bring lots of water during summer time. It's much cooler to hike during the winter. However, you want to be there in the spring for the flowers.
