Pima Canyon

The trail is close to town (north of 1st Avenue and Ina Road) and goes out and back so you can hike as far as you want. Most hikers turn around at the dam for a 5-mile walk, about 4 hours for the leisurely hiker. You may miss the dam, a small structure and pond tucked into the west wall of the canyon. Beyond the dam the trail shows its lack of use and is rough and sometimes hard to follow. The trail gets steeper as you climb and has a few scrambles near the top. Count on a full day if Pima Saddle is your destination.
