People are often surprised to learn of the variety of high-altitude conifers that exist in the Central Highland region of Arizona. Cool north-facing slopes and canyon bottoms in the northern Bradshaw Mountains support a rich diversity of both plants and animals. The Isabella Trail traverses through stands of pine, oak, Douglas fir, aspen, and white fir in a 700-foot climb to South Spruce Ridge. At several points along the way there are some grand views of the highest peaks in this mountain chain—Mt. Union and Mt. Davis.

The Smith Ravine Trail travels under an almost continuous forest canopy of ponderosa pine and Gambel oak, and consequently, has plenty of shade but few good viewpoints. The trail is designed with few steep climbs, so is an excellent horseback or mountain bike route. The lower trail is about four feet wide with a smooth tread. The Smith Ravine Trail climbs from Walker Road for about 800 feet in elevation to its junction with Spruce Mountain Road (Forest Road #52A).

During 2006, portions of this route have seen forest thinning and the cutting of trees killed by the 2003 bark beetle infestation. But from the upper portion of the route there are still wonderful views of the Prescott basin and a sweeping panorama of grassland and forest landscapes that stretch to the volcanic mountains near Flagstaff. It also offers an intimate view of the west side of Thumb Butte.

Two trails in one, this is a hike for everyone. Offering a close-up look at some of the most spectacular scenery in all of Yavapai County, a lush riparian community of willows, sycamore and cottonwoods within the Watson Woods Preserve borders the southern end of the trail. As Watson Lake comes into view, watch for bald eagles, waterfowl and shorebirds. Once past the lake, the trail cuts through a dramatic landscape of rocky granite spires before finally heading out into open rangelands to the north.
