The last half mile of trail through a narrow spot in the canyon is rolling and rocky.

Fossil Springs Trail descends approximately 1400' over 4 miles to the springs for which Fossil Springs Wilderness was named. The trail starts off wide and smooth, but becomes progressively rockier as it winds its way down into the canyon. At approximately 4 miles in, a short, marked side trail leads off to the first springs source, where many hikers refill their water bottles. There are a few campsites near the creek (camp at least 100' from the creek) for about a quarter mile. The last half mile of the trail skirts along a steep-walled, narrow section of the canyon, offering no camping or access to the creek. The trail reaches the old Fossil Creek Dam at 4.75 miles, where the trail ends and meets Flume Trail.

Camping is prohibited at and below the Fossil Creek Dam for several miles down the canyon. The trail is in the Fossil Creek Wilderness. Bikes and mechanized vehicles are prohibited. There is no creek access for the first four miles of this trail. The trail is very exposed and extremely hot in the warmer months. Hikers should carry at least four quarts of water. The trail is very rocky. Hiking shoes or boots are strongly recommended.

Fossil Creek is one of two Wild and Scenic rivers in Arizona. A series of springs gush 20,000 gallons a minute year-round at the bottom of a 1,600 foot deep canyon, creating a lush riparian oasis rich with life. Over the years these calcium laden waters have laid down huge deposits of a type of limestone called travertine, creating deep pools for miles along the creek. The Wilderness and surrounding area are on the Tonto and Coconino National Forests, and are managed by the Coconino National Forest.

During the spring-summer season, camping is prohibited and a reserved parking permit is required to park at the trailhead.
