My favorite part of the state is the area in the White Mountains around Big Lake and Crescent Lake and Mount Baldy. I've been going up there for over 45 years. I love the aspens and the variety of connifers. The following trail is a nice one. I borrowed the description from the site linked at the bottom of this post:
Arizona's White Mountains
West Baldy Trail #94
Elevation: About 9,000 feet at the trailhead and 11,200 feet at the Reservation boundary near the summit.
Season: May through October depending on snowpack. Sometimes snowdrifts block portions of the trail as late as June.
Use: Heavy from Memorial Day through Labor Day. Moderate at other times.
Length: 14 miles round-trip from parking lot at Sheep's Crossing.
Access: The trailhead is located at Sheep's Crossing, off the gravel portion of AZ 273.
The trail starts just out of the parking area and through the gate. Please, take a moment to sign the visitor register. The trail is easy to follow as it cuts across a wide meadow and edges up to the West Fork of the Little Colorado. The trail follows the stream for the next two miles, climbing gradually. This stretch is the most heavily used portion of the trail and quite possible the most heavily used trail on the Forest. If you have a problem with lots of other hikers, then avoid this trail on weekends and holidays. as the trail begins a more noticeable climb, the crowds thin out quite a bit. The trail crosses the West Fork over an old bridge and continues its uphill grade. The ascent is no vein-popper, but it can still be taxing due to the steady climb and high elevation.
The trail crosses meadows and winds through a thick forest setting dominated by spruce, fir and aspen. Beaver dams dot the stream and fishing on the West Fork is generally good. As you work your way up, the trail becomes a series of switchbacks. Please stay on the trail and resist the temptation to make your own shortcuts. This damages the soil, scars the land and causes erosion which could wash out the established trail and bring silt into the creek. The West Baldy Trail merges with the East Baldy Trail in a saddle near the Reservation boundary below Mt. Thomas. At this point you can see some new country and continue down to the other side, or turn around and see the trail you just came up from a different angle. Each is a 7 mile hike from this point. Many hikers park a vehicle at the Sheep's Crossing trailhead and another at the Phelp's trailhead as shuttle vehicles. The summit of Mt. Baldy is on the White Mountain Apache Reservation and is closed to all non-tribal members. Please respect their customs and laws and do not travel to the top.
