It's just over 4.5 miles to Navajo Lake. From the trailhead (Photo #1), hike about 0.25 mile and pass the Groundhog trail junction - Photo #2. Stay right and hike through some meadows (Photo #3) before returning to the trees. At 9,500', cross a bridge (Photo #4) that spans West Dolores River and continue up a steep hill. Continue to 9,800' where the trail enters a large meadow - Photo #5.
Cross the meadow and continue through trees and more small meadows - Photo #6 and Photo #7. Near 10,700', hike up through a meadow and ascend several switchbacks to reach 11,000' - Photo #8 and Photo #9. Traverse east across the hillside and back into the trees to reach a junction with the Woods Lake trail. Stay right and descend a bit through the trees - Photo #10. Navajo Lake is about 0.5 mile from the Woods Lake trail junction. You now have a view of Gladstone Peak (13,913') to the east (Photo #11) and El Diente Peak towers above to your right. Within 0.25 mile of the lake, campsites start to appear along the right side of the trail. Reach Navajo Lake at approximately 11,160' - Photo #12 and Photo #13.
From the Lake it's about 2 miles to the upper, east end of the basin and the remaining routes to Wilson Peak and Mt. Wilson. For El Diente Peak, it's 1.5 miles to the point where the El Diente route leaves the main Navajo trail. Taken from above the north side of the lake, Photo #14 shows the route past the lake and Photo #15 shows the route to the upper end of the basin. Photo #16 is a closer look at some of the hike above the lake.
Pass the lake on the left (Photo #17) and pass through the bushes east of the lake. Nearly 0.5 mile east of the lake, leave the bushes/trees and hike northeast onto talus on the north side of the basin - Photo #18. Traverse east across this rocky hillside towards a headwall. Taken from above 11,700', Photo #20 looks back on the hike up from Navajo Lake. Continue up the left side of the basin as you approach the top of the headwall - Photo #21, Photo #22 and Photo #23. From 11,900', on top of the headwall, the terrain flattens out - Photo #24 and Photo #25.
If you're climbing the North Slopes route on El Diente Peak, your climb of El Diente starts off to the right. If continuing to Wilson Peak or Mt. Wilson, refer to those route descriptions. The Navajo trail continues all the way to 12,300' before turning left and ascending to the Rock of Ages Saddle, at 13,000'.
