Lyell Glacier can be reached by climbing, and be prepared for a challenging ascent. The time required is between one or two days. Three of the routes you can take are the East Arete, the most direct route in high snow years, the Lyell-Maclure which will be a Class 2 to 3 climb, and Glacier Direct, the chute to the right of the summit.
Hiking to great vantage points to view Lyell Glacier Yosemite National Park can be done if you don’t want to do a more challenging climb. Take the John Muir Trail along the Tuolumne River from Tuolumne Meadows. This part is easy and only becomes a more moderate hike when you approach the Donahue Pass.
If you get a permit, you can do overnight camping in the wilderness. A good place to camp is in the partially forested upper part of Lyell Canyon.
Yosemite Lyell Glacier was discovered by John Muir as he explored the region. Since 1883, the glacier has retreated about 70%, splitting into two smaller glaciers in the mid-1900s.
