I tend to go up the Old Trail and down the New Trail. The Old Trail is steeper and a good workout and the New Trail is gradual on the knees and easier to follow. The New Trail was created to reduce traffic where the trail is hard to navigate to reduce the impact hikers were making. Reflective signs are on trees to follow through the Old Trail sections. The trails merge before crossing into the alpine into the boulder field with good steps.

Mailbox Peak Trail ( new )
This new trail is gorgeous, especially the lower 2/3 rds where it seems a mini backhoe or trail building machine created a 4' wide nicely graded trail. The new trail meets up with the old trail about 1000 feet below the summit and climbs steeply from there.
