Great hike!!! Definitely go do this! Amazing views all around. Garmin watch tracked us 5.2 miles up and 5.2 miles back. Took a total of 6 hours with brief water and snack stops. Lookout tower at the top.

My group Hiked the trail to the campsite, set up camp, then hiked to the look out. We stayed the night and then hiked down. The trail was Steep but well maintained. It has been Recently cleared of fallen trees and debris. We recommend trekking poles for the trip, especially for the way back down. The snow at the camp pads is cleared away, but there is still snow along the ridgeline on the way to the lookout. Campsite is along the left side of the main stream.

We didn't make it to the top on account of rain, but we enjoyed the parts we did. Really steep, switchbacks. Great work out with beautiful mountain and lake views through the trees.

The trail is steep for the first two miles, and the switchbacks are seemingly endless during that time. Trail conditions are decent and the 5-6 downed trees are easily passible. The trail was free from snow below 5000ft, and the remaining snow at the top was easily navigated. The campsite was in good condition and the views were great from the top.

This is a strenuous hike. The trail is easy to follow however, as of May 2015 there is quite of bit of snow still on the mountain. This Trail is nothing but inclined switchbacks gaining in elevation. Gorgeous views as you make it up the mountain to the camp area where it opens up. B/c of the snow much of the trail was lost and we had to make our way on our own. Probably best to do this during the summer when you can follow the trail more easily! Coming down the mountain was a breeze.

The trail is steep the entire way and narrow in places. Switchbacks through trees for at least the first half of the trail which eventually opens up to meadow views of Diablo Lake to the south. Keep climbing to the top of the ridge for 360 views of mountain peaks as well as Ross Lake to the north. Not an easy hike, but the views are worth it.

Great views of glaciers peaks and Diablo Lake below. Not the best maintained trail, and not well marked. Difficult to find look out point. Steep incline the majority of the way.
