Yes, you better climb it! The easiest route is on the other side of the mountain. It starts from Snowbasin where you can hike to it directly or climb Mount Ogden first and then traverse over the ridge between the two peaks.
The more interesting and fun route starts from this side of mountain seen in the photo. A hiking trail can be followed to the top of Malans Peak. From there you can climb up the west ridge of Allen Peak.
