Very difficult trail but very exciting. Bring some gators for your boots or you will get tons of pebbles in your shoes.
Saw some deer and mountain goats.
All in all great day and great workout. Don’t go unless you are physically ready because there are some brutal parts that test the muscles and psyche. Also difficult scrambling is involved towards the end for those faint of heart.

The trail (or more accurately, route) is only 2.5 miles each way, but what a 2.5 miles! Diamond peak is one of the three ultra prominence peaks in the state of Idaho, and at the summit you're provided views of Borah peak (and the rest of the Lost River Range), the Lemhis, Beaverheads, and the Tetons.

Approach the beginning of the route by taking Pass Creek road off of HWY 28, just before reaching Lone Pine. Shortly after turning onto Pass Creek road, you'll turn right (uphill) and follow that road as far as you can. You will need to pass through a couple of gates. Make sure you close them once you're through. A four wheel drive vehicle with good clearance is recommended.

The route itself is fairly obvious. You'll head up the shoulder and then follow the ridge on the East side of the mountain. Once you obtain the ridge, you'll be presented with some spectacular views of "The Riddler" to the Southwest (some of the most intense geologic folding you'll ever see). Getting up to the ridge involves a steady upward haul up loose scree. Once on the ridge, you're on solid rock.

In the last 3/4 mile to the summit, there are about nine pitches of class 3 scrambling with moderate exposure. One pitch is borderline class 4. In the hot summer months, the route should be devoid of snow or ice. If going earlier in the year, you probably should bring ice axe and crampons.

Early in our ascent, we heard a strange rumbling noise, and then spotted a large herd of antelope running across the mountain in front of us.

I'd recommend starting up the mountain early in the morning, as afternoon thunderstorms are not uncommon in the area, and you don't want to be anywhere on this mountain when they arrive.
