The Peace Creek Trail starts by crossing many small creeks that feed into Peace Creek which make the beginning of the trail very lush. In Springtime, this trail is lined with wildflowers. The first 2.5 miles are very mellow with lots of little creek crossings and then the trail ascends on a south facing hillside. You'll ascend for a while and then finally get a break to catch your breath on.
Look around as you climb and take in the large rock formations all around. Finally, you'll enter pine forests and sagebrush hillsides and climb steeply towards the ridgeline. All of the trail is rideable until the first saddle. From the first saddle to the summit there are a couple lose sections. Many sections of the trail offer views of Peace Rock and the surrounding mountains and valleys.
Now, the trail will stay perched on top of a steep ridge until you come to the side trail to Tranquil Basin. If you have time, head out to Tranquil Basin, it is a large meadow with an amazing stream meandering down the meadow. After the trail junction you'll ride along Habit Creek down to Deadwood Reservoir.
There are lots of ride options from this trail, including an out and back, or turning the ride into a much larger loop.
