Freddie's Stack Rock is an 11-mile trail loop, which is great for a hike or mountain bike ride. You'll get the very best view of Boise and the surrounding valley as well as crisp, clean air at 5,200 feet.
The trail to Stack Rock is a well maintained path that generates a lot of attention due to its special destination. The famed rock overlooks the City of Trees and surrounding Treasure Valley. This trek is popular among locals because of its proximity to the city and its spectacular views.
Getting There
From Boise, take Bogus Basin Road 13.1 miles to a small parking area just off of the road to the left. The trail begins from this parking area and the path is easy to locate below. Don't worry about getting lost, the trail is well-marked along the 11-mile trek.
The Trail
The trail is wide and accommodates mountain bikers as well as hikers and trail runners. The terrain is mild and generally flat until about half a mile from the destination. This last stretch is steep but most definitely worth the sweat—as you approach the rock protruding form the trees, you get to see how big this thing actually is. The higher you climb, the better the view you receive from both sides of the rock. Be careful, though—there are gaps in the rocks and it's not recommended to climb unless you're confident you can get up AND down.
Autumn is the prime season for this hike because of the vibrant colors and crisp, clean air. Snowshoeing in the winter would also be an awesome adventure.
