Stack Rock lollipop loop uses the Stack Rock Trail starting at the parking lot at mile 13 on Bogus Basin Road. Stack Rock is a popular hike in the summer as it’s shaded by plenty of pine trees. True to its namesake, the top of the hill is a tower of boulders that offer spectacular views of the area.
Start the 11 mile run from the Stack Rock Trailhead off of Bogus Basin Road. Stack Rock Trail is an easy way to follow the trail up to Stack Rock and around the loop. The trail descends from the trailhead for a mile before it crosses Bogus Basin Rd.
The trail continues to drop for another 2-1/2 miles to a four-way intersection. Follow the sign to Stack Rock to start the loop on Stack Rock Trail.
Make the loop in any direction, but most run it clockwise, which is a steeper climb at 450 feet over the next mile. Spend some time at the top of Stack Rock to enjoy 360-degree views of Boise and the Sawtooths.
Follow the loop back down to the junction for 2.25 miles or use the Big Stack Cut Off and Mr.Big to get to the four-way intersection. Continue the way back to the trailhead via Stack Rock.
