Stack rock is located along the Boise Front, not far from Bogus Basin Ski Area. It is clearly seen from there and most of the Treasure Valley. As far as my understanding goes, it use to be on private property and hiking there was off limits until recently. It is now officially part of the Ridge to Rivers Trail system.

Getting There

Access is off Bogus Basin road, about 10 miles up the road. There is a turnout on the east side of the road, just as it turns right (driving up hill). More accurate mileage to be updated soon. From the road use trail # 120 Eastside trail to the junction with #124 Mr. Big / #125 Freddys Stack Rock Trail until you see the big rock. Lots of downed timber noted as of 04/2012 and I don't expect it to be cleared out any time soon...

Another way to assess the Rock it's self would be to hike up the ridge to the west at the trail junction at the top of the valley. There is no trail along the ridge. Follow the ridge as it turns north and continues to Stack Rock. Remain on the ridge top to stay on course.

Approx 6.5 miles and 1,700ft round trip.

Red Tape



The trail system is day use only although there are areas to camp. There is no water or camping facilities.


Primarily hiking and mountain biking on the trail to Stack Rock. Snow shoeing is also an option. While climbing to the summit of the rock would be possible, I have not located any documentation of it. I would think this to be a fairly easy trad route without any fixed bolts or anchors.


I will add pictures and more detailed information as I collect it. I just wanted to get the page under way. Please add any info that is relevant. Thanks!

The Ridge to Rivers trail map would be the most appropriate for the area, as the trail names and numbers are accurately documented.
