Table Rock is the sandstone mesa that defines Boise's eastern skyline. At 760 meters above sea level and about 450 feet above the valley floor, it offers the best panoramic view of the city, the Snake River Plain, and the mountains to the north and east. The summit is accessible by a 3-mile trail from the Table Rock Trailhead off Warm Springs Avenue.
The mesa is the same sandstone formation from which the Old Idaho Penitentiary and much of 19th-century Boise was quarried. The geology is visible in the layered canyon walls on the approach trail, and the quarry cuts can still be seen on the western face. The hike up is not technical but is exposed and warm in summer — go early or late. The view from the top at dusk, with Boise spread out below and the Owyhee Mountains turning pink to the southwest, is one of the better free views in Idaho.
