Table Rock Area
Table Rock Reserve offers challenging hiking and mountain biking opportunities. The Table Rock area offers stunning views of Boise and the Treasure Valley, and is a favorite among trail enthusiasts for sunset hikes and rides. Please note, the area should be avoided during wet, winter months as high clay content in soil leads to muddy conditions. Most access these trails from the Old Idaho Penitentiary parking log and trailhead, where there is a kiosk and directional signage for the trails.

This trail climbs steeply from the Old Penitentiary parking lot, to the top of Table Rock. It is an old road, so it is quite wide for the majority of its length. It is probably the most popular route to the top of Table Rock.
This trail starts by traversing the quiet backside of Table Rock, with expansive views of the upper Warm Springs drainage. The south side of this trail meanders beneath sandstone cliffs, affording sweeping views of the Treasure Valley and Owyhee Mountains in the distance before tying back into Table Rock Trail #15 for a nice loop opportunity.
This is a shorter and easier loop trail that leaves from the Old Penitentiary parking lot, and ascends the prominent point just to the west. It provides nice views for minimal effort.
The Shoshone-Bannock Tribes Trail #19A and the lower reaches of the Shoshone-Paiute Tribes Loop #19 have a compacted sand and gravel surface, allowing them to be firm and usable when most other trails are too muddy. These all-weather trails are great short hike alternatives for those times when much of the rest of the trail system is off-limits due to muddy conditions.
