The Big Hole Mountains rise to the west of Tetonia, the quieter, lower counterpart to the Tetons on the other side of the valley. Topping out around 9,800 feet at Big Hole Peak, the range is heavily forested with lodgepole pine and aspen, cut by creek drainages and dotted with old logging roads that now serve as hiking, biking, and snowmobile routes. It sees a fraction of the visitors of the Tetons across the valley.
Trailheads at Pine Creek Pass and Mahogany Creek offer good day hikes in summer. In fall, the aspen turn the slopes gold in late September, and the view east across the valley to the snow-dusted Tetons is one of the iconic sights of the region. Black bear, mule deer, and moose are common; grizzlies have been recolonising the range in recent years.
