Packsaddle Lake is a little-known gem tucked into the Big Hole Mountains west of Tetonia, Idaho — a small, cold, tree-ringed mountain lake with a rope swing, a hidden-away feel, and glimpses of the Tetons on the way in. It sees a fraction of the crowds of the more famous Teton-side lakes, which is a big part of its charm, but earning that solitude takes a rough drive and a steep little hike.

Getting there is the crux. The access road is genuinely rough — a high-clearance or four-wheel-drive vehicle is strongly recommended, and drivers of cars and minivans report needing some creative maneuvering to pick their way up. About 0.4 miles below the trailhead the road takes a steep, washed-out turn, and there are good pull-offs where you can simply park and walk the rest. From the upper trailhead it's a short but steep descent of around 300 feet in under half a mile down to the water; you'll spot the lake from the top of the trail, and switchbacks make the grade manageable.

At the lake you'll find a small camp area on the eastern shore and a rope swing out over the water — swing out far enough, since the lake shallows and drops off quickly near the edge, and the water is bracingly cold. It's a fun spot to swim, float (bring an inflatable if you can), picnic, and cool off after the hike in. Mountain bikers can also reach the lake by a longer, climbing singletrack from the lower trailhead that serves up beautiful Teton views before dropping to the water.

A few seasonal notes: the mosquitoes can be fierce up top in early summer (they ease off down by the lake), so bring repellent, and water levels drop as the season goes on. Snow lingers on the high road into early summer and returns in fall — more than one group has gotten a vehicle stuck in an early- or late-season snow squall up here.

The Big Hole Mountains that cradle the lake are a quieter, lower range just west of the Tetons, laced with trails and dotted with small lakes — a locals' playground for hiking, mountain biking, and hunting that rarely feels crowded. Packsaddle is one of its little treasures: a place to swing off the rope, float away an afternoon, cast for the occasional trout, or pitch a tent for a low-key overnight under the stars. On the drive and hike in, the reward is those signature Teton views rising to the east over the intervening ridges.

Come prepared for backcountry conditions: there are no facilities, so carry plenty of water, sun protection, and everything you'll need, and pack out all your trash. For those willing to brave the road, Packsaddle Lake is a rewarding, off-the-radar escape in the quiet Big Hole Mountains.
