Lost Trail Hot Springs Resort is located at the base of Lost Trail Pass on the Montana side, nestled in the beautiful Bitterroot Valley along Highway 93. The main attraction here is LT’s large, chemical-free hot springs-fed pool. Water temperatures are 94-95 degrees and 104-105 for the hot tub. The pool stays open year round, and gets covered by a dome in the winter. The pool’s depth reaches nine feet down, diminishing to a 10-inch wading area.
The resort is surrounded by Chief Joseph Pass’ 25 miles of beautiful groomed cross country trails. It’s just six miles north of Lost Trail Powder Mountain (nothing like a hot soak after an intense Powder Thursday), and snowmobiling access is readily available.
Enjoy a cabin or a stay in the Sacajawea & Meriwether Lewis Lodge overnight if you don’t feel like driving the hour-and-a-half back to Missoula, or get a ribeye steak at Lost Trail Resort’s restaurant and dine on the deck overlooking the pool.
Lost Trail Pass used to be an old Indian trail, climbing 2,000 feet in only three miles. For centuries, travelers have stopped at the quiet hot springs to rest before starting the long climb over the pass. You can, too.
