South of Stanley in the heart of the Sawtooth Mountains, the 18 mile Toxaway Lake Loop begins and ends at Pettit Lake. The route combines the Pettit Lake Trail and the Yellow Belly Trail for an out-and-back loop.
The trail never drops below 7,000 feet, and its perfectly spaced chain of lakes means that you can find a campsite with a lake view every night of a three-day trip. Alice Lake, six miles in, is a good first stopover or turnaround spot for a day hike. The midway payoff is milelong Toxaway Lake, surrounded by jutting granite peaks.
To reach the trailhead from Ketchum, drive 43 miles north on SR 75, turn west on Pettit Lake Road, and follow signs to the trailhead in Tin Cup Camp.
Overall, Toxaway Lake Loop is the 1st most popular hiking trail of all 19 hikes in Idaho.
