Mallard-Larkins Loop is a 25 mile lightly trafficked loop trail located near Wallace, Idaho that features a lake and is only recommended for very experienced adventurers. The trail is primarily used for hiking, camping, fishing, and fly fishing and is accessible from July until September. Dogs are also able to use this trail.
The trail begins on Northbound Creek Trail 111. Head down the trail 2 miles (dropping about 1,400 feet) until you get to Sawtooth Creek. Cross the creek and follow Northbound Creek 4 miles (gaining 1,400 feet) until you come to Northbound Lake. Follow Trail 111 (0.5 miles) until it intersects Heart Pass Trail 65. Turn right on this trail to the ridge near Heart Lake. The junction to Heart Lake is 0.5 miles farther up the ridge, and the trail to Heart Lake is another 0.5 miles. To continue up the ridge to the high point, it is 0.5 miles past the junction to Heart Lake. From the high point, it is 0.8 miles to the junction of Trail 13 (if you decide to go to Crag Lake). Go 0.2 miles more to the junction of Trail 108, and turn right down this trail towards Mud Lake. Follow Trail 108 5 miles (losing 3,000 feet) down towards the Little Northfork Clearwater River (passing through a cedar grove). At the intersection of Clearwater Trail 50, go right (over the base of Mulligan Hump), and then 0.5 miles down to Sawtooth Creek. Cross the creek and follow the trail 0.5 miles to Surveyors Ridge Trail 40. Just after this intersection, the trail drops down near the confluence of Canyon Creek and the Little Northfork Clearwater River (to the trapper's cabin). Finally, to complete the loop, hike up Surveyors Ridge Trail to Sawtooth Saddle (8.5 miles), and back to your parking spot.
This trail was my first "real" backpacking trip, and was absolutely amazing! The forest was dense, the fly fishing was great, and the views were spectacular. If you have the chance to take this trip, by all means, do it! You will not regret your choice.
