Where to Fish Trio Lakes


Upper Trio Lake is a small (8.8 acres), remote glacial cirque lake located near the Idaho border in the North Fork Fish Creek drainage at 6,222 ft elevation. The lake lies on the Lolo National Forest (Ninemile Ranger District) in the proposed Great Burn Wilderness Area.

Size: 8.8 acres
Elevation: 6222 ft
Directions: The easiest way to access Upper Trio Lake is to take USFS Rd #250 (Trout Creek Road) from Superior, MT. From USFS Road #250, there are two options to hike. One option is to hike USFS Trail #171 to Heart Lake, then Trail #175 past Pearl Lake, to Trail #738. Hike southeast on Trail #738 ~ 1 mile to the saddle from which you can see Upper Trio Lake. Descend off-trail to Upper Trio Lake. The other option is to take Trail #738 (Stateline National Recreation Trail) east-southeast, along the Idaho border, from the top of Hoodoo Pass (USFS Road # 250) and follow the same directions from near Dalton Lake. Both routes are between 6 and 7 miles hiking distance, with moderate difficulty.
