From MT-1, follow the signs for Trail 44 along Twin Lakes Creek Road until it ends. The trail begins at the end of the road.

The area is largely second-growth forest, having been cut several times as recently as 20 years ago. Most of the trail is actually former logging roads. As you gain elevation, the forest will gradually shift from almost exclusive Lodgepole Pine to include White Spruce, Subalpine Fir, and Douglas Fir. During the spring and summer, wildflowers such as lupine, Indian paintbrush, and multiple lily species cover the disturbed landscape. Even though this is a restoration forest, there are still plenty of scenic vistas highlighting the Rocky Mountains of the continental divide.

After approximately two miles, the trail forks. Stay to the right and continue up gradual switchbacks. Along the side of the trail is a large pond or small lake, perfect for refilling canteens (be sure to filter it!). Another mile brings you to a more heavily wooded section of old growth.

The trail ends at Lower Fourmile Basin Lake, with an option to ascend a slightly steep 0.5 mile trail to the upper lake. Take some time to find a shady spot for lunch, cast a line, or go for a swim before heading back.
