This hike begins at the Taggart Lake Trailhead in the Grand Teton National Park. It's a great winter hike, as this trailhead is the farthest you can go inside the park before the road is blocked for the winter. The trail begins by weaving across a stream and heading up an incline up into the meadow. From there the trail is pretty flat across the meadow, providing beautiful views of the Tetons.
After the meadow, the trail splits. To the right you can head to Bradley Lake (an extra 2.5 miles added to the loop), or you can go straight to the left to Taggart Lake, making a nice 4-mile loop. The trail to Bradley Lake leads into a lush pine forest with views of Taggart Lake from above. The trail then weaves in and out of the forest until Bradley Lake appears on the right. Follow as the trail loops back to Taggart Lake and then back to the trailhead.
Note that snow and ice are common on this trail as early as mid-November.
