I have never hiked this whole loop--but I've done the two ends of the trail. Putt-Putt (Cache Creek end) is a favorite local "in-town" trail. The Gros Ventre Wilderness abuts the town of Jackson and this trail is within that designated wilderness area. Unfortunately, the trail is close enough to town that it is heavily used by hikers, dog walkers and mountain bikers--so it doesn't feel like you are alone in the wilderness. BUT, it is such a treasure to be able to quick hike so close to town in such a beautiful valley. There are a huge variety of wildflowers starting as soon as the snow melts and depending on how much rain we might get in June, extends into July. Even if you only have 1 hour for a walk--this is the place to go.
Game Creek is similar, but is south of Jackson about 5 miles. It is not as heavily used and the wild flowers are equally beautiful--also perfect for a quick hike.
I suspect mountain bikers (I am not one) really enjoy doing the whole loop.
