This is such a cool trail. It actually loops around the entire town. Mammoth is so gorgeous, why wouldn’t you ride this trail? Not sure of the exact mileage, but it is a really good ride. It is uphill, downhill and flat. You get it all. It is mostly paved, some dirt spots and the rest you will ride in the bike lane in the street. There are signs every mile or so to tell you where you are and where you can go if you want off of the trail. This is a great trail for me to bring my dog in his little trailer that I tow behind my bike.
