This trail starts out at the Battleship Rock, a 200 foot tall formation of welded volcanic ash, that also sports an impressive 25 foot waterfall if you take the short foot path from the north end of the picnic area. Follow the signs for trail 137, which will lead you from the base of the canyon where the East Fork of the Jemez River runs, steadily up the side of the canyon until you reach the popular McCauley Hot Springs. These springs are not very hot, so can even be an enjoyable dip in the summer - each pool is a different temperature, so be sure to try them all! Beyond the last pool of the hot springs, the trail continues upwards through pine forests, giving you views of the volcanic canyon below. Once you reach the Jemez Falls parking area, follow the signs that lead to falls viewing area. You can also take a small footpath, scramble down closer to the water. You could also do this trail as a one-way shuttle, if you park a car at the Jemez Falls parking area.
