Rainbow Falls is a popular destination for photographers, families and horseback riders, and it’s easy to see why: the 100-foot waterfall is one of the most grandiose waterfall sights in the Mammoth Lakes area. There are several ways to reach the falls: by walking a mile from Reds Meadow Resort or trekking the well-traveled two-mile route from Devils Postpile. All visitors ride a shuttle bus from Mammoth’s Main Lodge parking lot down into the valley floor (small fee applies).
