Rainbow Falls in Mammoth Lakes is a stunning destination and definitely worth a visit. The falls, standing at 101 feet, got their name from the vibrant rainbows that often appear in the mist created by the cascading water. These rainbows are most visible around midday when the sunlight hits the water at just the right angle. The falls are part of the Devils Postpile National Monument, established in 1911 to protect the unique geological formations in the area.
However, be aware that driving to the falls is not permitted from 7 AM to 7 PM. Instead, you’ll need to take a shuttle from Mammoth Main Lodge, which costs $15 per person. The shuttle service requires some patience, as there’s a 30-45 minute wait each way in addition to the driving time.
Once you arrive, you have the option to explore both Devil’s Postpile and Rainbow Falls. The trail to Devil’s Postpile is a manageable 0.4 miles one way, while the hike to Rainbow Falls is 1.3 miles one way from the shuttle stop. Despite the logistics, Rainbow Falls is incredibly beautiful and makes the journey well worth it. If you plan accordingly and prepare for the shuttle wait, you’ll have a fantastic experience exploring these natural wonders.
