Discover more about Rainbow Falls

Rainbow Falls, a majestic cascade of water plunging 101 feet into the Middle Fork of the San Joaquin River, is a crown jewel of the Devils Postpile National Monument near Mammoth Lakes, California. This natural wonder draws visitors from around the globe, captivated by the ethereal rainbows that dance within its mist on sunny days. The falls are not only a visual spectacle but also a testament to the powerful forces of nature that have shaped this dramatic landscape over millennia. The journey to Rainbow Falls is an integral part of the experience, offering hikers a chance to immerse themselves in the stunning beauty of the Eastern Sierra. The most popular route begins at the Devils Postpile trailhead, a moderate 2.5-mile hike that winds through the Ansel Adams Wilderness. Along the way, you'll traverse varied terrain, from open, sun-drenched meadows to shaded forests, providing glimpses of the surrounding mountains and valleys. Keep an eye out for local wildlife, including deer, marmots, and a variety of bird species. As you approach the falls, the roar of the cascading water grows louder, building anticipation for the grand reveal. The trail leads to an overlook perched above Rainbow Falls, offering a panoramic view of the waterfall and the canyon below. From this vantage point, you can fully appreciate the scale and power of the falls, as well as the vibrant rainbows that give it its name. The best time to witness these rainbows is during midday when the sun is highest in the sky. For those seeking a closer encounter, a steep, but well-maintained trail descends to the base of the falls. This descent involves navigating a series of stone-cut steps carved into the mountainside, adding an element of adventure to the experience. At the bottom, you'll find yourself on the banks of the San Joaquin River, directly in front of Rainbow Falls. The spray from the falls creates a refreshing mist, and the sheer force of the water is awe-inspiring. Many visitors enjoy wading in the shallow pools at the base of the falls, especially on warm summer days. However, it's important to exercise caution, as the rocks can be slippery and the current can be strong in certain areas. Swimming directly under the falls is not recommended due to the potential for falling rocks and debris. Beyond Rainbow Falls, the Devils Postpile National Monument offers a wealth of other attractions and activities. The Devils Postpile itself is a remarkable geological formation consisting of towering columns of basalt, created by the slow cooling of lava flows millions of years ago. A short, easy trail leads to the base of the Postpile, where you can marvel at its unique structure and learn about its geological history. Another popular hike is the trail to Lower Falls, a smaller but equally scenic waterfall located about a mile downstream from Rainbow Falls. The trail to Lower Falls meanders through a lush forest, offering a tranquil escape from the crowds at Rainbow Falls. The Lower Falls cascade into a series of turquoise pools, perfect for a refreshing dip on a hot day. Visitors to Rainbow Falls should be prepared for a variety of weather conditions, especially during the summer months. The days can be hot and sunny, but afternoon thunderstorms are common. It's always a good idea to bring layers of clothing, as well as rain gear, to be prepared for any eventuality. Sturdy hiking shoes are essential, as the trails can be rocky and uneven in places. And don't forget to bring plenty of water and sunscreen, as the sun can be intense at this altitude. During the summer months, access to Devils Postpile National Monument and Rainbow Falls is often restricted to shuttle buses, in order to reduce traffic congestion and protect the environment.
