Devils Postpile and Rainbow Falls Trail

Access to the trail is primarily via the Reds Meadow Road. During peak season, a mandatory shuttle bus operates from the Mammoth Mountain Adventure Center, as private vehicles are generally not allowed past the monument's entrance station during these times. Parking is available at the Adventure Center. If the Reds Meadow Road is closed, accessing the monument can become a strenuous 17-mile round trip.

The trail offers varied terrain, including rolling sections and wide, sandy paths winding through a pine forest along the San Joaquin River. You'll also pass through an old burn zone now rich with wildflowers. Be prepared for some vertical gain throughout, and note that the path to the base of Rainbow Falls includes steep steps. Some sections, especially in the burn scar area, offer little shade.

You'll encounter two major highlights: the remarkable View of Devils Postpile, a geological wonder with 60-foot high basalt columns, and the majestic 101-foot Rainbow Falls, famous for the rainbows that often appear in its mist. The route also offers views of the High Sierra and the Ansel Adams Wilderness.

This route is rated as 'moderate' for jogging. While the overall distance is manageable, the rolling terrain and elevation changes, particularly the descent to and ascent from the base of Rainbow Falls, can add to the exertion. Summer conditions with heat, dryness, and altitude can also make it feel more strenuous.

The trail is best enjoyed when the Reds Meadow Road is open, typically from late spring to early fall. Visiting on a sunny day, especially around midday, increases your chances of seeing the famous rainbows at Rainbow Falls. Be mindful of summer heat and dryness, and plan accordingly with adequate water and sun protection.

If you drive in when the road is open to private vehicles, you will pay the entrance fee at the monument's entrance station.

Yes, the route also passes through significant sections of the John Muir Trail and the PCT - California Section H. You'll also find it intersecting with the Rainbow Falls Trail, Rainbow Falls Wagon Trail, King Creek Trail, and Fish Creek Trail.

Given the moderate difficulty, varied terrain, and potential for sun exposure, it's recommended to bring plenty of water, sun protection (hat, sunscreen), appropriate jogging shoes, and layers of clothing. Snacks are also a good idea for sustained energy. Don't forget your camera for the stunning views!

This specific route is generally considered an out-and-back trail, leading you to the Devils Postpile and Rainbow Falls before returning along the same path.

Beyond general trail safety, be aware of the elevation changes, especially the steep steps near Rainbow Falls. Summer conditions can be hot and dry, so hydration is crucial. The trail passes through an old burn zone, which means some sections may lack shade. Always be mindful of wildlife and carry bear-safe food storage if you plan to extend your stay in the wilderness area.
