Rainbow Falls
Highlight โข Waterfall
It is located in Devils Postpile National Monument near Mammoth Mountain. The national monument protects Devil's Postpile, an unusual rock formation of columnar basalt. Devils Postpile National Monument encompasses 798 acres. In addition, the John Muir Trail and Pacific Crest Trail merge into one trail as they pass through the monument. Excluding a small developed area containing the monument headquarters, visitor center and a campground; the National Monument lies within the borders of the Ansel Adams Wilderness.
About 75,000 years ago, lava erupted from a vent just east of the present-day Falls. The eruption occurred in two stages. The first pulse of lava flowed about 1 kilometre (0.62 mi) westward and pooled in the Middle Fork of the San Joaquin drainage. The second pulse of lava insulated the first, allowing it to cool slowly and to fracture vertically. The layer above cooled under different conditions and fractured horizontally. Geologists describe these rocks as platy rhyodacite and are visible in the cliffs that surround Rainbow Falls.
As water rushes over the cliff, it erodes the vertically fractured rhyodacite more easily. A small cavern begins to form at the base of the Falls, and the overlying rock loses its support and collapses. This process, known as undercutting, causes the waterfall to recede slowly upstream. To date Rainbow Falls has retreated about 500 feet (150 m) due to undercutting.

Highlight (Segment) โข Natural Monument
Permits for Fish Creek AA14 must be obtained online or at Inyo Forest Service Visitor Centers upto 6 months in advance. If ordered online, must be picked up latest by 9 am on the day of the hike at the Mammoth Lakes Welcome Center. (recreation.gov/entranceDetails.do?contractCode=NRSO&parkId=72203&entranceId=315396)
The road to Reds Meadow and Devils Postpile is closed in winter. Backpackers visiting in winter must be prepared to ski, snow shoe or hike into the Reds Meadow Valley. Usually from the last week of June, vehicles can enter at night and be parked at the trailhead. However, during daytime hours one must park at the Adventure Center and take a paid shuttle bus (ca 30 min).
Mountain elevations in this area traditionally have ice and snow until late June or early July.
Fish Creek trail follows the general route of an old wagon trail. Starting near Reds Meadow Resort shuttle stop # 10 or the Rainbow Falls trailhead shuttle stop #8 the trail passes multiple junctions with the John Muir, Devils Postpile and Rainbow Falls trails. The Fish Creek trail follows Crater Creek to the Fish Creek Valley. Beyond Iva Bell Hot Springs, the trail goes to Cascade Valley and eventually connects to the John Muir and Pacific Crest Trails near Purple Lake or Tully Hole.
This is an active bear area; check food storage maps on the USFS Webpage for where you must use bear resistant food containers to secure food and trash. fs.usda.gov/recarea/inyo/recreation/hiking/recarea/?recid=20502&actid=51
If done as a sidetrip from the John Muir Trail near Reds Meadow, it is about 12 miles to Iva Bell with a drop of 1,500 ft and then a climb of 1,000. To rejoin JMT after the Springs, continue about 5 miles and climb 2,700 ft. The first section south of the JMT on Fish Creek Trail can be exposed and hot and passes thru a burn area. Total mileage is similar to staying on the JMT, but there is more elevation change.
There are at least 6 well maintained pools, and several others, created by visitors over the years to enjoy the water from the many hot sources on the slope at the end of the valley. Best way to find the Springs is to notice warmer runoff as it crosses Fish Creek Trail.
Do not camp right next to a hot spring pool.

Nelder Grove is a truly unique place: Along a nice selection of easy to moderate hiking trails, you will visit the largest concentration of giant sequoia trees within the Sierra National Forest. There are 54 mature trees like Bull Buck. There are also pioneer cabins and old giant sequioa stumps to explore in this area. The area was named for John A. Nelder who came to California during the California Gold Rush in 1849 and built a cabin close to the grove's largest tree. Unfortunately, the cabin burnt down in a fire with Nelder inside.
