Onion Valley Campground – Inyo National Forest

Onion Valley Campground is a scenic, high-elevation campground in the Inyo National Forest, located in the eastern Sierra Nevada Mountains near Independence, California.

At approximately 9,200 feet (about 2,800 meters) in elevation, it offers a pristine alpine setting tucked near the end of Onion Valley Road. The campground sits alongside a creek (Independence Creek), surrounded by lodgepole pines, aspens, rugged granite peaks, wildflower meadows in early summer, and nearby waterfalls.

Its proximity to the John Muir Wilderness and the Kearsarge Pass Trailhead (just ¼ mile away) makes it a popular basecamp for backpackers, hikers, and those seeking solitude in one of California’s most dramatic mountain landscapes. The campground typically operates from mid-May to mid-October, depending on snow conditions.

Detailed Amenities

Onion Valley Campground has 29–30 single-family campsites (some sources list slight variations), which are generally private with scenic views. Key amenities include:

  • Campsites: Picnic tables and fire rings/grills at each site. Sites can accommodate tents and smaller RVs/trailers (up to about 25–30 feet).
  • Bear Safety: Mandatory bear-proof food storage lockers at every site due to high bear activity. Bear-proof trash receptacles are also provided.

Grays Meadows Campground

Grays Meadows Campground (often referred to as part of the Grays Meadows complex) is a scenic campground in Inyo National Forest, located in the Onion Valley area of the eastern Sierra Nevada Mountains.

It sits at an elevation of about 6,100 feet along Independence Creek, roughly 6 miles west of the small town of Independence, California. The campground offers a beautiful mix of sunny and shaded sites in a high-desert landscape dominated by oak groves, with the dramatic peaks of Mt. Williamson and Mt. Whitney (the highest in the contiguous U.S.) providing stunning backdrops.

Lower Grays Meadows features 52 campsites (the overall Grays Meadows complex includes an adjacent Upper section with additional sites). It is popular with hikers, anglers, and those seeking a peaceful base for exploring the nearby John Muir Wilderness. The campground typically operates seasonally from late April through mid-October, though dates can vary with weather.

  • Pets are allowed (two per site, must be leashed).
  • Some sites are reservable via Recreation.gov; others may be first-come, first-served.

Activities

  • Fishing — Independence Creek is regularly stocked with trophy-size rainbow trout. The early trout season (starting in March) is a big draw.

  • Wildlife Viewing & Nature Appreciation — Abundant opportunities to observe local animals and birds.
  • Other — Picnicking, photography, mountain biking (on certain roads/trails), and relaxing by the creek. In spring, it can serve as a base for skiers and snowboarders accessing higher terrain.

Wildlife in the Area

The eastern Sierra location supports diverse wildlife:

  • Mammals — Black bears (common; proper food storage is mandatory), mule deer, mountain lions, pine marten, and pika.
  • Birds — Numerous species typical of the Sierra Nevada and high-desert transition zone.
  • Fish — Rainbow trout in Independence Creek, plus other native and stocked species.
  • Other — Occasional sightings of smaller mammals and reptiles. Raccoons are also reported by campers.

Bear safety is emphasized: always use provided lockers, keep a clean camp, and never leave food unattended.

This campground is ideal for those who enjoy a semi-primitive experience with easy access to town (Independence is about 15 minutes away) while being immersed in dramatic mountain scenery. Reservations are highly recommended during peak summer months. Always check Recreation.gov or the Inyo National Forest website for current conditions, fire restrictions, and availability.

Hot Creek Geologic Site

Hot Creek Geologic Site is located near Mammoth, Lake just off the 395 Highway in Mono County, California. The stream originates from Twin Lakes in Mammoth and continues on to Lake Crowley. The site is located near and a beautiful cold water stream which is located over a geothermal vent. Warm water is heated from a magma chamber located about three miles below the earths surface and bubbles up into the steam warming the water.

The Hot Creek does offer excellent fishing opportunities and popular among fly fisherman. Fishing used to be limited to barbless hooks.

No Swimming

The stream is now closed to swimming becuase “Earthquakes can cause sudden geyser eruptions and overnight appearances of new hot springs at Hot Creek.  Water temperatures can change rapidly, and so entering the water is prohibited. ” Reports of hot water geysers up to 6 feet tall in 2006 and rapidly fluctuating temperatures apparently caused the closure of the stream to swimming.

My grandfather used to point out that some hot water vents where not in the same locations as when he was a child. Perhaps, within my life the hot springs area has become too dangerous to swim.

J Rathbun

As a child and young adult, the stream was open to swimming and my family did this routinely on almost every trip. I recall active conversations about the possibility of an geyser eruption which would kill us and we understood the risk of swimming. However, we also understood the possibility of an such an event was very remote when one considers the geologic time tables.

Mount Whitney Fish Hatchery

Mount Whitney Fish Hatchery

Located just outside of Independence, Inyo County, California the Mount Whitney Fish Hatchery has played an important role in the preservation of the Golden Trout.  Beyond the hatchery’s primary purpose, the site makes an excellent location to pull off the highway, relax in the shade and enjoy a picnic lunch.  This is how I was introduced to the hatchery 30 years ago, and it is still much anticipated stop each time I travel the 395 highway.

The fish hatchery began life in 1915, when the town of Independence raised money for and subsequently purchased a 40 acre parcel of ideal land in Oak Creek.  Using foresight not seen in our time, Fish and Game Commissioner M. J. Connell directed he direct the design team “to design a building that would match the mountains, would last forever, and would be a showplace for all time.”  Charles Dean of the State Department of Engineering and the design time team decided upon a “Tudor Revival” architectural style.

Utilizing a budget of $60,000 the hatchery project was started in March 1916 and complete one year later.  The building was built using 3200 tones of  local granite quarried nearby, boasts walls up to three feet thick and features a Spanish Tile roof.  When the facility was brought online in 1917, the hatchery could produce two million fry per year.  

The hatchery’s design, led by Charles Dean of the State Department of Engineering, prioritizes durability and aesthetic integration with the landscape. The grounds, landscaped by a gardener from Golden Gate Park, feature lush vegetation and a large fish-rearing pond framed by the dramatic backdrop of the Sierra Nevada, evoking the feel of an old European estate. The main building includes a visitor center with a gift shop, a fireplace, and interpretive exhibits, while the interior showcases troughs for fingerling fish and historical displays. Additional structures on the 40-acre site include nine small residences and six commercial buildings, contributing to its community-oriented function.

The fish hatchery operated until 2008, when on July 12th a flood and mudslide tore down the Oak Creek watershed which in 2007 was burnt in a wild fire.  The resulting mudslide buried the fish rearing ponds, destroyed four buildings and killed the entire population of Rainbow Trout.

The pond offers some beautiful flowers in the spring.

Currently a restoration project is in process, however the fate of the hatchery operation remains unknown.
