What to See and Do
Hiking and Biking
Mt. Williamson Trail
Located in Inyo National Forest, the Mt. Williamson trail is one of three 14,000-foot summits in the area. This challenging route usually takes 18 hours to finish, and you won't find many other people on this very hard trail. The best season to attempt this is March through October. Don't bring your dogs; they're not allowed here.
Distance: 25.4 miles round trip
Difficulty: Strenuous
Fishing and Boating
Sabrina Lake is about 20 miles out of Bishop. You can rent boats here. There are vault restrooms. The busy season is July and August. Fishing is permitted, but fish cleaning isn't. There is a fish-cleaning station close to the boat shop beside the lakeshore trail. Boat moors usually open by Memorial Day, but several years of California drought have impacted lake levels. Call ahead for reservations. Motorized boats are permitted, as are car-top boats, kayaks, and canoes. The available species of fish varies each year depending on water levels and what local fisheries stock the waters with.
Climbing
Climbing is popular in several areas near the Inyo Mountains undeveloped area. You can find many climbing opportunities in the nearby Inyo National Forest. There are also bouldering areas around the Chalk Bluff and Buttermilk areas under the jurisdiction of the Bishop Field Office. You can look up and find "BLM camping near me" in dispersed recreational areas. Contact the local ranger station for fire regulations available at the time for Bureau of Land Management campgrounds. Campers and climbers should know that camping is only allowed on public land; climbing areas here are intermixed with private and utility lands.
Wildlife Viewing
There are certain endemic animals you'll only find here and nowhere else. In fact, you might not even see some of them while you're here unless you plan very deliberately. The Sierra bighorn sheep is probably the most notable animal, but the black toad is also a relatively local phenomenon. The golden trout, Lyell salamander, and slender salamander are also species you might see at various points that you're not likely to back home.
Picnicking
You have nearly unlimited options about where to picnic in Inyo Mountains. There are many side roads splitting off the main highways, so you can find lots of scenic sites to enjoy open valleys or even canyons. Since the Sierra Nevadas to the west soak up a lot of the rain, the weather here is usually pretty clear. However, it's also arid, so keep fires to fire rings or metal fire grates in select locations.
Stargazing
Inyo Mountains and anything up and down the Owens Valley are great places to see the actual Milky Way galaxy with your own naked eye. Light pollution prevents one-third of all human beings from seeing it where they live, and over three-quarters of North Americans live in urban areas where it's not possible. Population density here is so low that it is possible, especially thanks to clear weather from being in the "rain shadow" of the Sierra Nevadas.
Off-roading
The Swansea-Cerro Gordo OHV route is 34.7 miles of trail looping in the area of Lone Pine, California. This moderately challenging off-road driving route has an elevation gain of over 8,000 feet. Always brace for traffic due to the popularity of this area for off-roading. You can bring your dogs along, and some areas even permit off-leash time. Be sure to check out the Cerro Gordo Ghost Town when you pass by.
