Bishop, a small town in California’s Owens Valley, has become one of the best known bouldering destinations in the world. Two of its main areas, the Happy Boulders and the Sad Boulders, are canyons cut into the Volcanic Tableland just north of town, on public land managed by the Bureau of Land Management. The rock is unusual, the setting is wide open, and the rules are simple once you understand why they exist.
Rock made by an eruption
According to the BLM, the Volcanic Tableland was created about 750,000 years ago by a cataclysmic eruption of the Long Valley Caldera, which laid down the Bishop Tuff. Over time, water cut small drainages into that volcanic layer, and the walls and boulders left behind are what climbers use today.
Tuff climbs differently from granite or sandstone. The surface is covered with pockets, edges and knobs, often in steep overhangs, and the friction feels grippy when the weather is cool. Skin wears out fast, so plan rest days.
Where they are
The BLM places the Happy and Sad drainages along the Inyo and Mono county line, about 7 miles north of Bishop. Both canyons run north to south, opening onto the Owens Valley. From the area you see the crest of the Sierra Nevada, which the BLM puts at 14,000 feet, about 16 miles to the south-west, and the White Mountains, about 11 miles to the east.
How to get there
The BLM describes two routes from Bishop to the Happy Boulders parking:
- From Main Street (US 395), take the junction for Highway 6, turn left onto Five Bridges Road, then left onto Chalk Bluff Road. Follow Chalk Bluff Road for 2.3 miles to the parking area.
- Or continue north out of Bishop toward Mammoth, turn right onto Pleasant Valley Dam Road, pass the county campground, then turn right onto Chalk Bluff Road and drive about 3.6 miles.
The Sad Boulders are reached from the same Chalk Bluff Road. Check a current guidebook for the exact parking, as the road is unpaved in places.
Why the area is managed
The BLM tells a short history. In the early 1990s, the Tableland was visited only by local climbers. By the late 1990s, thousands were coming from all over the world. With that increase in use, the BLM and the local climbing community developed a climbing management approach that protects the land while keeping it open to climbing.
The area sits where the Northern Mojave and Great Basin plant provinces meet, so it holds plants and animals from both. The BLM describes the environment as fragile and slow to recover. Every new trail and every crushed shrub stays visible for years.
How to climb here without causing problems
- Use the established trails and the existing landing zones under each problem.
- Do not move rocks or dig to improve a landing.
- Brush off chalk and tick marks when you finish.
- Carry out all trash, including tape and food wrappers.
- Keep groups small and voices low. Sound travels a long way in a narrow canyon.
These habits are what keep access open in a place that went from a local secret to a world destination in a single decade.
The season
The Owens Valley is high desert, at the meeting point of the cold Great Basin and the hotter Mojave, as the BLM puts it. Bouldering on tuff is best in the cool months, roughly late autumn through early spring, when the rock feels sticky. Summer afternoons are hot and the friction disappears, so most climbers head to higher areas or come back at dawn. Winter can bring cold snaps and the odd snowfall, but sunny days in the canyons are often comfortable.
Bishop as a base
The town of Bishop has gear shops, groceries and places to stay, which makes it a practical base for a week of bouldering. The two canyons sit close to each other and share the same volcanic rock, but each has its own character, and guidebooks describe them problem by problem. Many visitors spend mornings in one and afternoons in the other, following the shade.
What to bring
- At least one crash pad, and two if you plan to try tall problems.
- Plenty of water. There is none at the canyons.
- Sun protection, even in winter.
- A brush and a skin care kit for the sharp tuff.
Other bouldering in the Bishop area
Bishop is also known for the Buttermilks, large granite boulders west of town at the foot of the Sierra. The rock and the style there are different from the Tableland, and many visitors split their trip between the two.
