Mountain biking

The Volcanic Tablelands loop offers a distinctive mountain biking adventure through an ancient volcanic landscape near Bishop. You'll navigate dirt roads and doubletrack across broad tuff plateaus, enjoying expansive views of the Owens Valley framed by the Sierra Nevada Mountains to the west and the White Mountains to the east. This moderate 22.7-mile (36.5 km) route involves 1185 feet (361 metres) of elevation gain, typically taking around 3 hours and 13 minutes to complete.

To plan your visit, note that the trail is easily accessible from Bishop, with parking available at spots like Happy Boulders Parking. Spring and fall are the best times to ride, offering comfortable temperatures for this exposed route. Always carry plenty of water, as services are limited once you're on the trail.

What truly sets this ride apart is its unique geological history, shaped by a massive volcanic eruption over 700,000 years ago, creating an almost alien landscape. Keep an eye out for ancient petroglyphs scattered throughout the Tablelands, adding a fascinating cultural dimension to your ride. The area is also a renowned bouldering destination, so you might spot climbers enjoying the eroded rock formations.

Chalk Bluff

Highlight • Natural Monument

Chalk Bluff, for which the road is named for, is remarkably a straight, ~5-mile-long, escarpment that forms the south edge of the Volcanic Tableland. Named Chalk Bluff for its light tan-to-white colored, chalk-like rocks, they stand in contrast to the darker, volcanic Bishop tuff boulders that stand atop the escarpment and are popular with rock climbers. The Owens River flows below the Chalk Bluff with the gravel road running between, all making for a truly unique riding experience.
