Mammoth Scenic Loop

Embark on the Mammoth Scenic Loop, a moderate racebike route spanning 15.8 miles (25.5 km) through the Inyo National Forest. You will experience a rewarding ride with 1224 feet (373 metres) of elevation gain, typically completed in about 1 hour and 15 minutes. The route winds through a dense Jeffrey pine forest, where you can often catch the distinct scent of vanilla from the trees. Keep an eye out for vibrant wildflowers lining the road and the chance to spot deer. While the forest canopy provides a serene atmosphere, on clear days you might glimpse the distant Sherwins and White Mountains.

Planning your visit to the Mammoth Scenic Loop is straightforward, especially during the summer months when it is a popular choice for road bikers. You will find wide shoulders along the route, which contribute to a safer cycling experience compared to busier roads like Highway 395. Parking is generally available, making access to the trailhead convenient for your ride. Consider starting your journey earlier in the day to enjoy cooler temperatures and potentially fewer people on the path.

This route is notable for its unique geological features, including the Inyo Craters. These fascinating volcanic formations were created by ancient steam blast eruptions and are a significant natural attraction you can explore along the way. The trail offers a distinct experience of the region's natural environment, showcasing its diverse ecosystem and providing a memorable ride through a landscape shaped by both forest and volcanic activity.

The Horseshoe Lake – Twin Lakes loop offers a rewarding road cycling experience through the stunning Mammoth Lakes region. You'll climb steadily along the paved Lakes Basin Path, winding through old forests and past feeder streams, with constant, sweeping views of the Owens Valley and the dramatic Mammoth Crest. The route takes you past Lake Mary and on to Horseshoe Lake, providing a diverse journey through alpine landscapes.

This difficult 39.1-mile (62.8 km) ride involves a significant 3510 feet (1070 metres) of elevation gain, typically completed in about 3 hours and 22 minutes. The main path is smooth and often separates you from vehicle traffic, making for a safer ride. While the overall route is challenging, the Horseshoe Lake loop itself is a gentler, family-friendly option with mixed dirt and paved sections.

Horseshoe Lake is unique as the only road-accessible lake in the Mammoth Lakes basin where swimming is permitted, making it a great spot for a mid-ride break. The area is framed by sharp alpine peaks and pine trees, particularly around Lake George if you extend your ride. This route is perfect for experienced cyclists looking for a substantial workout combined with incredible natural beauty.
