Summit Lake

The Summit, Horshoe, Snag, Cinder Cone, Rainbow, Twin, and Echo Lakes Loop offers a diverse and challenging backcountry experience, weaving through Lassen Volcanic National Park's dramatic landscapes. You'll journey from serene fir forests around lakes like Echo Lake to the striking volcanic terrain of the Cinder Cone and the Fantastic Lava Beds, witnessing the park's geological wonders up close. This difficult route, covering 25.9 miles (41.6 km) with 2959 feet (902 metres) of elevation gain, is a true test of endurance, typically requiring nearly 12 hours of hiking.

Planning for this extensive loop means preparing for varied conditions and significant effort. While specific parking and permit details aren't always highlighted, it's wise to check park advisories for any seasonal closures or wildfire impacts, as the 2021 Dixie Fire left its mark on some areas. Mosquitoes can be prevalent, especially in late spring and early summer when wildflowers are at their peak, so pack appropriate protection.

This route stands out for its unique blend of pristine alpine lakes and raw volcanic geology, offering a sense of solitude in its more remote sections. It's an excellent choice for experienced hikers seeking a comprehensive tour of Lassen's natural features, including the colorful Painted Dunes and numerous picturesque lake shores. The visible signs of wildfire recovery also add a unique, thought-provoking dimension to the journey.

The North Lakes Loop offers a deep dive into Lassen Volcanic National Park's serene alpine backcountry, connecting a remarkable concentration of over a dozen unique lakes. You'll wind through dense fir forests, past areas recovering from wildfires, and alongside highlights like Silver Lake, known for its potential for stunning reflections. The terrain is a mix of rocky paths and relatively flat sections, with continuous gains and losses in elevation, providing a diverse and engaging experience for those who appreciate high-elevation lake scenery.

This is a difficult 12.2-mile (19.7 km) hiking route with 1373 feet (419 metres) of elevation gain, typically taking around 5 hours and 34 minutes to complete. An early start is crucial if you plan to tackle it in a single day. If you're considering an overnight trip, remember that backcountry permits are required. Be prepared for mosquitoes, especially earlier in the season, and pack plenty of water for this extended journey.

What makes this trail particularly notable is its focus on the park's extensive lake system, offering a distinct experience compared to Lassen's more volcanic attractions. A portion of the loop even follows the Pacific Crest Trail, adding to its appeal. You'll find opportunities for swimming and fishing in the peaceful backcountry, and in open forest areas, you might catch glimpses of Lassen Peak and Crescent Crater.

The South Lakes Loop (Echo, Upper/Lower Twin, Swan, Summit) offers a diverse hiking experience through the stunning alpine landscape of the Eastern Sierra. You'll traverse varied terrain, from the clear waters of Lower Twin Lake to the more secluded Swan Lake, and pass unique features like the Grassy Swale boardwalk. The trail provides a constant change of scenery, culminating in the high-altitude beauty around Summit Lake, making it a rewarding journey for those who love mountain lakes and forests.

This is a difficult 12.8-mile (20.6 km) hike with 1400 feet (427 metres) of elevation gain, typically taking around 5 hours and 53 minutes to complete. Given the high altitude of the region, often starting above 8,000 feet, you should be prepared for thinner air and increased exertion. Always carry ample water and be ready for sudden weather changes, especially during the summer months. Check local conditions before you go.

While the specific combination of these lakes into one named loop isn't widely recognized, the area is known for its extensive network of trails connecting numerous alpine lakes. The Mammoth Lakes Basin, where many of these features are found, is celebrated for its dramatic Sierra Nevada backdrops and opportunities for fishing and boating. This loop offers a chance to explore some of the region's less-traveled paths, providing a sense of discovery away from the more crowded spots.
