Welcome to California’s Volcano Alley, a hissing, spitting wonderland that is home to all four types of volcanoes – shield, composite, cinder cone and plug dome. Serene Manzanita Lake makes the perfect base with a campground, cabins, a museum and a picture-postcard view of the 10,457-foot (3,187m) Lassen Peak. You can kayak or do stand-up paddleboarding on the lake, hike through the area’s largest hydrothermal area along the gentle three-mile (4.8km) round-trip Bumpass Hell Trail, or challenge yourself on Ridge Lakes Trail that leads to a pair of alpine lakes at a basin with a lofty elevation of 8,000 feet (2,438m).
