Lassen Volcanic National Park
Head over to northeastern California to experience Lassen Volcanic National Park. This sprawling park is home to gorgeous mountains, valleys, and even some unique thermal features such as hot springs. This is a great park to visit year-round, with ample activities in both the colder and warmer months. If youβre visiting in the winter, Manzanita Lake and the southwest areas of the park are open year-round. Sulphur Works is the one hydrothermal area thatβs open in the winter but does require skis or snowshoes to reach in the snowier times of the year. The previously Manzanita Lake area also offers some great opportunities for cross country skiing. Summer activities, meanwhile, include camping, swimming, and hiking. Wildflower season also runs from May-September and offers some amazing fields of wildflowers.
