It is easy to lose yourself in the great big wilderness areas of California. These massive swaths of forest and backcountry are larger than some of the country’s smaller states, with infinite opportunity to explore and discover the beauty of the Golden State’s most stunning areas. If you bring your Yreka camper rental south on Interstate 5, you can reach Castle Crags State Park, named for its unique, castle-like rock formations with volcanic origins. These towering crags reach heights of over 6,000 feet and can be seen from the highway. The state park has been home to a few battles and is the only known place where the Castle Crags ivesia and the Castle Crags bellflower are known to grow. Ahjumawi Lava Springs State Park is another fantastic place to bring your Yreka RV rental in search of amazing natural sites. Much of the park is blanketed with jagged, black basalt formations caused by ancient pyroclastic flows seeping from deep below the Earth’s crust. You can also go hiking, kayaking, canoeing, swimming, or fishing for trout and bass in the freshwater springs situated throughout the park. Lava Beds National Monument to the east and Cascade-Siskiyou National Monument to the north just over the border are two breathtaking landmarks worth visiting when you rent an RV in Yreka. Both of these stunning monuments have volcanic remnants, labyrinthian caves, underground ecosystems, archaeological sites, and large geological features that you can hike for splendid views. You can also head north to Oregon and visit Crater Lake National Park, perhaps the most beautiful park in the entire Pacific Northwest. Crater Lake is formed in a now-extinct volcano. Mount Mazama, the ancient mountain that holds the alpine lake, exploded millions of years ago, which led to the development of one of the deepest and clearest lakes in the world. This World Heritage site and natural landmark is a legendary place to hike around, swim, or boat on the frigid lake.
