Skiing and Backcountry Adventure in the Sierra Nevada

Skiing at Bear Valley Mountain remains excellent thanks to the dedicated snowmaking and grooming crew that keeps conditions in top shape. Whether you’re a seasoned backcountry traveler or just starting out, the surrounding terrain offers experiences that inspire and challenge all skill levels. As you take in the snow-covered peaks, you’ll see why locals are quick to grab their backpacks and snowshoes once resorts begin to close and mountain passes reopen, creating endless opportunities for hiking and spring skiing well into May.
Visitors can also enjoy snowmobile rentals on wilderness trails through Bear Valley Snowmobile. For snowshoe rentals and guided adventures, check with Bear Valley Adventure Company and Sierra Nevada Adventure Company, and be sure to visit the Sierra Avalanche Center for the latest backcountry conditions and safety updates. From November through May, a Sno-Park permit is required when parking at winter access points at the end of mountain roads.
Exploring the Cave Systems of Calaveras County

Calaveras County is home to some of California’s most fascinating cave systems, offering visitors a unique underground adventure. Moaning Cavern, located near Vallecito, is the largest single-chamber cave in California and is famous for its enormous open-air chamber. Visitors can explore its winding passageways on guided walking tours or, for the more adventurous, rappel 165 feet into the main chamber, experiencing the echoes that give the cave its eerie name.
Not far away, Mercer Cavern in Murphys showcases a stunning display of stalactites, stalagmites, and delicate mineral formations. This privately owned cave has been carefully preserved, and guided tours highlight both its natural beauty and its fascinating history, including stories of early discovery in the 19th century. Mercer Cavern offers accessible tours for families while still giving a sense of the underground mystery that makes Calaveras County caves so special.
For those looking to go deeper into history, California Cavern, also near Murphys, is renowned as the first cave in California opened to the public. Visitors can explore its extensive passageways, some of which were used during the Gold Rush era, and see remarkable rock formations that have developed over thousands of years. Together, these three cave systems—Moaning Cavern, Mercer Cavern, and California Cavern—offer a perfect mix of adventure, geology, and history, making Calaveras County a must-visit destination for cave enthusiasts and families alike.
