Calaveras Big Trees State Historic Park has been a major tourist attraction since the 1800s when (prior to it being declared a state park in 1931) it suffered extensive damage at the hands of visitors. The resulting devastation is now part of the park's current draw: A lesson on the importance of nature preservation unlike any other. This includes the 'Discovery Tree' which was cut down in 1853, leaving a giant stump large enough to be used as a bowling alley, and the 'Pioneer Cabin Tree' which had an actual tunnel cut through it in the 1880s. The park has two groves of giant sequoia trees that encompass 6,498 acres and with four furnished post-war rental cabins, two main campgrounds, six picnic areas and hundreds of miles of established trails, it offers something for everyone.Parking and public transportation at Calaveras Big Trees State Historic ParkAlthough no public transportation options are available since the park is located so far out of town (four miles northeast of Arnold, CA and a 35 minute drive from Angels Camp), adequate parking is offered. The parking lots are paved, clearly marked and well-maintained. As an added bonus, the drive is very scenic and highly recommended.Best and worst time go to Calaveras Big Trees State Historic ParkThe area is especially beautiful during the winter when the park offers exceptional opportunities for playing in the snow and even cross-country skiing but the road conditions can be icy (chains are often required) and some areas of the park and campgrounds are prone to closures. To best experience the sights and enjoy the park trails with the least chance of weather interruptions, the summer months are ideal. June through August, the park also offers many extra activities like evening ranger talks, junior ranger programs, bird watching, mountain biking and educational programs.Admission to Calaveras Big Trees State Historic ParkThere is a fee to visit the park, which must be paid at a kiosk prior to entering the parking areas. It runs about $10 per car but discounts are offered if there is a senior in the vehicle. Various types of annual passes are also offered, which can be a great deal for frequent visitors.Must see/do at Calaveras Big Trees State Historic ParkIf you only have time for one trail, make it the North Grove Trail. This easy walk is ideal for young children and the elderly because of the level path and relatively short length, yet takes visitors to several historically significant landmarks. It's only about a mile and a half long but allow 1-2 hours for the hike because there are numerous photo opportunities and markers along the trail that describe the significance and history of various spots. If you forget your camera, just stop by the gift shop afterward. Postcards featuring the most magnificent of the trees are available for purchase and make great (and affordable) souvenirs.Other places to visit near Calaveras Big Trees State Historic ParkIf you enjoy the sites of the park but camping isn't your style, check out The Murphys Historic Hotel, a short drive away (in the town of Murphys, CA) where you can stay in a room once occupied by Mark Twain or sleep in the same bed where President Ulysses S. Grant once rested his head. It was also featured in an episode of "Hotel Hell" so the hotel's restaurant now offers menu items from renowned chef Gordon Ramsey. Otherwise, for a more low-key (and affordable) dining option that still holds some television fame, check out "Hillbillies". Located up the road and around the corner from the hotel, Hillbillies was featured on an episode of "Restaurant: Impossible" and boasts a menu and décor makeover provided by Chef Robert Irvine and his team.Insider tip for visitors to Calaveras Big Trees State Historic ParkOn your way to the park, follow the signs along Highway 4 (four miles east of Murphys) to "The Red Apple". There you can pick up a warm apple pie and some freshly pressed sweet cider to add the taste of authentic mountain-grown apples to your Big Trees picnic. At the very least, do what the locals do and buy a few of their famous apple cider doughnuts to snack on during the drive (if they even make it back to your vehicle).Author's bio: Ann Milligan is a wife, mom, author and artist who resides in California's beautiful Motherlode region.
