Rediscovered by Galen Clark and Milton Mann in 1857, the Mariposa Grove now is the largest natural sanctuary for the Giant Sequoia trees in Yosemite National Park. With several hundreds of mature examples of these natural wonders, the oldest tree in the Grove, Grizzly Giant, is about 1900-2400 years old and a staggering 210 feet tall.
If hiking is too mainstream for you, hitch a horseback ride with the Yosemite Cowboys in Yosemite Trails Saddle & Sleigh Company. Located near the Southern Gates of Yosemite National Park, it is easily accessible from The Pines Resort. Attractions like the Chilnualna Falls are also nearby.
