Imagine that you're only connected by twoclipsand a cable as you step onto a wire to explore thecanopyof a redwood forest. The remarkable trees take your mind off the fact that you're 150 feet above the ground!

You can experience this thrill at Mount Hermon Adventures in the Santa Cruz Mountains of California. The ride was inspired by an eight-year-old girl who donated her savings to build a zip line through the area's redwoods. Her idea led to the creation of two adventures: a zip line tour and a suspendedobstacle coursethat lets you push your limits in a safe environment. The tours, which are open to the public, are available year-round for anyone over the age of 10. Since 2008, more than 100,000 people have participated.

“Sequoia Sky Adventure and Redwood Canopy Tours provide a way for people who are staying at the camp to experience the redwoods and enjoy an outdoor activity,” says Cameron Leonard, an operationsupervisorat Mount Hermon. Leonard describes the sky adventure as “a challenge by choice, pushing personal boundaries since there are challenging obstacles you have to cross over while you're at varying heights.” During the tour, two trained staff members teach you about the trees. There are three types of redwoods around the world. But only the coast redwood, which is Earth's tallest tree,can be found in the Santa Cruz Mountains.

Because of logging in the mid-1800s, Mount Hermon is primarily a “second-growth forest”.There are, however, a few trees that are believed to be between 600 and 1,000 years old.The most unique thing about redwoods is that they clone themselves. When the top of a tree breaks off during a storm,a bud from inside the trunk will grow out of the side to form a “new tree”. There is an entire ecosystem of birds, lizards,salamanders, and other animals in the forest canopy.

“It doesn't matter what time of day you go there,” Williams says. “It's pretty amazing from the morning to the afternoon, and the way the sun shines through the trees is just beautiful.”
