Balanced Rock:

Last summer I went on an amazing adventure with the lovely ladies at Balanced Rock. This is a nonprofit organization based in El Portal (just outside Yosemite Valley) with a team of inspirational women that guide trips in and around Yosemite National Park. These wilderness trips are a wonderful way to introduce yourself to the backcountry in a safe and comfortable way. Most trips are led by women, for women. A typical course incorporates elements of hiking, writing, yoga, and art. Let Balanced Rock nurture you into the wilderness.
