A classic Hidden Villa trip with a climate science twist. Join us for the backpacking trip you will never forget in Yosemite National Park. After spending the first few days at Hidden Villa, the group will spend 15 days exploring San Francisco’s water source; starting at Hetch Hetchy Reservoir, hiking into Tuolumne Meadows, and ending in Yosemite Valley! Along the way the group will transform into citizen scientists to recreate historic photographs, volunteer with the National Park Service and return to the farm with memories that last a lifetime. The program is a total of 18 days, averaging 7 miles per day over varied terrain. Participants must be in good health, complete a doctor signed health form and have a strong interest in backpacking. Completion of the Bay to Sea backpacking trip is recommended but not required.
