Month-long volunteering in Yosemite.  This is the way to realize your dream vacation: go to work there!  We attended the 80th Anniversary of the Yosemite Association.

Yosemite National Park

This is perhaps the best hiking in the world.  It is close to major population centers and the backcountry is accessible, though rugged.  Half dome is recognized around the world.  We climbed half dome on this trip.


Numerous visits
