Yosemite is one of my favorite places to visit. Check out
www.nps.gov/yose/home.htm and
www.nps.gov/yose/wilderness/ and
www.yosemite.org for more info. If you want an easy hike stroll up to the base of Yosemite Falls. A little longer, but still easy is the Happy Isles Trailhead that gets to the base of Vernal falls about 1 mile from Curry Village. If you are feeling adventurous, take the Four Mile Trail to the top of Glacier Point from the valley floor. It is a tough climb, but the vew is incredible almost all the way up. The waterfalls will be spectacular with all of the recent snow and rain.
