Glacier point is one of the best view points in the park. You can see most of the Yosemite Valley, as well as the back country, Half Dome, Clouds Rest and many wonderful named peaks. Four major water falls are seen from Glacier Point which run all year round. The Yosemite Falls, Vernal Falls, Nevada Falls, and Illilouette falls can be viewed as you walk around the point.
Next time you are here take some time to do a night hike. Find an open place and marvel at the Milky Way, stars, planets, and meteors as they perform their nightly parade of enchantment.
Enjoy the peace and solitude that comes with the evening in Yosemite. While most people are in camp, or back in their rooms the valley offers uncrowded trails, and meadows for anyone who wants to experience the magic, and wonder of the night.
Stars, animals, and the sounds of nature replace the mechanical, and civilized sounds of the day. The night gives us the gift of less to see, and more to hear, smell and wonder at.
I enjoy the night, and love to hike on a full moon. As a photographer I am pretty much just a hack so here is the best technical advice I can give. Just about all of my night shots are taken with lots of moon light. I use a tripod which is a must. A work around would be to place your camera, (so it won't fall) down on a solid surface and take a photo with the auto timer count down feature. I do not have a motor drive so my exposures are generally less then 90 seconds.
