Yosemite National Park

But no temple made with hands can compare with Yosemite. Every rock in its walls seems to glow with life. Some lean back in majestic repose; others, absolutely sheer or nearly so for thousands of feet, advance beyond their companions in thoughtful attitudes, giving welcome to storms and calms alike, seemingly aware, yet heedless, of everything going on about them.
John Muir

Yosemite is one of the most visited national park in the United States. The valley was carved by glaciers during the last ice age and has spectacular waterfalls. I have been there several times, and each time I see something new.

The amount of water in the streams and waterfalls is highly dependent on what time of year you go. In May and June, there is plenty of water in them from the melting snow. By August They are but a trickle and sometimes they completely dry up!

Gallery of Half Dome
Half Dome is such a beautiful and imposing sight that you can't sum it up with a single picture, so I have a whole page of them.

Gallery of Sentinel Dome
There is a popular hike along the road to Glacier Point that takes you to the top of Sentinel Dome. It isn't very steep (except at the very end) and you get a good view.

Gallery of Yosemite Falls
One of the defining waterfalls of Yosemite is Yosemite Falls. Actually, it is two, the Upper Fall and the Lower Fall.

Gallery of Bridalveil Fall
The first major waterfall you see when you enter the park, probably the most recognized one too.

Mariposa Grove Gallery
The Mariposa grove is one of three groves of Giant Sequoias in Yosmite National Park.It is hard to capture the scale of these trees in a picture. They are so huge that you have to stand pretty far back to get the whole tree in the photo, but suffice it to say that they are big, very big.

Gallery of Yosemite in the Winter
Yosemite is open all year round. Some parts of it close because they get too much snow to plow, but the main valley is generally open. It is much less crowded in the winter and it is very pretty.

More Yosemite Photos
Beyond The really popular places to go, there are hundreds of other lesser visited sights that are also beautiful. Here are some of them.
