"They should have sent a poet." - Dr. Ellie Arroway
The phrase 'Pictures don't do it justice' had to have been said first by someone looking over Glacier Point in Yosemite National park. We spent all of Day 30 hiking in Yosemite, getting up early and going hard until arriving back at our home base in Mariposa for an 8:00 pizza dinner and then bed. We concentrated on the Valley area - El Capitan, Bridalveil Fall (which was really just a trickle of water - 4 years of no rain will do that I guess), Tunnel View, Valley View, exploring the Village area, hiking under the Royal Arches and various other trails, and ending the day with a drive up to Glacier Point (we started the 4-mile/3,200' climb, made it about a 1/3rd of the way and thought the car was a better idea...).
If you haven't been to Yosemite, and specifically if you haven't been up to Glacier Point, I suggest you try to do it before you die. Speaking for myself, it was my favorite Big Trip stop so far and the most beautiful and majestic thing I have ever seen.
