This review is LONG overdue. We took this bus tour from downtown San Francisco to Yosemite Natl. Park just before the tragic fires of late in the area. We were lucky that (like the description on the website says) conditions WERE right, and we were able to tour the area of the Giant Sequoias, Swinging Bridge on the Meadow Loop Trail, and get so close to Yosemite Falls that we could almost touch it.
The website is pretty easy to navigate. Determine where you want to be picked up, purchase your ticket(s) and you're done. You ride for an hour and half or so before your stop, at which time you'll be able to stock on snacks, and other necessities. This is a LARGE grocery chain (can't remember the name) and if you can't find it here ... including an umbrella, you must not be looking hard enough. Same trip in reverse on the way home.
As far as the park goes, well, let the pictures speak for themselves. My wife and I travel LOTS. We have been all over the United States, and this was some of the top 5 scenery we've EVER witnessed. Enjoy!
Good job Extranomical Tours!
