In the last days of November and in December I traveled again in USA for almost three weeks to visit some of the National Parks I already knew and four State Parks unknown for me. The visit, presented here, is organized as numbered galleries in a chronological way of each one of the places I visited. I decided to make those galleries as a trip and not add, for instance, the photos made in Bryce Canyon in the Bryce Canyon Gallery that already exists. That way, everybody that visit the USA 2010 galleries can understand how the trip was organized and see those wonderful places in the same sequence as I've saw. It was not supposed to go to Grand Canyon but one of us never visited before. We decided to spend an afternoon in the South Rim on our way to Flagstaff. Everybody loves Grand Canyon, I didn't fall in love with the place because is so huge that you need time to enjoy it. Just stop in the view points only gives you a superficial approach of Grand Canyon. I think itīs necessary at least 5 to 7 days to really get a feeling of this special area. Don't forget that the Sky-walk is not inside the National Park, is located much near Las Vegas, from the South Rim is a five hours drive! Thank you very much for the time you spent traveling with us.
