The theme of our Arizona roadtrip is waterfall and caves in the Sonoran desert with beautiful saguaros. On the first day we drove through a monsoon with roads flooding in Phoenix and Scottsdale. Our Boulders Resort stay in Scottsdale was so relaxing and looks like an arboretum with lots of saguaros cactus and boulder rock landscaping among golf courses. Their adobe casita rooms match the rocks. On the second day, we hiked to the Papapago Park Hole in the Rock in 100 degrees heat and visited the Desert Botanical Gardens and learned about butterflies, cactuses, animals living in the Sonoran desert. We hiked to the beautiful Tonto Natural Bridge Cave northeast of Phoenix AZ where we had to rock scramble on slippery rocks and a river to get to the cave. We then offroaded 15 miles to see the majestic Grand Falls Arizona that is fed by the Colorado River. There was recent monsoon that filled this majestic chocolate falls. We visited the Wupatki National Monument, near Flagstaff that preserves pueblos once inhabited by ancestors of the Hopi and Zuni people, amid red rocks and prairies. All the watercolor and acrylogouache cactus and succulent paintings above were inspired by Arizona's gorgeous Sonoran desert landscapes. We made it to the North Rim of the Grand Canyon driving about 2,000 miles round trip. In my humble opinion, the views of the North Rim are more gorgeous than the South Rim and there are fewer crowds. There are very few guard rails so you get as close to the edge as you feel comfortable. We explored the Navajo Moenave Dinosaur Tracks in Tuba City AZ and saw many velociraptor tracks and bones. On the last day we went to the West Rim of the Grand Canyon and saw the Eagle Point rock, Skywalk and saw spectacular river views at the top of Guano Point. The skywalk tickets were pricey but it wasn't too scary to walk it as the glass is scratched up so you can't see that you're 4,000 feet above ground with rocks below you. The Skywalk is 10ft wide and extends 70 ft over the rim. It was worth traveling the long distance from the North Rim to West Rim to see the magnificent red rock views of the canyon.
