Here's the trip map from my May desert road trip. We did the trip in about 4-5 days, though if we had more time then there would have been many more incredible stops along the way. Who knew all of those geological wonders were so close to each other? It's definitely a trip I'll take again because it's just that scenic. By the way, we used hoteltonight.com to allow the journey to be spontaneous and it got us into some places we would have never expected. Highly recommended.
