The trail is easy to follow along the rim trail even if the All Trails says different. It is difficult to find the path that takes you down the Mesa Rim, so you would need to make your own way down. The trail starts to disappear once to start hiking to the other end of the Mesa. Once you go behind it, it becomes obvious where you are going. Voila! You see the Cobra Arch! Don’t go in Monsoon season ✌
