For someone from Florida, Arches blew me away. Early March was a great time to go. The weather was perfect. There are a ton of arches of varying difficulties to see. Definitely plans to spend hours on hours there. Don't rush anything and also don't forget to put the camera down and just enjoy it for it's natural beauty.
Landscape arch is great! Definitely worth the hike. It's a moderate hike that has a couple arches along the way. It's only 0.8 miles to Landscape Arch which with the other two arch stops, took about an hour to get to. Absolutely stunning.
Devil's Garden is amazing ! Definitely recommend taking the hike to see that area.
