Temps were hot in Moab, so I wasn't as eager to go hiking and we only stayed a few days doing the whirlwind tour.
We checked out the Needles district of Canyonlands first. We stayed in the campground in the park, which was pretty nice, but the gnats were horrible. The rock formations were pretty though.
Island in the Sky district of Canyonlands is pretty incredible. It was hazy due to some fires in NM, I think. Still, the canyons were beautiful.
We drove over to Dead Horse Point state park one afternoon to check out the view there. Very nice park.
We went to Arches early one morning since parking can be an ordeal, especially with a larger vehicle. It was also cooler then and we enjoyed a couple short hikes.
Here's a picture of Brion at Turret Arch. To get an idea of the grand scale, notice that there's a guy in a yellow shirt below the arch. Click on the picture to get a larger view, if needed.
Here's a shot of Tunnel Arch.
And one of Landscape Arch. Note that these pictures don't do these formations justice at all, especially in the case of Landscape Arch. This is such an incredible formation to behold. It's nearly 300 ft across. The trail to this arch was closed a few years back after a big chunk of the arch fell. More info on this arch here.
