While in Goblin Valley last weekend, we decided to do an 8 mile hike that goes up one slot canyon over to the other slot canyon and down the other slot canyon. It was a cool hike. However... it was so hot that I thought I was going to die. It would have been cooler if it weren't almost 100 degrees outside. It is a very neat hike though... can't be claustrophobic or too fat or else you wouldn't fit. ha ha It got REALLY narrow! It was nuts! Hiking through slot canyons is cool though. I totally recommend it.
