Moab is at a lower elevation than most areas in the region. This means that this is also gets hotter here. The temperature was approaching 100 degrees the day I was there. The sun is also very very strong.
I'm not the most experienced hiker in the world, but i'm not the least either. While pushing my friends off the beaten path on a trail we went to we noticed some older people straggling along behind us. we'd stopped to chill for a bit on a flat outcrop, but we watched/overheard them for 10-15 minutes trying to decide where the trail went. after a while they started wandering off in a completely opposite direction because they couldn't get back up the way they came.
Long winded, but what i'm trying to say is that if you're an inexperienced, or incapable hiker, make sure you follow the trail or have someone who knows what they're doing. it's easy to take a wrong turn and change a fun thing into tragedy really quickly.
These are a couple of pictures I saw of what can happen out there in the country. These are more than likely rentals, so who cares?
It can be really hot here in the summers, so make sure you drink alot of water while visiting the National Park.
Be prepared for hiking in the park. One should have plenty or fluids with them (not in the car- like I did) and sunscreen. I was not properly perpared!!
You can be fined for litering in the National Parks. Also, you are not to take any rocks or remove items form the parks too.
Cloud to ground lighting strikes are common during the summer months. Be careful and keep an eye on the sky!
