Big Bend is no more dangerous than any other desert. However, being in deserts and hiking in them is a lot different than hiking in the forest. You must be prepared and hike with caution. Be aware of poisonous snakes and spiders, and other animals like mountain lions and coyotes. You should never ever hike when it is above 95 degrees during the summer. With little shade and hot conditions, it can be very easy to get heat exhaustion. Always wear closed-toed shoes when you are hiking in the desert and bring lots and lots of water. More water than you may think you need!
