Most hikers are aware of the potential danger that snakes pose and take steps to avoid them. Common sense dictates that you stay on trails, don't put your hands or feet in places you can't see, and be especially careful when climbing rocks or logs. Some people carry a hiking stick to help prod ahead of them as they walk. Wearing long pants also helps protect against snakebites.
In addition to avoiding snakes, it's also important to know what to do if you are bitten by one. The best course of action is to remain calm and call for medical help immediately. If you are unable to get help, try to keep the affected limb below heart level and wait for the swelling to go down before walking out. It is also important to remove any tight clothing or jewelry from the area in case of swelling.
