Predators
With any animal encounter, keep in mind that you are a visitor in these wild places. Treat all animals with caution and respect. Any wild animal can become dangerous if provoked. Stay alert and avoid situations where you might surprise an unsuspecting animal.
Large predators can be encountered at any place on the Idaho Centennial Trail. Wolves, bears, and cougars live and hunt along the entire length of the trail. Anyone spending an extending period on trail is likely to run into at least one of these powerful animals. It is important to remember that an animal attack is a possibility not a probability. Human encounters with wild animals are common and as long as you remain calm and treat these animals with respect, negative experiences are not likely.
Your safety is your responsibility. Every animal encounter is unique, so you must rely on your own knowledge and instincts. You do not want to freeze up or flee in these situations. Being prepared will allow you to remain calm and be proactive in avoiding conflicts.
-Bears
There are very few grizzlies in Idaho but they are sometimes spotted in North Idaho. The majority of bear encounters will be with black bears. The best way to avoid negative bear encounters is to hike in groups and make noise. If given the chance, a bear will leave the area if it knows you are coming. Especially in thick brush, where visibility is limited and bears tend to feed in dense berry patches, singing out loud or giving frequent shouts is a good way to alert animals that you are coming.
