<human>:  I’m planning a hiking trip in the Olympic National Park. What do I need to bring and what to watch out for on the trail?
<bot>: You should bring plenty of water and snacks for your hike, as dehydration and hunger can be dangerous in the wilderness. It's also important to wear proper hiking gear such as shoes with good traction to prevent slipping, and clothing that provides protection from the elements. Depending on the trail you choose, you should be sure to watch out for poison ivy, wild animals such as bears and coyotes, and changing weather conditions. It's also a good idea to wear bright colors or carry some type of signaling device, in case of an emergency. Lastly, always make sure to stick to the trail and never wander off without a guide.
