Hiking in the desert can be a challenge, and you'll want to be prepared no matter what time of year you visit. Make sure to wear a hat, sunscreen, and comfortable shoes. Be sure to pack a park map, available at the Visitors' Center. Bring along a day pack filled with snacks and plenty of drinking water. A cell phone, compass, and multi-tool can be helpful. Leashed pets are allowed in designated picnic areas, parking lots and roadways, but if you plan to hike any trails, leave your pets at home.
