In an effort to preserve this park, access is restricted to 50 people per day. Early morning hikers and campers have the best shot of getting in, and once registered, are welcome to stay for up to two days. The canyon area is hikeable, but not for beginners. Its 1,000 foot walls and splendid array of colors make this a gorgeous walk and climb. The largest population of Mexicana desert sheep in the United States roam freely here, and are common sites in the camp area and on the trails.
Campsites are on the rugged side.
Hiking, hunting and wildlife observation is free. Hikers are advised to bring extra water, several changes of layered clothing, and wear a hat and sun protection at all times. Many trails are groomed, but you're welcome to forge your own way into the wilderness. A 28 mile scenic drive through the park is a popular day excursion for many locals and tourists. Traffic is heavy on the drive, but can be biked and walked.
