The Petrified Forest Loop trail is located in Theodore Roosevelt National Park, North Dakota. Access points are typically from the North Unit of the park. Parking is available at designated trailheads within the park.
This extensive trail offers a diverse landscape, including prairie, badlands, and sections dense with petrified wood. You'll experience sweeping views of the Little Missouri River and its valley, as well as eroded badland hills. Much of the loop, particularly the middle section, traverses open prairie grasslands. The North Petrified Forest Trail section involves significant elevation changes, including a 300-foot descent followed by an immediate 300-foot ascent. Be aware that the trail can become very slick after rain.
The trail is renowned for its petrified wood, as Theodore Roosevelt National Park boasts the third-highest concentration in the United States. You'll also find opportunities for wildlife viewing, including bison. Specific highlights along the route include the Petrified Forest Loop Trailhead, the Petrified Forest Trail South Section, and the Petrified Forest Trail North Section.
Yes, the route also passes through sections of the Maah Daah Hey Trail, the Painted Canyon Loop Trail, Mike Auney Trail, and the Lone Tree Spring Loop Trail.
The best time to visit for hiking is generally during the spring or fall when temperatures are milder. Summers can be very hot with little to no shade, and winters can be harsh. Always check the weather forecast before heading out.
Pets are generally permitted on trails in Theodore Roosevelt National Park, but they must be kept on a leash no longer than 6 feet at all times. Always check the latest park regulations on the official NPS website before your visit.
Yes, Theodore Roosevelt National Park charges an entrance fee. This fee typically covers entry for 7 consecutive days. Specific permits are not usually required for day hiking on established trails like the Petrified Forest Loop, but it's always best to check the official National Park Service website for the most current information on fees and regulations.
Given the trail's length and exposure, it's crucial to bring ample water, especially since there is little to no shade. Sun protection (hat, sunscreen, sunglasses) is essential. Sturdy hiking boots are recommended, and trekking poles can be helpful for the steeper sections and if the trail is slick. Pack snacks or a lunch, and be prepared for changing weather conditions.
The full Petrified Forest Loop is a long hike, typically 10.4 to 10.5 miles, and is considered strenuous due to its length and some steep portions. While a substantial part is flat, the overall difficulty might be challenging for beginners or young children. Shorter, easier options might be available elsewhere in the park if you're looking for a more family-friendly experience.
The length of the trail and lack of shade are significant challenges. Long stretches through grasslands can feel monotonous to some hikers. The trail can become very slick after rain, making footing difficult. Always carry enough water and be prepared for potential wildlife encounters, including bison.
While the park itself does not have extensive services, nearby towns like Medora, North Dakota, offer various options for accommodation, restaurants, and other amenities. It's advisable to plan your meals and lodging in advance, especially during peak season.
