🚗 Transportation Guide
1. Departure City: About 3.5 hours drive from Albuquerque
2. Road Conditions: The last 10 miles are gravel and dirt roads, bumpy and full of potholes; a four-wheel drive or high-clearance off-road vehicle is required; regular cars are very likely to scrape the bottom
3. Travel Tips: Gas stations are scarce along the way; fill up the tank before departure; no public transportation available, self-driving only
4. Best Photography Times: 2 hours after sunrise and 1.5 hours before sunset for the most saturated rock colors; at night, you can shoot the desert Milky Way starry sky
🗺️ Three Core Routes
1. Badlands Overlook | 360° Danxia Panorama
The highest point in the area, surrounded by colorful rock pillars in a ring. In the early morning, mist covers the iconic mushroom rocks, creating a full atmospheric vibe.
Photography Tips: Use a wide-angle lens for panoramic canyon shots and a telephoto lens to compress rock layers; wear bright red, orange, or yellow clothing to contrast with the earth-yellow and orange-red rock walls for striking photos.
2. Fossil Valley Trail | Jurassic Archaeological Site
The trail surface is scattered with numerous dinosaur bone fossils visible up close, but strict rules apply:
· Maintain a 1.5-meter safe distance from fossils; no stepping on or climbing the rock layers
· You may bring a small brush to clean off loose dirt for a simple archaeological experience; it is illegal to remove any fossils
· The ground clay is soft; stay on existing trails and avoid stepping on soil slopes
3. Alien Canyon | Sci-Fi Filming Location
The most famous spot in the entire park, with fluorescent orange, mint green, and creamy white multi-layered rocks interwoven, creating a surreal color clash like an alien surface.
⚠️ Safety Reminder: The rock walls are loose and prone to collapse; strictly follow marked routes and do not venture deep into the canyon.
🌌 Night Tour Exclusive: Desert Milky Way Starry Night
Far from city light pollution, the entire wilderness reveals the full Milky Way to the naked eye at night. The rock pillars framed against the starry sky create a powerful visual impact.
Photography Gear: Tripod, large aperture camera, headlamp; use long exposure of 10–15 seconds, ISO 1600–3200 to easily capture stunning star trails.
Tips: The desert has extreme temperature differences between day and night; bring a windproof thick jacket for nighttime.
🎒 Essential Packing List
· Clothing: High-top anti-slip hiking boots, windproof face mask, wide-brim sun hat
· Water: Large capacity water bags with at least 3 liters per person; the desert has no shade and intense sun exposure, with a high risk of dehydration
· Equipment: Satellite GPS/offline maps, camera + tripod, sunscreen with SPF 50+
· Others: Basic first aid kit, some dry snacks, trash bags (all trash must be carried out)
⚠️ Strict Safety Rules & Pitfall Warnings
1. Avoid during rainy season: Heavy rains frequently occur from July to September, causing flash floods in desert canyons; visiting during this period is not recommended
2. Drone Restrictions: Drones are prohibited throughout the protected area; violations will be penalized
3. Wildlife Encounters: If you encounter rattlesnakes or venomous lizards, stay still and slowly back away without disturbing them
4. Geomorphology Protection: Do not climb fragile rock pillars, carve graffiti, or move rocks; these billion-year weathered landforms are easily damaged
5. Camping Tips: Only primitive camping is allowed; check forest fire bans in advance; open flames are strictly prohibited
