The Zhangye Danxia National Geological Park stretches across 510 km² in northwestern Gansu province, roughly thirty kilometers west of Zhangye and 20 km south of Linze. Known for its ridges streaked with red, orange, and ochre, it earned the nickname Rainbow Mountains Geopark and forms part of the serial site China Danxia, inscribed on the UNESCO World Heritage List in 2010.

Why visit Danxia Park

The site combines significant geological interest with a rare landscape across Chine. The layers of sandstone, mudstone, and red rock that compose the conglomerate accumulated between two tectonic plates over nearly 24 million years. Wind erosion and climatic shifts have carved undulating ridges, precipices, columns, and stone needles, exposing a colorful stratigraphy rarely seen at such a grand scale.

The appeal is both scientific and visual: the color bands correspond to successive sedimentary deposits, whose oxidation and mineral content explain the red, yellow, and gray hues. Visitors especially appreciate the contrast of light at dawn and dusk.

Geological formation and historical context

The Danxia conglomerate formed through accumulation of sedimentary layers between two tectonic plates over approximately 24 million years. Once uplifted, these strata were progressively exposed by wind and water weathering, creating the landforms visible today along the banks of the Liyuan River.

Historically, Zhangye held strategic importance in antiquity: it ranked among the four western prefectures of the Yellow River, a crucial stop on trade routes connecting inland Chine to Central Asia. The park itself was only developed for tourism from the 2000s onward, following scientific recognition of the site.

What to see in the park

The park is organized into two main massifs, north and south, offering two distinct experiences.

The colorful hills

This is the most photographed section of the site. Several observation platforms are set up along a trail serviced by internal shuttles. The two most renowned viewpoints are:

• the Seven Colors zone, offering a broad panorama over undulating strata;
• Colorful Sunset, positioned to capture late afternoon light.

Depending on the sun's angle, the tones shift between brick red, vivid orange, ochre yellow, and ashen gray. The appearance changes markedly from hour to hour, making at least two visits the same day worthwhile.

The ice valley (Binggou Danxia)

Located further afield, this zone extends 40 km from west to east. It stands out for more vertical formations: precipices, stone columns, needle-shaped hills. Nicknamed the Red Stone Forest Valley of the Great Northwest, it evokes architectural silhouettes in places—pagodas, stupas—carved from sandstone. It draws fewer crowds than the colorful hills and requires an additional half-day.

When to visit

The park is open year-round, though the quality of experience depends heavily on season and light.

• May to October: most favorable period, long days, mild temperatures, vivid colors after rare rains that revive the pigments in the sandstone.
• June to September: peak tourist season, significant crowds at main viewpoints.
• November to April: short days, cold wind, low-angle light but fewer visitors.

The best times of day are the first hour after sunrise and the last before sunset: oblique light accentuates relief and color saturation. Conversely, at midday, contrasts flatten.

Practical information

• Duration: allow 3 to 4 hours for the colorful hills alone, an additional half-day for the ice valley.
• Admission: moderate entrance fee, internal shuttle extra (often mandatory). Combined tickets cover access to main platforms.
• Hours: extended opening from April–May through October (early morning to early evening), shorter slots in winter. Verify current hours the day before your visit.
• On-site: little shade; bring a hat, water, and windbreaker. Trails between viewpoints are short but exposed.

How to get there

The park lies approximately 30 km west of Zhangye.

• By air: direct flights from Lanzhou, Xi'an, Urumqi, and Dunhuang to Ganzhou Airport, 65 km from the park. Taxi or private car to the entrance.
• By bus from Zhangye: direct shuttles to the park entrance from the city's bus station.
• Regional bus: Zhangye–Sunan line with intermediate stop at Nantaicun, minutes on foot from the entrance.
• By train: Zhangye is served by the Lanzhou–Xinjiang high-speed line, then taxi or bus to the park.

Nearby

The park sits within a broader circuit around the Hexi Corridor, rich in Buddhist sites and desert landscapes. To extend your visit:

• Zhangye, the logical starting point, merits a day for its reclining Giant Buddha and historic center.
• The Beishan temple, a classic spiritual stop in the region.
• Further northwest, Aiding Lake showcases another facet of northwestern Chine's arid landscapes.
