Mention Inner Mongolia, and many people imagine endless grasslands filled with horses and yurts. While those landscapes certainly exist, the region also hides one of China’s most surprising natural treasures—a vast wilderness of volcanoes, alpine lakes, forests, rivers, and hot springs.
Welcome to Arxan National Forest Park (阿尔山国家森林公园), a destination unlike anywhere else in China.
Located near the borders of Mongolia and Russia, Arxan combines dramatic volcanic landscapes with pristine forests and some of the cleanest air in the country. Despite its extraordinary beauty, it remains largely unknown outside China, making it a dream destination for travelers seeking unspoiled nature.
Where Is Arxan?
Arxan is located in the northeastern part of Inner Mongolia Autonomous Region, close to both Mongolia and Russia.
Although the city of Arxan has fewer than 100,000 residents, it serves as the gateway to one of China’s largest and most beautiful forest parks.
The journey itself is part of the adventure. Visitors can arrive by train, domestic flight, or road from cities such as Hohhot, Harbin, or Ulaanhot.
As the landscape changes from grassland to dense forest, it becomes clear that this is not the Inner Mongolia many people expect.
A Landscape Created by Volcanoes
Millions of years ago, volcanic eruptions transformed this region into a landscape unlike any other in northern China.
Today, visitors can explore:
- Ancient volcanic craters
- Lava fields
- Basalt formations
- Mineral springs
- Crystal-clear rivers
- Forest-covered mountains
Unlike active volcanoes, Arxan’s volcanoes have been dormant for thousands of years, allowing forests and wildlife to reclaim the land.
The result is a rare combination of geological history and thriving ecosystems.
Tianchi Lake – The Mysterious Crater Lake
One of Arxan’s most famous attractions is Tianchi, or Heaven Lake.
Unlike many crater lakes around the world, Tianchi has no visible rivers flowing into or out of it.
The lake sits quietly inside an ancient volcanic crater, surrounded by dense forests.
Its water level remains remarkably stable throughout the year, giving rise to numerous local legends.
Scientists believe underground springs help maintain the lake, while visitors simply admire its peaceful beauty.
On calm days, the surrounding forests are perfectly reflected in the deep blue water.
Endless Forests and Fresh Air
More than 80% of the park is covered by forest.
Larch, birch, pine, and spruce trees stretch across the mountains, creating one of northern China’s richest forest ecosystems.
During summer, temperatures remain pleasantly cool, offering relief from the heat found elsewhere in China.
In autumn, the forests transform into brilliant shades of gold, orange, and red, attracting photographers from across the country.
Many visitors describe Arxan as feeling more like northern Europe than northern China.
A Land of Rivers and Waterfalls
Water is everywhere in Arxan.
Snowmelt and underground springs feed countless rivers and streams throughout the park.
One of the highlights is the Unfrozen River, which continues flowing even during the coldest winters.
Nearby waterfalls, wetlands, and wooden boardwalks allow visitors to experience the park’s diverse landscapes up close.
Because of the exceptionally clean environment, the water remains remarkably clear.
China’s Famous Hot Springs
The name “Arxan” comes from the Mongolian language and is often translated as “hot spring.”
The region contains dozens of mineral springs with different temperatures and mineral compositions.
Some have been used for centuries by local communities for bathing and relaxation.
Today, visitors can enjoy modern hot spring resorts after a day of hiking and sightseeing.
The combination of cool mountain air and naturally heated mineral water makes Arxan a popular wellness destination.
Wildlife in the Park
The forests of Arxan provide habitat for a wide variety of wildlife.
Although many animals remain elusive, the park is home to:
- Red deer
- Moose
- Foxes
- Wolves
- Brown bears
- Squirrels
- More than 200 bird species
Lucky visitors may spot deer grazing near forest roads during the early morning or evening.
Because much of the park is protected, biodiversity has remained remarkably well preserved.
