Bogd Khan Uul: The World's Oldest National Park (2026 Guide)

Bogd Khan Uul National Park, just south of Ulaanbaatar, is widely cited as the world's oldest protected area, with its sacred status dating back to the 12th or 13th century and formal protection granted in 1778, more than a century before Yellowstone. The park centers on Bogd Khan Mountain, reaching around 2,256 meters, and combines forested hiking trails, monastery ruins, Bronze Age petroglyphs, and wildlife including musk deer and red deer.

Bogd Khan Mountain's protected status has a longer history than most visitors realize.

In the 12th or 13th century, Tooril Khan, a Mongol tribal leader and ally of a young Genghis Khan, banned logging and hunting on the mountain, treating it as holy.
In 1778, Mongolian officials petitioned the Qing Dynasty's Qianlong Emperor to formally protect the site, and the request was granted, giving the mountain official protected status.
By the late 1700s, the area held more than 20 temples and hundreds of monks, centered around what became Manzushir Monastery.
Many of the park's temples, including most of Manzushir Monastery, were destroyed during religious purges in the 1930s.
The park received official government protection again in 1957, was designated a Strictly Protected Area under Mongolian law in 1995, and became a UNESCO Biosphere Reserve in 1996.

Because of this long, layered history, Bogd Khan Uul is widely described as the world's oldest protected natural area, predating Yellowstone National Park (established 1872) by close to a century using the 1778 date, or by many centuries using the 12th-century date. It's worth noting that a small number of other sites, such as the Tobago Main Ridge Forest Reserve (protected in 1776), also claim to be among the world's oldest protected areas, so "oldest" claims in this space are sometimes debated.

Bogd Khan Mountain, the park's centerpiece, reaches an elevation of around 2,256 meters (7,402 feet) at its highest point, Tsetsee Gun. The park covers roughly 41,000 hectares of core protected area, bordered by the Tuul River along its northern edge.

The mountain's two sides look strikingly different: the northern slopes are covered in dense coniferous forest, while the southern side is largely bare rock. This contrast, along with alpine meadows and forest-steppe terrain, makes the park a distinct ecosystem from the open grassland most visitors associate with Mongolia.

Because hunting and logging have been restricted here for centuries, Bogd Khan Uul supports wildlife that's harder to find elsewhere near a major city:

Musk deer, notable for their tusk-like teeth
Red deer
Eurasian lynx
Wild boar and marmots
A wide range of bird species, including eagles and vultures

Manzushir Monastery ruins – once a major religious center with dozens of temples, now partly preserved as a museum among the remaining ruins
Bronze Age petroglyphs – ancient rock carvings scattered through the park, depicting hunting scenes and nomadic life
Zaisan Hill and Memorial – the Soviet-era memorial and viewpoint over Ulaanbaatar sits at the edge of the protected area
The Bogd Khaan Winter Palace – the former residence of Mongolia's last Bogd Khan (spiritual and political leader), now a museum, located at the foot of the mountain near the city

Getting there: Parts of the park's boundary, including Zaisan Hill, sit right at the edge of central Ulaanbaatar, making them accessible by taxi or short drive. Other access points, like the trailhead near Manzushir Monastery, involve a longer drive of around 45 minutes to an hour from the city center.

Best time to visit: The park is open year-round. Summer (June–August) offers the most comfortable hiking conditions and lush scenery. Winter (December–February) transforms the park into a snow-covered landscape, popular for winter hiking, though temperatures drop well below freezing.

Where to stay: Most visitors stay in Ulaanbaatar and visit the park on a day trip, though some ger camps operate near the park's edges for a more immersive overnight option.

Bogd Khan Uul (Mongolia): informally protected from the 12th–13th century, formally protected in 1778
Tobago Main Ridge Forest Reserve (Caribbean): formally protected in 1776, slightly earlier by formal designation alone
Yellowstone National Park (USA): established in 1872, the first area to use the specific term "national park"
Royal National Park (Australia): established in 1879, often cited as the world's second true national park by that designation

Bogd Khan Uul's claim rests on continuous protected status rather than the formal "national park" label, since that specific designation didn't exist yet in 1778.

Bring layers. Temperatures on the mountain can be noticeably cooler than in the city below.
Wear proper hiking shoes if you plan to reach Tsetsee Gun or explore trails near Manzushir Monastery, since terrain includes uneven rock.
Combine it with a city visit. Zaisan Hill and the Winter Palace Museum both pair naturally with a day exploring Ulaanbaatar.
Respect the site's sacred status. As a spiritually significant mountain, visitors should avoid loud behavior, littering, or disturbing wildlife and religious structures.
