Vietnam's First & Most Biodiverse National Park

Established in 1962 by President Ho Chi Minh, Cúc Phương National Park spans over 22,200 hectares across three provinces (Ninh Bình, Hòa Bình, and Thanh Hóa). As Vietnam's oldest national park and premier ecological treasure, it is home to over 2,234 vascular plant species, 135 mammal species, and 336 bird varieties.

Unlike the tranquil river-based karst valleys of Tam Cốc and Tràng An, Cúc Phương immerses you into primeval tropical rainforest with massive canopy trees, ancient limestone caves, and world-renowned primate rescue operations.

World-Class Wildlife Conservation Centers

Before driving deeper into the jungle, your first stop near the park headquarters must be the conservation facilities:

  • Endangered Primate Rescue Center (EPRC): Dedicated to rehabilitating critically endangered gibbons, langurs (including the rare Cat Ba Langur and Delacour's Langur), and loris species rescued from illegal wildlife trafficking. Guided tours depart regularly.
  • Carnivore and Pangolin Conservation Program (CPCP): Operated in partnership with Save Vietnam's Wildlife, offering interactive education on saving the world's most trafficked mammal — the Sunda and Chinese pangolin.
  • Turtle Conservation Center (TCC): Sheltering over 600 freshwater and terrestrial tortoises across 20 distinct Vietnamese species.

The Butterfly Season Phenomenon (April - May)

If you visit Cúc Phương between mid-April and late May, you will witness one of nature's greatest spectacles in northern Vietnam: the emergence of millions of wild forest butterflies (predominantly Appias albina and swallowtails).

Butterfly Watching Tip: The butterflies congregate in dense white and yellow clouds along sunny puddle spots on the main asphalt forest road, especially after light morning rain followed by bright sunshine. Drive slowly to protect them.

Frequently Asked Questions

Do I need a private guide to trek in Cúc Phương?

For the popular Chò Tree loop and Cave of Prehistoric Man, self-guided hiking is straightforward along marked trails. For the demanding Silver Cloud Peak or overnight Muong village treks, hiring an official national park forest ranger guide is legally required.

What should I pack for Cúc Phương rainforest trekking?

Sturdy hiking shoes with grip, long socks to guard against leeches (especially during wet season), mosquito repellent containing DEET, at least 1.5 liters of water, and a lightweight rain jacket.
