Cúc Phương National Park (Vietnamese: Vườn quốc gia Cúc Phương) is located in Ninh Bình Province, in Vietnam's Red River Delta. Cuc Phuong was Vietnam's first national park and is the country's largest nature reserve. The park is one of the most important sites for biodiversity in Vietnam.
In 1960 Cúc Phương was made into a forest reserve and in 1962 Cúc Phương National Park was consecrated by President Ho Chi Minh. Human habitation in Cúc Phương dates back long before the park’s creation, 7,000-12,000 years ago. Artifacts from that time have been found in numerous caves within the park, including human graves, stone axes, pointed bone spears, oyster shell knives, and tools for grinding. In 1789 the Quen Voi section of the park was the site of a major battle in the civil war between Nguyễn Huệ and Thăng Long. More recently, conflicts have emerged between the government and 2,500 Muong ethnic minority tribesmen who live, farm, and hunt in the park. In 1987, 500 Muong were relocated outside of the park because of issues over poaching and land use.
Cúc Phương is situated in the foothills of the northern Annamite Range. The park consists of verdant karst mountains and lush valleys. Elevation varies from 150 meters (500 feet) to 656 m (2,152 feet) at the summit of May Bac Mountain, or Silver Cloud Mountain. The limestone mountains house numerous caves, many of which are accessible for exploration.
The average temperature in Cúc Phương is 21 Celsius (70 Fahrenheit), with a mean winter temperature of 9C (48F). High temperatures can reach above 30C (85 F) and lows are just above zero (32 F). At the low elevations in the valley the temperature is hot and humid while at higher elevations the temperature drops and frostbite is a threat. On average it rains more than 200 days a year and the average annual rainfall is 2,100mm (7 feet). The dry season is November to February, the driest months being December and January.
