Bosques Nublados de Udima Wildlife Refuge, Cloud forest wildlife refuge in La Florida, Peru

Bosques Nublados de Udima is a 12,183-hectare wildlife refuge in the regions of Cajamarca and Lambayeque. Its main section covers the steep slopes of an escarpment that drops more than 1,000 metres from a dissected plateau to the Zaña River. Two smaller non-contiguous sections lie along the Chancay River and around the Poro Poro archaeological site. The highest point reaches 3,367 metres.

Peru's government first designated this area as a protected zone in 2010, then formally established it as a national refuge in 2011. This dual recognition reflected growing awareness of the forest's ecological value.

The village of Udima, formerly Hacienda Udima, lies about 2 km north of the refuge border at 2,365 m and had 696 inhabitants in 2017. The Zaña River leaving the refuge irrigates an agricultural valley centred on the town of Zaña, especially for sugar cane. The valley below holds pre-Columbian sites, including irrigation canals dated to 3400 BCE, possibly as old as 4700 BCE.

Visitors need a permit from the authorities before entering this refuge, and must follow specific rules to protect the ecosystem. Check access conditions and procedures before planning a visit, as regulations may change.

This refuge sits where the Andes are low enough for Amazon rainforest species to grow on the western slopes. This unusual mix of mountain and rainforest ecosystems exists in only a few places in Peru, making the area biologically distinct.
