Tumbes National Reserve, Protected natural area in Province of Zarumilla, Peru.

Tumbes National Reserve is a protected natural area covering about 19,000 hectares of Pacific tropical forest in Zarumilla Province. The landscape includes hills, flat plains, and seasonal dry woodlands located near the Ecuador border.

In 1957 the government created the Tumbes National Forest, covering 75,102 hectares, to regulate logging that had already been intensive since the 1940s. A 1974 law banned timber extraction except for very mature trees, and UNESCO included the forest in the Noroeste Biosphere Reserve in 1977. A 1994 decree turned the former forest into the Tumbes Reserved Zone to protect Pacific tropical forest; on 7 July 2006 part became the national reserve, while the highest-priority sector was merged into Cerros de Amotape National Park.

The reserve's name comes from the Tumbes region, and its forest has been worked for honey and timber since the 1940s. Today the reserve is zoned to allow traditional land use in part of its area, while wood extraction, wild honey collection and hunting remain among the pressures authorities try to control.

Visitors need a four-wheel-drive vehicle to access the reserve, as roads can be challenging and difficult during heavy rain. The location is approximately 51 kilometers northeast of Tumbes city via San Juan de la Virgen and Matapalo.

Bats are the reserve's most diverse mammal group, with 35 of its 67 mammal species. The reserve also protects reptiles such as the American crocodile and the eyelash viper, plus lizards of the genus Dicrodon, a mix of dry-forest and tropical species.
