Tumbes Region - Geography

Geography

The Tumbes Region is bordered by the Ecuadorian provinces of El Oro and Loja on the east; Peru's Piura Region on the south; and by the Pacific Ocean on the north and west.

Morphologically, four zones can be defined in the region: the delta of the Tumbes and Zarumilla rivers; an alluvial plain north of the Tumbes River, with dry, low-depth ravines; ancient terraces that have been strongly eroded in the Máncora area; and the Amotape mountain range in the east and south, ending at El Barco Mountain. The delta of the Tumbes river is shallow, and when the tide is low, little sandy keys show up, which get covered by mangrove vegetation. Despite its small area— it is the second-smallest region in Peru— Tumbes has a great variety of ecosystems: mangroves, dry forests, the only coastal tropical forests in Peru, and a rich and warm sea. Around 50% of the region's territory is covered by three protected natural areas: the Manglares de Tumbes National Sanctuary (which is part of the Gulf of Guayaquil-Tumbes mangroves), the Cerros de Amotape National Park and the Tumbes Reserved Zone.
