Tumbes is a coastal region in northwestern Peru and southwestern Ecuador. Due to the region's location near the Equator it has a warm climate, with beaches that are considered among the finest in Peru. Despite its small area, the region contains a wide variety of ecosystems.
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.
