Yasuní National Park
With 668,000 hectares, it is the biggest national park in the continental region of Ecuador, covering part of the province of Orellana in the Oriente of Ecuador. It contains the greatest diversity of species in Ecuador which makes this national park one of the most important.
The site doesn't have drastic altitudinal variations, however it has several different ecosystems due to the rivers that flood certain parts of the park and create various swamps and lakes. Among the aquatic species found here are the river dolphin and the manatee, two highly threatened species. On land are indigenous communities like the Huaoranis and Quichuas and there are animals like the jaguar, peccaries, tapirs, deer, monkeys, etc.
The park was declared a World Biosphere Reserve by UNESCO and is composed of thousands of small hills that have been formed by the passing of different rivers. The ecosystem in this park is one of those with greater biodiversity on the planet, as well as being one of the most complex biological systems like the rest of the Amazon Region. The park is a biological laboratory and tourism helps the indigenous communities that live in the region.

Sumaco-Napo Galeras National Park
This park is located in the provinces of Napo and Orellana and covers an extension of 205,249 hectares. It is located in the middle of the Ecuadorian Amazon. This park is currently threatened by its strategic geographical position. Colonization and oil activity threaten to destroy the natural equilibrium of the park. This park was declared to be a World Biosphere Reserve by UNESCO.
In this area we can find giant armadillos, jaguars, bears, parakeets, peccaries, ocelots and deer. Because it is a park with altitudinal changes, access is difficult and this has allowed nature to remain almost intact.
The Sumaco volcano and the Napo-Galeras region build a network of rivers and springs that are extremely important for the development of the species in the park and throughout the Amazon.

El Cóndor National Park
This park has a size of 2,440 ha that are divided among the provinces of Zamora Chinchipe and Morona Santiago. The Condor National Park was created thanks to the action of Peru and Ecuador when they decided to create a protected area within the zone that used to be disputed between the two countries. The flora of the region is considered to be one of the richest and most diverse on the continent because the Condor mountain range, what gives the reserve its name, is older than the Andes mountain range.
