The Amazon Rainforest - The Amazon Region and its five provinces can be geographically divided into two sub regions: the High Amazon and the Amazon Lowlands. The Highlands is comprised of the Andean foothills which slowly descend towards the Amazon River Basin. Here, you'll find the Napo, Galeras, Cutucú, and Cóndor ranges. The most impressive elevated regions of this area are in the north and include Volcano Sumaco. The Lowlands, found further to east, are home to some of the nation's most beautiful and important rivers: the Putumayo, the Napo, and the Pastaza.
The Andean Sierra - The Andes Mountain Range crosses the country from north to south. The Occidental and the Oriental Ranges are born from this mountain system as it divides in the province of Loja, forming plains and valleys along the Andean Corridor. Between the two ranges there is a plateau which reaches heights of three thousand meters. The Highlands Regions, commonly referred to as "La Sierra", is made up of ten provinces, each of which have important peaks such as Chimborazo, the Illinizas, Cotopaxi, Cayambe, and Antisana.
The Pacific Coast - Ecuador's coastal region (a.k.a. the western lowlands) is made up of fertile plains, rolling hills, and sedimentary basins traversed by a plethora of rivers that rush from the heights of the Andes to the Pacific Ocean. All five coastal provinces, encompassing 640 kilometers of coastline between them, have attractive beaches and plenty of hotels and resorts for tourists. Crisscrossed by an expansive network of rivers and home to the nation's most spectacular beaches, the provinces of Esmeraldas, Manabí, and Guayas quite impressive destinations frequented by tourists from all over the world.
