The reserve contains the Iliniza Sur, a peak capped by a permanent glacier, and the Iliniza Norte, which is non-glaciated.
The ecological gradient of the reserve covers an altitudinal range from 800 to 5,263 meters above sea level.
It is home to the endangered Andean condor and the curiquingue bird of prey.
The reserve serves as a transition zone between the Amazonian basin and the Pacific coastal plains.
The Chiltazón sector provides access to the 'Bosque de Polylepis,' one of the highest-altitude forests in the world.
It protects several endemic flora species, including the Chuquiraga flower, often referred to as the 'flower of the Andes'.
Reserva Ecológica Los Illinizas is a high-altitude protected area spanning over 149,000 hectares across the Cotopaxi, Pichincha, and Santo Domingo de los Tsáchilas provinces. The reserve is anchored by the twin peaks of the Iliniza volcano, North and South, which serve as the primary geological landmarks. The terrain includes diverse ecosystems ranging from paramo moorlands and cloud forests to high Andean forests. It functions as a critical water source for the surrounding agricultural regions and urban centers. The reserve is part of the Ecuadorian National System of Protected Areas and remains an active destination for mountaineering and ecological observation.
