The Cayambe-Coca Ecological Reserve spans more than 400,000 hectares between the Andes and the Équateur Amazon. It encompasses the Cayambe volcano — whose glaciated summit is the only point on the planet situated exactly on the equator at high altitude — and descends to the humid tropical forests of the Amazon foothills. This exceptional altitudinal gradient makes it one of Équateur's richest biodiversity zones.

Practical information at a glance

• Entrance: fee required (national park entrance fee; tariff to confirm with Équateur's Ministry of Environment).
• Attire: warm and waterproof clothing essential at altitude; sturdy hiking equipment recommended.
• Suggested duration: from one day (hike to refuge) to several days (Cayambe ascent or Amazon crossing).
• Accessibility for disabled visitors: very limited due to mountainous terrain and unimproved trails.
• Guide required: mandatory for any glacial ascent of Cayambe; strongly recommended for trails in the Amazon rainforest.

What you'll see

The reserve covers five distinct life zones: Andean páramo, cloud forest, subtropical forest, humid tropical forest, and glacial zones. Hundreds of bird species are recorded here, including the Andean condor, Andean rock cock, and numerous hummingbirds. Mammals include the spectacled bear, mountain tapir, and puma.

High-altitude lagoons — notably Laguna San Marcos — offer characteristic páramo landscapes: tufted grasses, frailejones, and near-total silence.

History and context

The reserve was established in 1970, making it one of Équateur's first protected areas. Its name combines the Cayambe volcano, the highest peak in the Imbabura-Pichincha province, and the Río Coca, a major waterway flowing through the Amazon foothills. It is administered by the Ministry of Environment (MAE) and is part of the national protected areas system (SNAP).

The indigenous Kayambi and Kichwa communities live on the periphery and maintain agricultural and ritual practices linked to the páramo that span centuries.

Highlights of your visit

Cayambe volcano and its equatorial glacier

At 5,790 meters, Cayambe is Équateur's third-highest peak. Its glacier is the only one in the world crossed by the equatorial line. The technical ascent requires serious preparation and a certified guide. The Ruales-Oleas-Berge refuge, located around 4,600 m, is the usual starting point.

Laguna San Marcos

Accessible from the Papallacta sector, this high-altitude lagoon is surrounded by pristine páramo. The round-trip hike is feasible in a day for hikers in good physical condition. Birdlife is particularly visible early in the morning.

Papallacta hot springs

At the southeastern edge of the reserve, Papallacta is renowned for its thermal springs fed by volcanic activity. It's a natural stopping point before or after a hike in the páramo.

The Amazon foothills

The reserve's eastern slope descends into tropical rainforest. The Reventador sector and the San Rafael waterfall area (before its partial collapse in 2020) illustrate the spectacular transition between the Andes and the Amazon.

Photography tips

Morning light is ideal in the páramo: low mists, golden hues on the grasses, and reflections on the lagoons. At altitude, clouds accumulate rapidly after 10–11 a.m.; start early. For the Cayambe glacier, a nighttime ascent is standard — sunrise photos from the summit are striking but require camera equipment adapted to extreme cold.

No known photography restrictions in the reserve, except respect for local communities.

Location and access

The reserve spans the provinces of Pichincha, Imbabura, Napo, and Sucumbíos. The main entry points are:

• Cayambe sector: from the town of Cayambe (approximately 1.5 hours from Quito via the Northern Panamerican Highway), then trail to the refuge.
• Papallacta sector: from Quito via the Quito–Baeza road (approximately 2 hours), accessible by bus or private vehicle.
• Amazon sector: from Lago Agrio or Baeza depending on the target area.

A 4x4 vehicle is recommended for interior trails. Local agencies in Cayambe and Quito offer transfers and certified guides.

Nearby attractions

• Papallacta thermal springs — volcanic hot springs at the reserve's edge, ideal after a high-altitude hike.
• Town of Cayambe — known for its bizcochos (traditional biscuits) and Kayambi indigenous market.
• Historic center of Quito — capital approximately 1.5 hours away, the logical starting point for organizing your visit.
• Otavalo market — renowned indigenous artisan market, accessible from the reserve's northern side.
