El Altar, known in the indigenous Kichwa language as Kapak Urku, is an extinct stratovolcano located within Sangay National Park and is widely regarded as one of Ecuador's most striking mountains. Standing at 5,319 meters (17,451 feet), it is believed to have once been one of the highest peaks on Earth before a massive collapse roughly 500 years ago created its current horseshoe-shaped caldera. This caldera opens to the west and shelters the emerald-green Laguna Amarilla at its center, fed by hanging glaciers from the surrounding ridges. The Spanish conquistadors gave it the name 'El Altar' because its nine main peaks resemble the layout of a cathedral, with the highest point named 'El Canónigo' (The Bishop). Due to extreme technical difficulty and unstable rock conditions, El Altar is considered the most challenging climb in the Ecuadorian Andes. Trekking to the crater rim is a popular but demanding journey that features sweeping views of the pristine wilderness of Sangay National Park, a UNESCO World Heritage site.

📋 Practical info
Getting there
The journey to the volcano typically starts with a challenging multi-day trek from nearby Andean communities. Hiring local pack animals or porters is a common way to manage the demanding approach.
Best season
The drier months, generally from June to September, provide the best chances for clear views of the peaks. However, mountain weather is notoriously unpredictable and can change rapidly at any time.
Terrain & paths
Trekking to the caldera involves steep, notoriously muddy trails and significant altitude gains. The final approach to the impressive lagoon requires navigating rugged and often slippery alpine paths.
What to bring
Comprehensive alpine trekking gear, including sturdy waterproof boots and cold-weather layers, is strictly required. A high-quality sleeping bag and reliable trekking poles are also essential for this expedition.
Parking
Vehicles are securely parked at the haciendas or villages where the trek officially begins. These base areas provide the last point of reliable infrastructure before heading into the mountains.
Safety
Altitude sickness is a major risk, so proper acclimatization before attempting the trek is crucial. The isolated nature of the collapsed caldera means immediate rescue services are largely unavailable.
Time needed
A complete expedition typically demands a minimum of two to three days of strenuous hiking. Extra time should be factored in to account for severe weather delays or altitude adjustments.
