Normal Route (Iliniza Sur)
Iliniza Sur has a documented normal ascent route, but it is significantly more difficult and serious than the north peak. The climb is a true mountaineering route with steep, exposed rock and mixed terrain rather than a simple walk-up. Route-finding can be important, especially in poor visibility. The mountain is known for loose rock and objective hazards from weather and altitude. Many climbers treat it as a more technical companion peak to Iliniza Norte. The route is typically described in Ecuador climbing references as the standard way to the summit.
