Izalco is visible from the rim of Cerro Verde National Park and makes a formidable visual impression — a stark, ash-grey cone rising above the surrounding forest, looking actively hostile even in repose. The hike to the summit of Izalco is steeper and more demanding than the Santa Ana Volcano trail, with loose volcanic rock making the ascent tiring.
Both volcanoes can be combined in a long day from Cerro Verde, though most visitors choose one or the other. Izalco's barren surface and historical significance as a navigation landmark make it the more dramatic of the two. Cerro Verde National Park, about 20 km south of Santa Ana.
