A strenuous but rewarding hike up one of Central America's most active volcanoes. Expect a steep 4-5 hour round trip (2 hours up, 2 down) on rocky trails through cloud forest that opens to dramatic crater views with a bright green acidic lake. It's a guided hike only; you'll share the trail with a small group, see interesting birds and plants on the way up, then spend 20-30 minutes at the summit soaking in the scenery before heading back down. The terrain is uneven and can be slippery after rain, so it's moderately difficult—fit beginners can manage it but expect to be tired.
Best time is the dry season from November to April, especially December-February when mornings are clearest. Avoid the rainy season (May-October) unless you enjoy mud and low visibility. Expect to pay around $80-120 per person including transport from San Salvador or La Libertad, guide, and park fees. Independent hiking isn't allowed.
Tip: Start with the early-morning departure; it gets hot and crowded later. Skip trying to combine it with Izalco or Cerro Verde in one day unless you're in great shape—the Santa Ana hike is enough. Bring plenty of water, sturdy shoes with grip, a light jacket for the top, and sunscreen. The views make the effort worth it on a clear day.
