Sierra Negra Volcano

Getting to Sierra Negra means starting in the highlands above Puerto Villamil, and that alone surprised me — after days of beach landings and dry coastal scrub, suddenly we were in cattle pasture and cloud forest, damp and green and cool enough that I actually needed the jacket I’d packed and never used anywhere else in the Galápagos. We hired a truck to take us up the muddy track to the trailhead, bouncing around in the flatbed with a handful of other travelers, and by the time we hopped out we were solidly in the mist, unable to see more than about twenty meters ahead.

The hike itself is a couple of hours each way, mostly flat and easy underfoot, which lulled me into thinking the whole day would be gentle. Then the trail broke out of the cloud cover right at the rim, and the caldera opened up below us — ten kilometers across, one of the largest active calderas on the planet, a floor of black and rust-colored lava so vast that my brain kept trying and failing to register the scale. Lia just stood there for a solid minute without saying anything, which for her is a rare event.

We continued around toward Volcán Chico, a satellite vent on the flank of Sierra Negra, and this stretch is where the volcano stopped being scenic and started feeling alive. Steam was still hissing out of cracks in the ground in places, the rock underfoot had that hollow, brittle sound to it, and the smell of sulfur drifted through every so often on the wind. Our guide told us the last major eruption was in 2018, which suddenly didn’t feel like ancient history at all — it felt like something that had happened recently enough to still be cooling.

The walk back down felt longer than the walk up, the way descents somehow always do when your legs are tired and your brain has already checked out and started thinking about lunch. We ate ceviche in Puerto Villamil afterward with the kind of appetite you only get from a full day outdoors, and I remember thinking that Sierra Negra was the one part of the Galápagos trip that had nothing to do with wildlife at all, and somehow didn’t need to.

When to go: The dry season from June to December offers the clearest views into the caldera, since the highlands are prone to thick garúa mist for much of the rest of the year.
