What Are the Sulfur Mines?

The Sulfur Mines are a geothermal area located on the inner slopes of Sierra Negra Volcano. This active zone features vivid yellow sulfur crystals, steaming fumaroles, and rugged lava terrain, offering a window into the living geology of the Galápagos.

👉 Don’t just read about it — live it. Join a guided hike and witness the volcanic forces that shaped these islands.

Where Are They and How Do You Get There?

The tour begins in Puerto Villamil, Isabela Island. A short vehicle ride takes you to the El Cura checkpoint, followed by a moderate hike (approx. 3–3.5 km round trip) through varied volcanic ecosystems.

Along the trail, you’ll pass through humid highlands, barren lava fields, and panoramic viewpoints before reaching the heart of the caldera — one of the world’s largest volcanic craters.
