Furnas do Enxofre

If you're into wild, otherworldly landscapes, Furnas do Enxofre on Terceira Island is one of those places that makes you feel like you've landed on another planet. This geothermal area is filled with steaming fumaroles, bubbling sulfur vents, and the strong scent of volcanic activity, a reminder that you're standing on an island shaped by fire. What's So Special About It? Active Volcanic Vents: Unlike some geothermal areas where the action is deep underground, here, you'll actually see steam rising from the earth as the heat escapes through cracks in the volcanic rock. It's a rare chance to get up close to nature's raw power. A Unique Landscape: The entire area is surrounded by lush green moss, ferns, and hardy vegetation that somehow thrives in the sulfur-rich soil. The mix of bright greenery and steaming vents makes for an epic photo spot. Short and Easy Walk: A well-maintained wooden walkway takes you through the fumaroles, so you can safely explore without worrying about stepping into a hot vent. It's only about a 15-minute walk, but the scenery makes it totally worth it.

Tips for Visiting

Brace for the Smell: Yep, it smells like sulfur (aka rotten eggs). It's not overpowering, but if you're sensitive to strong smells, you might want to take breaks while walking through.
Wear Sturdy Shoes: While the walkway is easy to follow, the surrounding ground can be damp and uneven, so avoid sandals if you want to explore the edges.
Go on a Cooler Day: Since there's hot steam rising from the vents, it can get a bit warm, especially in the summer. Cloudy or cooler days make for a more comfortable visit.
Pair It with Other Stops: Furnas do Enxofre is a quick visit, so it's perfect to combine with nearby attractions like Algar do Carvao (a volcano you can go inside) or Gruta do Natal, a lava tube that's also worth checking out.
