A detailed look at the Janela do Inferno and Caldeira Velha tour

Starting Point and Itinerary Overview

The tour begins near Casa da Água, a popular starting point for exploring São Miguel’s volcanic terrain. From here, the trail sets out into what feels like a scene straight from a fairy tale — dense forest, vibrant greenery, and the distant sound of waterfalls. The highlight is crossing several tunnels—each with its own character—originally built as aqueducts. These tunnels are dark, long, and require a flashlight, making them a small adventure within the hike itself.

As you traverse the trail, you’ll enjoy breathtaking views over Lagoa and Ponta Delgada, framed by the deep blue of the Atlantic Ocean. The landscape is dotted with small valleys crossed by streams, perfect for photography, as many reviewers have noted. We appreciated how the guide pointed out local plants and fauna, adding an educational touch to the walk.

The Tunnels of Janela do Inferno

The tunnels are a standout feature. Built into the volcanic landscape, they are remnants of old aqueduct systems. As one reviewer put it, “Crossing the tunnels made the hike feel like an adventure, especially when the guides handed out flashlights.” Be prepared for some darkness and slippery surfaces, so sturdy shoes are a must. If you’re claustrophobic, it’s worth noting that the tunnels can be tight and long, so this might not be suitable for everyone.
