Adventure hike through Terceira's interior

The experience

Three hours on foot through Terceira's interior brings you to three distinct natural features: Lagoa do Negro, the volcanic cone of Pico do Gaspar, and the volcanic domes that give the trail its name. The route is built around the geology itself. You are walking through the island's volcanic landscape, not past it. A live guide in English, Spanish or Portuguese leads the way and explains what you are standing in front of.

Pickup from your hotel is included, and the guide meets you in an air-conditioned vehicle before the hike begins. The trail itself is rated medium to difficult, which means sustained climbing and uneven ground. You need a moderate level of fitness to complete it comfortably. The three-hour duration is the actual walking time, not a round-trip estimate that includes transport.

Personal accident insurance is included in the booking. The operator does not recommend this hike for travelers with spinal injuries, pregnancy, or cardiovascular conditions that limit exertion.

Is this one for you?Small groups work best on a trail this steep and sustained. You move at one pace with your guide and the other hikers. Book this if you want to walk into the volcanic interior rather than view it from a vehicle, and if you have the fitness for three hours of climbing on uneven ground.
