A waymarked loop around the rim of Faial's 400-metre-deep volcanic caldera, through cedar and heather cloud-forest with viewpoints down into the crater floor.
The trail starts at the Caldeira do Faial Natural Reserve car park on the EN2-1, reached by car from Horta in about 15 minutes; there is no scheduled bus service to the trailhead, and access requires no permit though the reserve is a protected area with signed rules on staying to the path. The loop covers 6.5 km with about 250 m of cumulative elevation gain, rated moderate, following the rim of Faial's volcanic caldera, a crater roughly 400 m deep and 1.5 km across formed over 300,000 years of eruptions. The path is packed dirt with sections of boardwalk protecting sensitive cloud-forest vegetation, and surfaces can be muddy and slick given the caldera's frequent cloud cover; shade comes from native cedar, heather, and juniper cloud-forest along most of the route, while exposure is limited to the fenced viewpoints looking directly down into the crater. Landmarks include several miradouros overlooking the crater floor, where the vegetation is dense forest quite different from the exposed rim, remnants of the crater's flat centre used briefly for pasture, and, weather permitting, views extending toward Faial's coastline. A shorter option covers the eastern half of the rim only, returning via the access road, for a walk of roughly 4 km. There are no refuge huts or water sources on the trail. Because the caldera sits at over 1000 m and traps cloud easily, temperatures are noticeably cooler and wetter than at sea level, and waterproof layers are advisable even when Horta itself is dry.

Highlights
- Circling the rim of Faial's 400-metre-deep volcanic caldera
- Viewpoints looking straight down into the forested crater floor
- Walking through native cedar, heather, and juniper cloud-forest
- Contrast between the exposed rim and the sheltered crater interior
- Coastal views of Faial on clear stretches of the rim
Tips for visiting
- Bring a waterproof jacket, as the caldera frequently holds cloud and drizzle even on dry days at the coast
- Wear boots with grip for muddy boardwalk and dirt sections after rain
- Stay on the marked path, as the reserve protects sensitive native cloud-forest vegetation
- Allow extra time in poor visibility, since fog can obscure the trail markers on the rim
- Consider the shorter eastern-half option if time or weather is limiting
When to visit
Mid-morning visits after early cloud has a chance to clear give the best odds of visibility into the crater.
Accessibility
Boardwalk sections near the main viewpoints could accommodate a sturdy stroller with assistance, but the full loop is not wheelchair-accessible due to uneven dirt sections elsewhere.
Frequently asked questions
How deep is the Caldeira do Faial?
The volcanic crater is roughly 400 m deep and about 1.5 km across, formed over some 300,000 years of eruptions.
Is the trail often foggy?
Yes, the caldera sits above 1000 m and frequently holds cloud, so visibility from the rim viewpoints is not guaranteed.
Is there a shorter route around the caldera?
Hikers can walk the eastern half of the rim and return via the access road for a shorter loop of about 4 km.
Is the crater floor accessible?
No, the crater interior is protected native forest and is viewed only from the fenced rim viewpoints, not entered directly.
