Faial Geography: Volcanoes, Landscape & Travel Guide
A central Caldeira, young western volcanoes and a steep Atlantic coast
Faial Geography: Map, Volcanoes and Regions
Faial is an irregular pentagonal island built by several volcanic systems, with an old eastern sector, a dominant central Caldeira, the young Capelo ridge and a coast deeply connected with Horta’s harbor.
Island facts
Size, Population and Physical Form
Central volcano
Caldeira and Cabeço Gordo
The Caldeira
Faial’s dominant central crater measures about two kilometers (1.2 miles) across and roughly 400 meters (1,300 feet) deep. It is a protected reserve with restricted terrain.
Cabeço Gordo
The rim reaches Faial’s high point at about 1,042.63 meters (3,421 feet), creating a wet, windy highland distinct from the coast.
Radial slopes
Broad green slopes descend from the central volcano toward villages and sea, broken by secondary cones, valleys and streams.
Clear-day views
Pico and São Jorge may be visible from the high interior, but cloud routinely closes the panorama.
Crater vegetation
Native and introduced plant communities occupy the humid interior; visitors must stay on authorized routes to protect habitat.
Water and weather
The central elevation captures Atlantic moisture, creating more cloud and rainfall than Horta and sheltered coastal bays.
How the island grew
Ribeirinha, Caldeira, Capelo and Capelinhos
Faial formed through several volcanic stages. The Ribeirinha complex in the east represents the oldest sector, with official trail guidance placing parts of that landscape at roughly 800,000 years. The central volcano then built the island’s largest mass and Caldeira. To the west, the Capelo volcanic ridge contains around twenty cones extending toward Capelinhos.
The 1957–58 Capelinhos eruption began offshore. A temporary islet known as Ilha Nova appeared and was reworked by the sea before later activity built a cone and isthmus connected to Faial. The eruption added roughly 2 km² of new territory, although estimates vary and the exact area continues to change as unconsolidated ash erodes.
Tectonic setting
Faial, the Mid-Atlantic Ridge and the Triangle Islands
Central Group position
Faial belongs to the Central Group and forms the Triangle Islands with Pico and São Jorge.
European-plate wording
Faial is often described as a far-western European island on the Eurasian side of the regional plate boundary; this should not be confused with a simple continental coastline.
Flores and Corvo contrast
The two western-group islands lie west of the Mid-Atlantic Ridge on the North American Plate, illustrating the archipelago’s complex tectonic setting.
Pico-Faial Channel
The short channel, O Canal, shapes ferry travel, sailing, marine life and the strong visual relationship between Horta and Pico Mountain.
Graben of Pedro Miguel
Fault-controlled terrain in the east is one of the archipelago’s important geosites and appears on official Ribeirinha and Caminhos Velhos routes.
Active region
Faial remains in an active volcanic and seismic setting, even though the visitor landscape is normally stable and managed.
Coast and life
Cliffs, Lava Arches, Hydrangeas and Marine Habitat
Lajinha and Ponta Furada
Caves and lava arches show where marine erosion cuts volcanic rock; exposed edges and surge make distance essential.
Horta harbor
A sheltered southeastern bay gave Faial a port central to transatlantic shipping, cables, whaling, seaplanes and yachting.
Porto Pim and Monte da Guia
Two volcanic hills protect a curved sandy bay and create one of Faial’s most recognizable coastal forms.
Hydrangeas
Blue flowers line roads and field boundaries and support the Blue Island identity, though hydrangeas are introduced rather than endemic.
Pasture and agriculture
Moist slopes sustain green pasture and farming that remain visible across the island.
Birds and marine life
Cliffs, protected coastal areas and Atlantic waters support seabirds, cetaceans and diverse marine ecosystems.

Practical Faial Geography Tips
Keep the map uncropped
Use the complete island map to understand the central crater, western peninsula, Horta and circular coast road.
Do not infer coast weather from the Caldeira
High cloud can hide Cabeço Gordo while Horta and Porto Pim remain usable.
Stay on protected routes
Crater vegetation, native forest and Capelinhos ash are easily damaged away from designated access.
Allow for erosion
The Capelinhos coastline is geologically young and continues to change; old measurements and photos are not permanent.
Use official trail grades
Faial routes range from short easy circuits to hard linear crossings; distance alone does not show exposure.
Treat viewpoints as conditional
Wind and visibility determine whether highland stops are rewarding or safe.

Questions travelers ask
Faial Geography FAQ
How big is Faial Island?
Faial covers about 173.06 square kilometers and measures roughly 21 kilometers east to west by 14 kilometers north to south.
What is the highest point on Faial?
Cabeço Gordo reaches approximately 1,042.63 meters on the rim of the central Caldeira.
How large is the Faial Caldeira?
It is about two kilometers across and roughly 400 meters deep, with protected highland habitat around the rim and interior.
How did Capelinhos change Faial?
The 1957–58 eruption built an offshore cone and connection to the island, adding roughly two square kilometers before ongoing erosion.
Why is Faial called the Blue Island?
Hydrangeas lining roads and fields create a vivid blue summer landscape, complemented by the island’s close relationship with the Atlantic.
