Graciosa may be the quietest inhabited island in the Azores, but it packs remarkable diversity into its 61 square kilometres. A UNESCO Biosphere Reserve since 2007, the island offers a spectacular volcanic caldera, one of the archipelago’s most accessible lava caves, thermal ocean baths, and some of the most intimate whale watching in the Atlantic. Here are the best things to do on Graciosa.

Natural Wonders
Caldeira da Graciosa
The Caldeira da Graciosa dominates the island’s southeastern corner, a massive volcanic crater measuring roughly 1.6 kilometres in diameter and plunging 270 metres deep. Its lush interior, crisscrossed with walking paths, feels like a lost world hidden inside the earth. The PR01GRA trail traces the entire rim in an 8-kilometre loop (moderate difficulty, 2.5 to 3 hours), delivering panoramic views across the caldera floor and out to the Atlantic. Access is free and the trailhead starts near the visitor centre. Wear sturdy shoes, the rim path has sections of loose volcanic gravel.
Furna do Enxofre (Sulfur Cavern)
Inside the Caldeira sits one of the Azores’ most remarkable geological features: a vast lava cave crowned by a vaulted ceiling 40 to 50 metres high, with a cold-water lake at its base and active fumaroles steaming from the walls. A spiral staircase of roughly 180 steps descends from the caldera floor into the cavern. The visitor centre at the caldera rim provides access and safety briefings. Entry costs approximately 5 to 8 EUR. Hours are typically 10:00 to 18:00 in summer and 10:00 to 17:00 in winter, closed Mondays. Access may be restricted when volcanic gas (CO2) levels are elevated, so check conditions at the visitor centre before descending.
Termas do Carapacho
On Graciosa’s south coast, natural thermal seawater emerges at around 40°C (104°F), rich in minerals, feeding a bathing complex with an outdoor pool overlooking the ocean. The contrast of soaking in warm thermal water while staring at the Atlantic is unforgettable. Entry costs roughly 5 to 8 EUR. Hours are typically 11:00 to 19:00 in summer, with reduced hours in winter. Adjacent to the complex you’ll find a natural ocean swimming pool and a small café. Arrive early in peak season to secure a spot.
Farol da Ponta da Barca
Perched on dramatic cliffs at the island’s northern tip, this 1930 lighthouse stands 71 metres above sea level beside the tiny Ermida de Nossa Senhora da Saúde chapel. The views stretch across to Ilhéu da Praia, the protected islet that serves as a seabird reserve for Cory’s shearwaters and terns. It’s one of the best sunset spots on Graciosa. The lighthouse itself is operational and not open to the public, but the surrounding area is freely accessible.
Outdoor Activities
Whale and Dolphin Watching
Graciosa offers some of the most intimate whale watching in the Azores, with small-scale operators running trips from Santa Cruz harbour. Sperm whales are resident year-round. During spring migration (April to June), blue whales, fin whales, and sei whales pass through these waters. Common dolphins, bottlenose dolphins, Risso’s dolphins, and Atlantic spotted dolphins are seen regularly. Trips cost 50 to 65 EUR per person and last 3 to 4 hours on small boats, typically zodiacs or open-deck vessels with 8 to 12 passengers. The smaller group sizes on Graciosa mean closer encounters and no jostling for rail space, a stark contrast to the larger operations on São Miguel and Pico.
Scuba Diving
The waters around Graciosa feature caves, volcanic rock formations, and reefs with visibility ranging from 15 to 30 metres. Key dive sites include Ilhéu de Baixo (submarine caves and lava arches), BaÃa da Ponta da Barca (accessible shore dive), and the reefs off Carapacho. Marine life includes manta rays (seasonal), groupers, barracuda, moray eels, and octopus. Water temperatures range from 16°C (61°F) in winter to 23°C (73°F) in summer, so a wetsuit is needed year-round. Dive operators on Graciosa are small and seasonal; verify availability before travelling.
Hiking Trails
Three official trails crisscross Graciosa’s compact landscape. PR01GRA (Rota da Caldeira) is the signature 8-kilometre caldera rim loop, moderate difficulty, taking 2.5 to 3 hours with 360-degree views. PR02GRA (Rota da Furna do Enxofre e Vulcão) is a shorter 6-kilometre route descending into the caldera and around its base, moderate difficulty. PR03GRA (Rota do Carapacho) follows the south coast for 5 kilometres on an easy to moderate trail connecting Santa Cruz to the thermal baths. For a quick climb, the short path up Monte da Ajuda above Santa Cruz rewards with panoramic town and ocean views.
Natural Swimming Areas
Porto Afonso on the west coast is a popular natural swimming area with a concrete platform and ladder access into clear Atlantic water. The natural ocean pool beside Termas do Carapacho offers a saltwater swim with thermal comfort nearby. Praia (São Mateus) on the north coast has natural rock pools that fill at high tide. Graciosa has no sandy beaches, typical of the Azores, but these swimming spots are well-maintained and popular with locals in summer.
Culture, Food and Wine
Graciosa Wine Tasting
Graciosa produces distinctive wines, especially dry white Verdelho, grown in UNESCO-recognised stone-walled currais (rectangular enclosures) that protect vines from Atlantic winds. The Adega Cooperativa da Graciosa in Santa Cruz offers tastings of the island’s wines. The vineyards around Guadalupe, in the island’s interior, are particularly photogenic with their geometric stone walls and traditional windmills. Harvest season runs through September and October.
Santa Cruz da Graciosa
The island’s capital is a classic Azorean whitewashed town of around 2,000 people. The Igreja Matriz de Santa Cruz, dating from the 16th century, combines Baroque and Manueline architectural elements. The Museu da Graciosa (Tuesday to Sunday, roughly 10:00 to 17:30, 3 to 4 EUR) covers local history, whaling heritage, ethnography, and wine-making traditions. The 16th-century Forte de Santa Cruz sits by the harbour, and the Jardim João Gomes Vieira provides a shaded central square. Pastelaria O Forno is the place to try queijadas da Graciosa, the island’s traditional star-shaped sweet cheese tarts.
Praia (São Mateus)
The island’s second-largest settlement on the north coast is a working fishing village of roughly 800 people. The ferry terminal for inter-island connections is here. The Igreja de São Mateus anchors the village, and views across to Ilhéu da Praia, a protected seabird islet, are excellent from the waterfront. Praia feels noticeably more local and less touristed than Santa Cruz.
Traditional Windmills
Red-capped traditional windmills (moinhos de vento) dot Graciosa’s landscape, particularly around Luz in the south and scattered across the interior. Unlike the whitewashed windmills on other Azores islands, Graciosa’s are distinctively red. Several have been restored and are photogenic subjects against the island’s green pastures and stone walls.
