What to Do in São Miguel: Complete Guide to the Green Island of the Azores
São Miguel is the most diverse island in the Azores: impossibly blue and green volcanic lakes, bubbling hot springs, subtropical gardens and black sand beaches — all within 65 km. This guide covers everything you need to know to make the most of your visit, whether you have three days or a full week.

If there is one island in Portugal capable of stealing your breath on the first bend of the road, that island is São Miguel. The largest of the nine Azorean islands is also one of the most diverse: within just 65 km you will find volcanic lakes of an impossible blue and green, bubbling hot springs, subtropical botanical gardens, black sand beaches and a vibrant capital. It is no wonder it is known as "the green island." This guide covers everything you need to know to make the most of a visit to São Miguel, whether you have three days or a full week.
Ponta Delgada: the capital worth visiting
Most visitors land in Ponta Delgada and this is where the adventure begins. The historic centre is compact and very easy to explore on foot. Start at the iconic Portas da Cidade, the 18th-century baroque arch that is the capital's most recognisable landmark, and walk on to Praça do Município with its buildings of black volcanic stone — an elegant contrast with the whitewashed walls.
The Igreja Matriz de São Sebastião, with its 15th-century facade, is one of the oldest in the Azores and deserves a quick visit inside. Right next door you will find the Mercado da Graça (1848), perfect for an Azorean breakfast of massa sovada, Queijo de São Jorge and Pico butter.
In the afternoon, make time for Jardim António Borges — a 19th-century romantic garden with giant thujas, tree ferns and an almost magical atmosphere that few tourists know about. For shopping, Rua Marquês da Praia e Monforte concentrates the best shops selling regional products, from passion fruit liqueurs to embroidery and ceramics.
Tip: Take an evening stroll through the breweries and taverns of Bairro da Matriz — the atmosphere starts early and is very authentic.
Lagoa das Sete Cidades: the Azores' most iconic photograph
About 25 km northwest of Ponta Delgada lies what is probably the most photographed landscape in the Azores: Lagoa das Sete Cidades. This volcanic caldera shelters two lakes — Lagoa Azul and Lagoa Verde — separated by a stone bridge. The difference in colour between the two is real, caused by variations in light and angles of solar incidence.
The Vista do Rei viewpoint is the unmissable stop: a 180-degree panorama over the entire caldera that will leave you speechless. But do not stop there — Boca do Inferno and Grota do Inferno offer even more dramatic angles and far fewer visitors.
If you are up for a walk, the PR3-SMI trail descends from Vista do Rei to the village of Sete Cidades over 7.7 km (about 2 hours). It is a low-difficulty route and completely worth it. Once down there, you can hire a kayak or stand-up paddleboard and explore the lakes from a different perspective.
Tip: Fog is very common in this area, especially in the morning. If you arrive and cannot see anything, do not despair — wait an hour or go up to the viewpoint in the late afternoon. The sunset light over the caldera is spectacular.
Lagoa do Fogo: the wildest of the lakes
If Sete Cidades is the famous lake, Lagoa do Fogo is the wild one. Hidden in the interior of the island at 580 metres altitude, this nature reserve fills the Água de Pau volcano crater and has waters of such intense blue they seem dreamlike. The surrounding vegetation is dense and almost untouched, with endemic Azorean species found nowhere else in the world.
During summer (mid-June to end of September), access to the lake is exclusively by shuttle bus between 9am and 7pm — car parking is prohibited to protect the ecosystem. The ticket costs €5 per person.
The PRC02-SMI trail is an 11 km hike taking you from the village of Praia to the lake shore. It is moderately demanding but extraordinarily beautiful — allow 4 to 5 hours. If you prefer something shorter, the roadside viewpoint already offers a fantastic view.
Tip: The weather changes very rapidly near the lake. Always bring a rain jacket, even if the day starts sunny.
Furnas: where the earth cooks dinner
The Furnas valley is, for many people, the highlight of a visit to São Miguel. Here the earth truly boils: the caldeiras are fumaroles and hot springs that bubble at temperatures between 66 °C and 93 °C, releasing sulphurous vapours in a landscape that seems from another planet.
But the real spectacle happens at lunchtime: Furnas Stew is a stew of meat, vegetables and sausages cooked buried in the volcanic soil for 6 to 7 hours, absorbing the geothermal heat of the earth. Around noon, the village restaurants go to the caldeira shore to unearth their pots — a ritual you cannot miss. The flavour is unique, smoky and rich, completely different from any stew you will have tasted before.
Beyond the caldeiras, Furnas has Terra Nostra Park — a 12-hectare botanical garden with over 600 species of tropical and subtropical plants, giant bamboo tunnels and the Azores' most famous thermal pool: a basin of iron-rich water of an orange colour, naturally heated to 37 °C. Taking a dip here at the end of the day is an experience beyond price.
If you prefer something more accessible, Poça da Dona Beija is the island's most popular thermal complex, with five outdoor hot pools surrounded by tropical vegetation, open until 11pm. Perfect for a night-time swim under the stars.
Caldeira Velha: the best-kept secret
30 minutes' drive from Ponta Delgada, Caldeira Velha is a nature reserve with warm waterfall pools where you can swim. The water is a greenish colour and reaches 40 °C — ideal after a hike. Entry costs a few euros but is worth every cent. Go early in the morning to avoid queues.
Gorreana Tea: Europe's only tea plantations
In the northeast of the island, Gorreana is a name every tea lover should know: it is the oldest tea plantation in Europe and one of the very few that still produces tea outside Asia. The visit is free and you can see the entire production process, from field to packaging, in a factory operating since 1883. At the end, there is a tea tasting with breathtaking views over the sea. An unmissable stop when exploring the north of the island.
Ilhéu de Vila Franca do Campo: Portugal's most beautiful natural pool
About 1 km from the south coast, the Ilhéu de Vila Franca do Campo is a submerged volcanic rim that emerged from the ocean thousands of years ago, today forming one of the most spectacular natural pools in the world. To get there you need to take a boat from Vila Franca do Campo marina (10-minute journey) and places are limited — book in advance in summer.
The interior of the islet is a lagoon of crystal-clear water with a white sand floor, surrounded by walls of volcanic rock. Swim, snorkel, or simply float — it is impossible not to fall in love.
Whale and dolphin watching
São Miguel is one of the best places in the world to spot dolphins and whales in the wild, thanks to its location in an area where Atlantic currents converge. Trips leave from Ponta Delgada harbour and last an average of 3 hours.
São Miguel has a deep history of connection with whales — whaling was for centuries one of the island's main economic activities — and today that culture has transformed into a responsible ecotourism industry. The best time is spring and summer, but common dolphins and bottlenose dolphins are spotted year-round. Sperm whales, humpback whales and even orcas appear regularly in spring.
São Miguel's beaches
São Miguel is not an island of white sand beaches — here the sand is black or grey, of volcanic origin. But that does not make the beaches any less beautiful; on the contrary, the contrast between the dark sand, the intense green of the vegetation and the blue of the Atlantic creates a unique colour palette.
Praia do Milheiral (near Lagoa) is one of the most popular. Praia de Mosteiros, at the western tip of the island, is considered one of the most beautiful, with its natural pools among the rocks and an epic sunset over the sea stacks. Praia de Santa Bárbara is the surfers' favourite, with consistent waves throughout the year.
Gastronomy: eat like an Azorean
Azorean cuisine is generous, honest and full of flavour. Beyond the now-famous Furnas Stew, there are other dishes you cannot miss.
Bife à regional is an Azorean beef steak in a wine and chilli sauce that locals eat at breakfast, lunch and dinner without hesitation. Alcatra from Pico Island and fresh Atlantic fish stew are unmissable if you enjoy seafood and Atlantic fish. And grilled limpets with butter and garlic are a rite of passage for any visitor.
For dessert, try the Dona Amélia from Angra do Heroísmo, honey biscuits and queijada da vila. To drink, Pico's vinho de cheiro and Cerveja Especial dos Açores are the local favourites.
Getting around São Miguel
The island has public transport (buses), but for freedom of exploration the ideal is to hire a car. Roads are generally good, although some mountain roads are narrow and winding — drive slowly and enjoy the landscape. There are also many tour operators organising full-day excursions to the main attractions.
When to visit
The best time is between May and September, with temperatures between 20 °C and 26 °C and long days. May is particularly special: the island fills with blue and pink hydrangeas bordering every road, and the Festa do Senhor Santo Cristo dos Milagres takes place in Ponta Delgada — one of Portugal's largest religious festivals.
Summer is busier and warmer. Autumn and winter are more humid but the island never loses its beauty, and prices are significantly lower.
