The Azores: São Miguel’s Crater Lakes, Thermal Springs & Whale Season

Timeless travel, whenever wherever.

Out in the Atlantic, around 1,500 kilometres west of Lisbon, the Azores feel like Europe at the edge of the wild. Nine volcanic islands rise from deep blue water; crater lakes fill ancient calderas, tea grows on green hillsides, and whales travel through remarkably rich waters.

For a first visit, São Miguel is a natural beginning. Here, you can spend a morning above a cloud-filled crater, an afternoon among hot springs and botanical gardens, and an evening beside the marina. The beauty is not only in the views. It’s in the island’s living volcanic landscape, and the thoughtful pace that lets you experience it.


🌿 Sete Cidades: two lakes, one remarkable caldera

At Vista do Rei, the famous panorama opens across twin lakes (one green, one blue) nestled inside the immense volcanic caldera of Sete Cidades. On a clear day, the colour contrast feels almost unreal. Hydrangeas line the roadsides, while low cloud sometimes drifts across the far rim.

Nearby, the shell of the Monte Palace hotel makes a striking, haunting photo stop. It is abandoned, not an attraction to enter: admire it from appropriate public viewpoints, and continue down to the lakeside village, where Sete Cidades feels wonderfully calm.

Follow the shoreline to the Bridge of Seven Streets, or allow extra time for a walk on the crater trails. The official Sete Cidades visitor centre shares information on local geology, walking routes and the protected landscape.

One honest note: cloud can close in within minutes. Give the caldera time, keep your schedule flexible and be willing to return later. Sometimes the view arrives in a brief, dazzling window.


🌋 Lagoa do Fogo: the wilder heights

Higher and more exposed than Sete Cidades, Lagoa do Fogo, the “Lake of Fire”, sits in a dramatic crater framed by rugged green slopes. A winding road climbs toward viewpoints, but fog, wind and changing conditions can quickly reshape the experience. Check the forecast and road access before setting out.

Below the lake, Caldeira Velha offers a lush geothermal setting with natural hot-water pools. Facilities and access arrangements can vary, so check current information before you go. On the trail, proper shoes and waterproof layers matter: mist and mud are part of island walking, not rare exceptions.

For a quieter walk, seek out Lagoa do Congro, a small green lake tucked into woodland. It’s one of São Miguel’s lovely hidden gems, and a reminder that adventure travel here often means slowing down and following a trail beneath the trees.

🍃 Tea, pineapples and the pleasure of tasting local

On the north coast, Gorreana and Porto Formoso grow and process tea on volcanic slopes: an unexpected sight in the middle of the Atlantic. They are widely known as Europe’s only commercial tea plantations. Visit for the green hillside views, a look at the production process and a cup of locally grown tea; check opening arrangements before travelling.

Near Ponta Delgada, the island’s pineapples grow slowly in glasshouses, taking around two years to mature. Visit a plantation such as Ananás A Arruda to see the distinctive growing method, then try the fruit, or a taste of pineapple liqueur. It’s a small, delicious window into how São Miguel turns its volcanic soil and mild climate into something uniquely its own.


♨️ Furnas: steam, gardens and a meal from the earth

In Furnas, volcanic activity is not hidden beneath the landscape. Steam rises from the valley, mineral springs bubble, and at Lagoa das Furnas, local cooks lower pots of cozido into the warm earth, where the stew cooks slowly for hours. Book ahead to try this island signature. You’ll taste the place in every spoonful.

Afterwards, explore the fumaroles and the botanical garden at Terra Nostra, then step into its famous iron-rich thermal pool. The water is naturally orange-brown and mineral-rich, bring an old dark swimsuit, as it may stain. For an evening soak, Poça da Dona Beija is a favourite; check its current reservation and entry rules before your visit.

Around town, locals fill bottles at natural carbonated mineral-water springs. It’s a simple, memorable ritual. So is bolo lêvedo, Furnas’s soft, lightly sweet muffin-bread, especially good alongside a meal or a quiet coffee.

🐋 Whale season: meet the Atlantic with care

More than 20 cetacean species have been recorded in Azorean waters, including sperm, blue, fin and sei whales, as well as dolphins. Sperm whales are present year-round; migrating blue and fin whales are most associated with spring, broadly March to June. Whale-watching trips generally run from spring into autumn, with April to October a useful overall season. Sightings are never guaranteed.

Choose a licensed operator that explains its approach, has a knowledgeable naturalist on board and follows local wildlife rules: careful distances, no chasing and no crowding animals. Keep a second possible boat day in your plans, especially if seeing whales is a priority. You can read more about whale and dolphin watching in Portugal.

🌊 Volcanic shores and a living landscape

São Miguel’s geothermal character shapes far more than its hot pools. Fumaroles, bubbling springs, warm bathing water and Furnas’s earth-cooked cozido are all expressions of a landscape still shaped by volcanic heat.

Along the coast, Mosteiros and Ponta da Ferraria offer natural lava formations and swimming spots; at Ferraria, geothermal warmth can mingle with seawater around low tide. Check tides and sea conditions carefully: the ocean is powerful here, and access can be slippery. Expect black sand, dark pebbles and rugged lava, not Caribbean-style beaches. At Santa Bárbara, surfers come for Atlantic waves and a broad, dramatic shoreline.

The Azores’ protected-area networks, renewable energy from sources including geothermal, wind and hydropower, and regulated wildlife experiences all contribute to a more considered visitor model. The share of electricity supplied by renewables varies by year, so it’s best understood as a substantial contribution, not a fixed promise. The region’s sustainability certification is explained by the Azores sustainability programme. Here, beautiful but never too lively is a quality worth protecting.


🏘️ Ponta Delgada: island life at an easy pace

In the capital, stroll the cobbles around Portas da Cidade, browse local produce and cheeses at Mercado da Graça, then wander toward the marina. Visit the Ananás A Arruda pineapple operation if it fits your plans. As evening settles, the marina bars invite you to linger over an espresso or a local gin.

Food across São Miguel is generous without fuss: cozido das Furnas, fresh tuna, garlic-butter lapas (limpets), and bolo lêvedo. Look out, too, for cheeses from neighbouring islands, including São Jorge. The Azores eat simply and superbly from land and sea.

For a stay, choose a boutique conversion in Ponta Delgada, a garden hotel in Furnas such as the heritage Terra Nostra Garden Hotel, or a rural lodge tucked into the green. Luxury here is understated: quiet gardens, thoughtful hosting and a view that doesn’t need dressing up.


🗓️ When to go, and how to shape your stay

For whale watching and a better chance of settled weather, consider April to October. Baleen-whale migrations make spring especially compelling; June to September are generally the warmest months. The Azores are famous for four seasons in a day, though, so pack layers, waterproofs, walking shoes and swimwear. Bring a dark, older swimsuit for Terra Nostra.

Five nights on São Miguel: settle into Ponta Delgada, explore Sete Cidades, spend a full day in Furnas, set aside a flexible day for whale watching, and use the remaining time for Lagoa do Fogo, the tea plantations or the coast.

Seven nights: give São Miguel more breathing room, then add Pico for its vineyards among volcanic stone, a UNESCO-listed cultural landscape, and Faial for Horta’s marina and the volcanic terrain of Capelinhos. Check inter-island flights with SATA Air Açores/Azores Airlines and book ahead; small aircraft mean limited seats.

There are seasonal direct UK flights to Ponta Delgada, taking roughly four hours, alongside connections via Lisbon. Routes and timetables change, so check current schedules. A hire car is the most flexible way to explore São Miguel. The euro is the currency; Portuguese is the official language, and English is widely spoken in tourism. The Azores are part of Portugal, check the latest UK government travel advice for Portugal before departure.

For summer 2027, whale-watching boats and small caldera lodges can book up early, as can Furnas thermal stays during popular shoulder-season dates. If your plans take shape late, we can help explore what remains available. Find out more about Raheem Tours or get in touch with our team.

The Azores don’t ask you to rush from one highlight to the next. They invite you to watch the mist lift, feel the warmth of the earth and listen for a whale surfacing beyond the shore.

Timeless travel, whenever wherever.
