São Miguel is often called the “green island,” but those who know it well understand it could just as easily be called the blue island. Scattered across volcanic craters, plateaus and lush hillsides, the lakes of São Miguel are among the most striking landscapes in the Azores — and one of the main reasons travellers fall in love with the island at first sight.
In this guide, we highlight the São Miguel lakes truly worth visiting, explaining what makes each one unique, when to go, and how to include them naturally in your itinerary.
The most iconic of all São Miguel lakes. Set inside a vast volcanic crater in the west of the island, the twin blue and green lakes form one of the Azores’ most recognisable views.
The best viewpoints are Vista do Rei and Boca do Inferno. On clear days, the light enhances the colours dramatically. Arrive early to avoid fog and crowds.
Combine this lake with a visit to the west coast and the natural pools of Mosteiros on the same day.
Wild, elevated and unpredictable, Lagoa do Fogo sits in the centre of the island and changes completely depending on the weather.
It’s one of the most pristine volcanic lakes in the Azores. Access may be restricted in summer, and fog can roll in quickly. When the sky clears, the landscape feels untouched and raw.
Combine your visit with a stop at Caldeira Velha, a forest-surrounded thermal area where you can relax in natural hot pools.
Here, the lake is more than scenery — it’s part of local culture. Along its shores, the famous Furnas stew is cooked underground using volcanic heat.
The atmosphere is quiet and immersive, with rising steam and the scent of sulphur in the air. Best combined with hot springs and botanical gardens.
Less known but remarkably beautiful, Lagoa de Santiago lies close to Sete Cidades yet receives far fewer visitors.
Easy access, gentle trails and a strong sense of isolation make it perfect for travellers seeking calm and authenticity.
Small and understated, located near Ponta Delgada. It’s not the most photogenic of the São Miguel lakes, but it works well as part of a relaxed day or at the start of your trip.
A good option for those who want to see a lake without long drives.
If you only have one or two days, start with Lagoa das Sete Cidades and Lagoa do Fogo. They are the most iconic and offer completely different landscapes.
With more time, Furnas and Santiago add depth and variety to the experience.
Weather changes quickly on the island, directly affecting visibility. Having the freedom to adjust your plans, swap days or follow the sun makes a huge difference.

More than a car — it’s the freedom to experience the island your way.
May to September offers a higher chance of clear skies, but also more visitors. Spring and early autumn provide a better balance between good light, fewer crowds and easier access.
