The Azores (Açores) are a chain of nine volcanic islands scattered across the mid-Atlantic, roughly 1,400 km west of mainland Portugal. Known for crater lakes, dramatic sea cliffs, thermal springs, and green pastureland, the archipelago offers whale watching, hiking, and diving in a landscape often compared to Ireland and Hawaii combined. Ponta Delgada, on São Miguel, is the archipelago's largest city and main gateway.

1
Miradouro da Vista do Rei (Sete Cidades)
The most famous viewpoint in the Azores, perched on the southern rim of the Sete Cidades caldera at roughly 656 meters above sea level. It overlooks the twin crater lakes, Lagoa Azul and Lagoa Verde, which appear blue and green side by side inside the same volcanic basin. An abandoned mid-century hotel, the Monte Palace, stands beside the viewpoint and is a well-known photo subject in its own right.
Tip: Arrive shortly after sunrise for the clearest views before cloud fills the caldera · Bring a jacket even in summer, since the rim is exposed and often windy · The Monte Palace Hotel building is not officially open; view it from outside only · Combine the stop with a drive down to Lagoa Azul for a lake-level perspective · Parking fills quickly with tour buses by mid-morning in high season
-
2
Lagoa do Fogo
A crater lake sitting inside a dormant volcano in the Serra de Água de Pau, part of a protected nature reserve near the geographic center of São Miguel. The lake is one of the highest and least developed of the island's crater lakes, ringed by steep, largely untouched slopes, and reachable by a marked hiking trail down to its shore.
Tip: Check the access road status before driving up, since it can close in poor weather · Visit in the morning, as cloud typically fills the crater by afternoon · Wear sturdy shoes for the shoreline trail, which is steep and can be muddy · Bring water for the hike down, since there are no facilities at the shore

Terra Nostra Park
A historic botanical garden in the Furnas valley dating to the 18th century, spread across more than 12 hectares of subtropical planting, camellia collections, and a large thermal swimming pool fed by iron-rich, mineral-warm spring water that stains the water a distinctive orange-brown. Visitors can walk the garden paths and bathe in the heated pool on the same ticket.
Tip: Bring a swimsuit and a spare towel or change of clothes, since the iron-rich water can stain fabric · Rent a towel on site if traveling light, since the mineral water is not ideal for personal towels · Visit on a weekday morning for the quietest pool and paths · The pool water is warm year-round, so a swim is worthwhile even in cooler months
-
4
Poça da Dona Beija
A set of open-air thermal pools fed by natural hot springs on the edge of Furnas, landscaped with small waterfalls and changing facilities. The iron-rich water runs warm year-round, and the pools are popular with both visitors and locals for a soak after exploring the surrounding valley.
Tip: Bring a swimsuit and towel, and expect the mineral water to stain light fabrics · Visit early morning or after sunset to avoid the midday crowds · Lockers are available for valuables; bring small change if needed · Combine with other Furnas sights, such as Terra Nostra Park, on the same day
-
5
Caldeira Velha
A forested thermal park on the lower slopes of the Lagoa do Fogo volcano, centered on a warm waterfall that cascades into a natural bathing pool ringed by ferns and hydrangeas. It is one of the more scenic hot-spring sites on São Miguel, set directly beside the main road up to Lagoa do Fogo.
Tip: Visit on a weekday morning before tour groups arrive · Bring water shoes, since the pool floor is uneven volcanic rock · Check ahead in wet weather, as the park can close for maintenance after heavy rain · Changing facilities are basic, so bring a towel and a bag for wet clothes
-
6
Gruta do Carvão
A lava tube running beneath the streets of Ponta Delgada, formed by a volcanic eruption from the Picos volcanic system thousands of years ago. It is one of the longest known urban lava tubes in the world and is visited on guided walks that explain the island's volcanic formation.
Tip: Book ahead, since guided tours run in small groups with limited daily capacity · Wear closed, sturdy shoes for the uneven tunnel floor · Tours are conducted in Portuguese and English; confirm the language on booking · Bring a light layer, as the tunnel stays cool year-round
-
7
Portas da Cidade
The three-arched 18th-century marble gateway that once formed the ceremonial entrance to Ponta Delgada from the sea. It now stands at the head of Praça Gonçalo Velho Cabral, framing the town hall and serving as the traditional starting point for exploring the city's historic center.
Tip: Visit in late afternoon for the best light on the marble facade · Combine with a walk through the surrounding historic center · The square gets busy during evening hours when cafés fill up · No ticket or booking is needed, since it is an open public landmark
-
8
Miradouro da Ponta do Sossego
A terraced garden viewpoint on the rugged northeastern coast of São Miguel, laid out over several levels of hydrangea-lined lawns overlooking sheer sea cliffs and the open Atlantic. It is considered one of the island's most dramatic coastal panoramas.
Tip: Visit in the afternoon for the clearest coastal visibility · Combine with other Nordeste-area viewpoints on a north-coast driving route · Summer brings the hydrangeas into full bloom for photography · Wear sturdy shoes, since the terraces involve steps between levels
-

Angra do Heroísmo Historic Centre (UNESCO)
The historic core of Terceira's capital, inscribed as a UNESCO World Heritage Site in 1983 for its well-preserved layout as a major Atlantic port town from the Age of Discovery onward. Streets of pastel merchant houses, Baroque churches, and 16th-century fortifications survive from the era when Angra was an obligatory stop for fleets crossing between Europe, Africa, and the Americas.
Tip: Walk the core in the morning before midday heat sets in · Individual monuments and churches keep their own separate hours, so check ahead for specific sites · Return in the early evening to see illuminated facades · Combine with a walk or drive up Monte Brasil at the edge of the historic center
-
10
Algar do Carvão
A dormant volcanic chimney on Terceira that visitors descend into by stairway, reaching almost 100 meters below ground through a wide vertical cave chamber hung with rare stalactites formed from silica rather than the usual limestone. A small lake sits at the bottom of the chamber, and daylight filters down through the open crater mouth above.
Tip: Arrive early in the opening window, since visitor numbers inside the chamber are limited · Wear non-slip shoes, as the stairway can be damp · Check reduced October-December hours before planning a visit · Bring a light jacket, since the cave interior stays cool

Tips for visiting attractions
Make the most of your sightseeing time.
Rent a car on each island, since public transport between rural attractions is limited
Weather changes quickly between islands and even between the coast and the crater interior, so pack layers and rain gear year-round
Book inter-island flights or ferries with SATA/Azores Airlines or Atlantico Line well ahead in summer
Many volcanic caves and craters are only reachable by unpaved or narrow roads, so allow extra driving time
Register in advance for the Montanha do Pico climb, as daily numbers are limited and a guide is recommended
Thermal pool water is naturally iron-rich and can stain light-colored swimwear
Frequently asked questions
What is the best time of year to visit the Azores for sightseeing?
Late spring through early autumn, roughly May to October, offers the most reliable weather for hiking, crater viewpoints and outdoor swimming
Do I need a car to see the main attractions?
Yes, for most islands. A rental car is the most practical way to reach craters, thermal pools and coastal viewpoints outside the main towns
Can all nine islands be visited on one trip?
It is possible with inter-island flights or ferries, but most visitors focus on two or three islands, commonly São Miguel plus Terceira, Faial or Pico
Are the volcanic caves and craters safe to visit independently?
Caves such as Algar do Carvão and Gruta do Carvão require staffed, guided or ticketed access; open-air craters and viewpoints can generally be visited independently on marked paths
