View from the Boca do Inferno viewpoint over Sete Cidades: Lagoa de Santiago in its small crater, the twin lakes and the village behind Hikers on the narrow crater-rim path to Boca do Inferno, the green slope falling away to the lakes on both sides Lagoa Verde in Sete Cidades under low cloud, the crater walls disappearing into fog

Sete Cidades

In the morning the caldera lies open: two lakes, one blue, one green.

Up top you walk the edge between the craters.

Around noon the cloud arrives – and it is all gone.

As of 22 September 2026Everything open, everything free – except the hotel

Sete Cidades is the 5 km (3 mile) wide caldera at the western end of São Miguel, with the twin lakes Lagoa Azul and Lagoa Verde at 260 m (850 ft). There is no ticket, no guide requirement, no opening hours. CIVISA lists the volcano with no alert (V0) on 22 September 2026. The practical hurdles are fog, parking and a hotel ruin you are not allowed to enter.

Open

Vista do Rei and Boca do Inferno

Both viewpoints are accessible around the clock, free, with parking. Vista do Rei is wheelchair accessible and has restrooms. Boca do Inferno is a 15–20 minute walk from the lay-by on the EN9-1A.

The experienceLooking into the caldera

You drive up the ER9-2ª from Ponta Delgada, 25 minutes through pastures and hydrangea hedges, and suddenly the road ahead is missing: the ground drops 400 m (1,300 ft) into a basin holding two lakes. One mirrors the sky, the other the walls.

At Vista do Rei you stand next to the gray block of the Monte Palace and look at both lakes and the bridge that separates them. Four kilometers (2.5 miles) further east, at Boca do Inferno, a third lake joins in: Lagoa de Santiago in its own small crater, far below the rocky spur you are standing on.

Down in the village the lake is a shore with a picnic area. You can rent a kayak and paddle under the bridge from the blue lagoon into the green one. Up on the crater rim it is windy, there is no shade, and the view changes every few minutes – sun, cloud, sun.

That is the thing about Sete Cidades: the caldera makes its own weather. What is a postcard at nine is a white wall at eleven. Which is why the first tip on this page is not about parking but about the webcam.

The rulesFour things to know before you go

There is no reservation and no fee. What there is: a car park with a time limit, a building you may not enter, a bus that does not go where everyone wants to go – and fog.

1

Parking: 20 minutes at Vista do Rei

Right at the viewpoint in front of the ruin there is a small short-stay car park with a 20-minute limit – for photos. If you stay longer or hike the PR3SMI, park at the larger lot at the junction behind it. Tour buses arrive in the morning, so come early.

2

Monte Palace: from outside only

The hotel is private property. The main entrance has been walled up; inside, railings are missing and elevator shafts stand open. Entry is prohibited and life-threatening. The best view of the ruin is from Vista do Rei anyway.

3

The bus goes to the village, not the viewpoint

Lines 205–208 of Auto Viação Micaelense take about an hour from Ponta Delgada and end in the village of Sete Cidades at 260 m. There is no bus stop at Vista do Rei: from the village it is 2 hours up the PR3SMI, or a taxi.

4

Webcam first, then drive

The caldera clouds over as the morning goes on. Check the 'Sete Cidades Cumeeiras' webcam on spotazores.com before you leave and be at the top before 10 am. If it is white up there, go to the village or the shore first – the sun is often out below.

Good to knowGetting there, best time, tips

Getting there

Without a car: Auto Viação Micaelense, lines 205–208 from Ponta Delgada (stop 'Turismo' on the waterfront road) to Sete Cidades, about 1 hour; on weekdays five departures according to third-party timetables (8:25 am, 10:40 am, 3:00 pm, 5:30 pm, 6:50 pm), fewer on weekends, some with a change in Várzea or Ramal dos Mosteiros. The buses go to the village, not to Vista do Rei – from there it is a 2-hour walk up the PR3SMI or a taxi.

By car: From Ponta Delgada on the ER9-2ª via Relva and Feteiras up to Vista do Rei, about 20 km (12 miles), 25–30 minutes. Vista do Rei: small short-stay car park (20 minutes) right at the viewpoint, larger car park at the junction behind it; arrive early, tour buses in the morning. Boca do Inferno: gravel lay-by on the EN9-1A ('Lagoa do Canário'). Village: free car park at the picnic area on the lake shore. Leave nothing visible in the car.

  • From Ponta Delgada · 25–30 minutes by car, about 1 hour by bus
    Car on the ER9-2ª to Vista do Rei; bus 205–208 to the village
  • From Ponta Delgada Airport (PDL) · about 25 minutes

Best time to go

Before 10 am: the caldera has its own microclimate and fills with cloud as the morning goes on; clear days often follow fronts with northeasterly wind. April to June are statistically the most reliable months (plus hydrangea bloom from June), September/October the quietest. Check the 'Sete Cidades Cumeeiras' webcam on SpotAzores before driving up – if it is foggy on top, go to the village or the lake shore first.

Who it suits

Children
Very good: viewpoints with no effort, flat lake shore, picnic area in the village, kayaks from age 5 with a life vest. Watch for drop-offs on the crater rim (PR4SMI) and at Boca do Inferno; the hotel ruin is off limits for children.
Minimum age
none; kayak from age 5 (Futurismo)
Fitness
Viewpoints: none. PR3SMI easy (7.5 km / 4.7 miles, downhill), PR4SMI moderate (11.7 km / 7.3 miles, exposed, little shade). Combining both trails makes a half-day hike.
Heart and lungs
no volcanic gases in the caldera; expect cold in the wind on the crater rim
Wheelchair
Vista do Rei is officially wheelchair accessible with restrooms and parking; the lake shore in the village is flat; Boca do Inferno and the hiking trails are not suitable
Dogs
no published rule; usual on the trails on a leash
Clothing
Layers and a rain jacket year-round – the crater rim is often in fog and wind even when it is sunny below; in summer sun protection (no shade on PR4SMI)
Footwear
Viewpoints: anything. Trails: sturdy shoes, the descents into the village are slippery after rain (official warning).

Tips you will need on site

  • Check the 'Sete Cidades Cumeeiras' webcam (spotazores.com) first, then set off – and be at the top before 10 am.
  • Use the 20-minute short-stay car park at Vista do Rei only for photos; for the PR3SMI or a longer stay, park at the junction behind it.
  • Boca do Inferno is the better view: 15–20 minutes on foot from the 'Lagoa do Canário' lay-by on the EN9-1A. Read the sign at the gate first – if you park inside after the gate closes, you are stuck.
  • Photograph the Monte Palace from outside only. The building is private property, fenced or walled off, with open elevator shafts and no railings; entry is prohibited.
  • The bus goes to the village, not to the viewpoint: without a car, plan the PR3SMI from the bottom up or a taxi.
  • Rent a kayak on the lake shore in the village (about €15 per two-seat kayak per hour) and paddle under the bridge from the blue lake into the green one.
  • Both trails end in the village and are one-way – sort out the return (taxi, second car, bus) beforehand.
  • Crater rim means wind and changing weather: a jacket even in summer, sturdy shoes for the slippery descents.

A short history

  • According to the Azores Geopark the caldera formed by collapse about 36,000 years ago; the English Wikipedia describes three collapse phases 35,700, 28,750 and 15,740 years ago. Diameter about 5.3 km (3.3 miles), rim up to 630 m (2,070 ft) above the caldera floor.
  • At least 17 explosive eruptions from the caldera in the last 5,000 years – Sete Cidades is considered the most active volcanic system of the Azores over that period.
  • 1439: last eruption inside the caldera, the Caldeira Seca pumice cone forms (date per Azores Geopark; other sources say 'around 1440, uncertain').
  • December 1713: after weeks of earthquakes, hot mud and gases emerge at Pico das Camarinhas – an aborted flank eruption.
  • 1811: a submarine eruption off Ponta da Ferraria creates the island of Sabrina, which a British frigate captain claims for the Crown; it disappears again after months.
  • 1901: visit of King Carlos and Queen Amélia – hence the name Vista do Rei ('the King's view').
  • 1830: rebuilding of the Muro das Nove Janelas aqueduct on the eastern rim, today a stop on the PR4SMI.
  • 15 April 1989 – 26 November 1990: the Monte Palace operates, named Portugal's best hotel in 1990, closed after 18 months; security guard until about 2010, looted since.
  • 11 September 2010: Lagoa das Sete Cidades is voted one of the Seven Natural Wonders of Portugal.
  • 29 August 2024: the Azores government recognizes the renovation and expansion project of Constellation Version, S.A. for the Monte Palace as being of relevant public interest.

By buggy, quad or bikeSete Cidades on your own wheels

The crater-rim road and the forest tracks around the caldera are buggy and quad territory. If you would rather pedal: e-bikes are available in the village, with a GPS track.

Outdated onlineWhat other sites get wrong

“Vista do Rei is at 544 meters.”
The regional government's official page gives 656 meters (2,152 ft).
“The Monte Palace is an Instagram spot – just walk in.”
Private property, main entrance walled up, entry prohibited and life-threatening because of open elevator shafts. That people do it anyway does not make it legal.
“The hotel reopens in 2021.”
The investor has never built since 2017. Only on 29 August 2024 was the project recognized as being of public interest; as of 09/2026 construction has not begun.
“PR3 is a loop back to Vista do Rei.”
PR3SMI is one-way: 7.5 km (4.7 miles) downhill into the village. Back to the car means the same way up, or a taxi.
“The bus stops at Vista do Rei.”
Lines 205–208 go to the village. There is no bus stop at the viewpoint.

Quick answersBefore the drive up

Where is the best viewpoint in Sete Cidades?

Vista do Rei is the famous one, Boca do Inferno the better one: from the 'Lagoa do Canário' lay-by on the EN9-1A you walk 15–20 minutes to the rocky spur and see three lakes at once. Both are free.

How long can you park at Vista do Rei?

20 minutes in the small lot right at the viewpoint. For longer – the PR3SMI, say – there is the larger car park at the junction behind it. Both free.

Can you visit Sete Cidades without a car?

Yes, on lines 205–208 from Ponta Delgada in about an hour – but only to the village. From there the PR3SMI climbs two hours to Vista do Rei, or you take a taxi. Without a car, a tour is usually the simpler option.

Is Sete Cidades still active?

Yes, CIVISA monitors Sete Cidades as an active system – the caldera last erupted in 1439, the flanks in 1713 and 1811. On 22 September 2026 there is no alert (V0), there are no fumaroles in the caldera and no restrictions.

What do you do if it is foggy at the top?

Go to the village or the lake shore first; the sun is often out there while the rim sits in cloud. Then drive up again later – the cloud comes and goes. The 'Sete Cidades Cumeeiras' webcam shows you beforehand what it looks like.

Is Sete Cidades open right now, and is the volcano dangerous?

Yes, everything is open, there are no closures. On 22 September 2026 CIVISA lists Sete Cidades at the lowest level (no alert, V0). The only hazards are drop-offs on the crater rim, slippery descents and the hotel ruin.

Does Sete Cidades charge admission?

No. Viewpoints, roads, trails, car parks and the lake shore are free. The only things to spend money on are kayaks, SUPs or bikes in the village (about €15 per two-seat kayak per hour) and tours.

Do you need a guide or a tour?

No. With a rental car you reach both viewpoints in 30 minutes from Ponta Delgada, and the PR3SMI and PR4SMI trails are marked in red and yellow. Tours only pay off if you have no car or want to see several sights on the island in one day.

How do you get from Ponta Delgada to Sete Cidades?

By car about 20 km (12 miles) on the ER9-2ª to Vista do Rei, 25–30 minutes. The bus (Auto Viação Micaelense, lines 205–208) takes about an hour and goes to the village, not to the viewpoint.

Can you go into the Monte Palace hotel ruin?

No. The building is private property, the entrance has been walled up, entry is prohibited and life-threatening because of open elevator shafts and missing railings. The best view of the ruin is from Vista do Rei anyway.

How do you get to Boca do Inferno?

From Vista do Rei about 4 km (2.5 miles) along the crater-rim road (EN9-1A) to the 'Lagoa do Canário / Boca do Inferno' lay-by, then 15–20 minutes on foot through the forest to the rocky spur. Free; note the sign with the gate hours at the forest access road.

How long do the hikes take?

PR3SMI from Vista do Rei into the village: 7.5 km (4.7 miles), 2 hours, easy. PR4SMI from Mata do Canário along the crater rim into the village: 11.7 km (7.3 miles), 3 hours, moderate. Both one-way, both with a steep, slippery final descent.

Can you kayak or swim in the lakes?

Kayaks, canoes and SUPs are rented on the lake shore in the village in season (Futurismo €15 per two-seat kayak per hour, from age 5, life vest mandatory). The shore in the village is flat; no official swimming ban was found, but there is no lifeguard.

Is Sete Cidades suitable for children?

Yes: views with no effort, a picnic area and flat shore in the village, kayaks from age 5. Hold children by the hand on the crater rim and at Boca do Inferno.

When can you see the lakes without fog?

Most likely early in the morning before 10 am; the caldera often clouds over during the morning. April to June are considered the most reliable months. Check the 'Sete Cidades Cumeeiras' webcam on SpotAzores first.

What should you wear?

Layers and a rain jacket, even in summer – it is windy and noticeably cooler on top than in Ponta Delgada. Sturdy shoes for the trails, sun protection for the crater rim, since there is no shade.
