If there’s one place in the Azores where you can feel the earth is alive, it’s Furnas. Visiting Furnas in São Miguel means discovering a volcanic valley with steaming fumaroles, hot thermal pools, centuries-old botanical gardens and one of the most unique dishes in Portuguese cuisine: stew cooked by the heat of the ground itself.
Furnas isn’t just a tourist stop. It’s where geology, food and wellbeing come together in an experience you won’t find anywhere else in Europe. In this guide, we explain everything you need to know to visit Furnas in São Miguel: what to see, how much it costs, how much time to set aside and how to plan your day.
The Furnas Fumaroles: the island’s volcanic heart
The fumaroles are the first reason to visit Furnas in São Miguel. They’re steam vents, hot springs and volcanic mud bubbling at the surface, with temperatures ranging from 66°C to 93°C. The sulphur smell is strong and unmistakable, and the steam rising from the ground creates a landscape that feels like another planet.
There are two main fumarole areas: one in the centre of the village (next to Terra Nostra Park) and one by Lagoa das Furnas, where the famous stew is cooked. Both are open-air and easy to visit.
The Lagoa das Furnas area has a paid entry of €3 per person (free for residents) and parking at €3 per vehicle. It’s the more interesting of the two, because this is where you can see the pots buried in the ground, slowly cooking with volcanic heat.
Best time to go: between 12:00 and 12:30, when restaurant staff dig up the stew pots. It’s a unique, very photogenic moment.
Furnas Stew: volcanic cuisine
Furnas stew is a traditional Azorean dish cooked exclusively with geothermal heat. A pot with meats (pork, beef, chicken, chouriço, blood sausage), potatoes, cabbage, taro and other vegetables is placed in a hole in the volcanic ground, covered with earth and left to cook for about 5 to 6 hours.
No water is added. The ingredients release their natural juices as they cook, and the steady heat from the ground does the rest. The result is a deep, concentrated flavour you can’t replicate on a regular stove. This dish alone is a reason to visit Furnas in São Miguel.
Several restaurants serve the stew daily, but booking ahead is essential, especially in high season. The large pots are prepared early in the morning and there’s a limited number each day.
Where to eat Furnas stew
| Restaurant | Location | Average price |
|---|---|---|
| Tony’s | Next to the Church of Our Lady of Joy, Furnas centre | €15 to €20/person |
| Já Se Sabe | Rua Jacinto Botelho, Furnas | €15 to €20/person |
| Caldeiras & Vulcões | Next to the Lagoa das Furnas fumaroles | €18 to €25/person |
Tip: Book at least the day before. In high season (June to September), book several days in advance.
Poça da Dona Beija: thermal baths in the middle of nature
Poça da Dona Beija is the most popular thermal complex in Furnas and one of the most visited spots in São Miguel. There are five outdoor pools of iron-rich thermal water, with temperatures between 25°C and 39°C, surrounded by tropical vegetation. The atmosphere—especially at night with the lights on—is outstanding.
The water is naturally rich in iron and minerals, which gives it a brownish colour. It’s safe and good for the skin, but it’s best to bring a dark swimsuit, as the minerals can stain light fabrics.
Visits are limited to a maximum of 1 hour and 30 minutes. We recommend buying your ticket online in advance, as capacity is limited and it often sells out during the summer months.

Terra Nostra Park: centuries-old gardens and a thermal pool
Terra Nostra Park is another must-do when visiting Furnas in São Miguel, but it’s very different from Poça da Dona Beija. Founded in 1775, it’s a botanical garden of over 12 hectares, home to one of the world’s largest collections of camellias and cycads, as well as hundreds of tropical and subtropical plant species.
At the centre of the park is the famous thermal pool, a large basin of volcanic water at around 40°C, yellow-orange in colour due to its high iron content. It’s a completely different experience from regular pools: swimming in warm water surrounded by centuries-old trees is something you won’t forget.
The water can stain clothes and temporarily tint the skin (the orange tone comes off with a good shower), so bring a dark towel and a swimsuit you don’t mind sacrificing.
Practical information: Terra Nostra Park

Tip: Arrive at opening time (11:00) to enjoy the pool with fewer people. From 13:00 onwards, especially in summer, it gets significantly busier.
Poça da Dona Beija or Terra Nostra? Quick comparison
Anyone visiting Furnas in São Miguel always asks which of the two thermal experiences to choose. Here’s a quick comparison:
| Poça da Dona Beija | Terra Nostra Park | |
|---|---|---|
| Type | 5 outdoor pools | 1 large pool + botanical gardens |
| Temperature | 25°C to 39°C | ~40°C |
| Opening hours | 8:30 to 23:00 | 11:00 to 16:30 |
| Night bathing | Yes (from 18:00) | No |
| Price | €12 to €16 | €17 |
| Duration | 1h30 (limited) | No limit (within opening hours) |
| Best for | Intimate atmosphere, evening | Gardens, full experience |
If you have time, visit both. If you have to choose one, Poça da Dona Beija is more flexible for opening hours, and Terra Nostra is more impressive as a complete experience.
How to plan your day in Furnas
Furnas is in the eastern interior of São Miguel, about a 40-minute drive from Ponta Delgada. There’s no practical public transport to the valley, so a car is the most efficient way to get there and move between the different points of interest.
A full day visiting Furnas in São Miguel can follow this sequence:
- Morning: Arrive in Furnas and visit the Lagoa das Furnas fumaroles (take the chance to see the stew pots being dug up around 12:00).
- Lunch: Furnas stew at one of the local restaurants (book ahead).
- Early afternoon: Terra Nostra Park, with a dip in the thermal pool and a walk through the botanical gardens.
- Late afternoon or evening: Poça da Dona Beija, to end the day with a relaxing thermal bath.
Checklist for your visit
- Time needed: Set aside the whole day. Furnas is best enjoyed at a relaxed pace.
- Swimsuit: Bring at least two (one for Terra Nostra, another for Poça da Dona Beija), preferably dark
- Dark towel: Thermal water stains light fabrics
- Comfortable shoes: For walking around the fumaroles and the park
- Bookings: Stew (restaurant) and Poça da Dona Beija (online tickets). Without booking, you may not get in
- Jacket: The Furnas valley can be cool and humid, even when the rest of the island is sunny
