The Ultimate Foodie Experience in the Azores: How to Find the Best Furnas Stew

A practical 2026 guide to the unearthing ritual at Lagoa das Furnas, top restaurant picks, and booking the geothermal cooking experience you cannot improvise.

Each morning in Furnas, cooks lower sealed pots of meat, vegetables, and Azorean sausage into volcanic pits beside Lagoa das Furnas and let the earth do the cooking. By noon, the pots come up. What emerges after six to eight hours of geothermal steaming is Cozido das Furnas, one of the most logistically specific and deeply satisfying meals in Portugal. Planning this meal correctly is the difference between a memorable lunch and a wasted trip.

What exactly is Cozido das Furnas and why does the volcano matter?

Cozido das Furnas is a regional variation of the traditional Portuguese cozido à portuguesa, a slow-cooked stew of beef, pork, chicken, blood sausage (morcela), chouriço, potatoes, yams, cabbage, and carrots. What makes the Furnas version singular is its heat source: the naturally occurring fumaroles and hot springs along the southern shore of Lagoa das Furnas, a caldera lake sitting roughly 350 metres above sea level in the eastern interior of São Miguel Island.

The pots, sealed in burlap and placed inside concrete-lined volcanic pits, cook exclusively through geothermal steam. Ground temperatures at the pit sites reach between 90°C and 100°C, sufficient to break down collagen in the beef over a period of six to eight hours without the aggressive boil of a stovetop. The result is a savory depth that chefs consistently describe as impossible to replicate in a conventional kitchen.

"The volcanic pits are not a gimmick. The mineral-rich steam penetrates the pot differently than surface heat does — the broth absorbs trace sulfur compounds from the soil, and the yams take on a sweetness you do not find anywhere else." — Chef observation widely cited by Azorean culinary guides.

The practice has roots going back at least to the early 20th century, when local families would lower their Sunday meal into the ground before attending Mass and collect it on the return walk. Today, the ritual is both a live culinary heritage event and the logistical backbone of the Furnas restaurant trade.

When and where does the unearthing happen at Furnas Lake?

The levantamento, the formal unearthing of the pots, takes place on the southern shore of Lagoa das Furnas between approximately 11:30 AM and 12:30 PM daily. The exact time shifts slightly depending on how long each restaurant's pots have been in the ground, but arriving at the lake by 11:15 AM gives visitors sufficient time to observe multiple lifts. The site is a short drive or a roughly 20-minute walk from the village of Furnas itself.

Parking is available near the lake, though the access road narrows considerably. Those arriving on guided tours typically benefit from organised transport directly to the shoreline. The volcanic pits are clustered in a visible area close to the water's edge, marked by permanent steam columns rising from the cracked earth. During the lift, workers use hooks and ropes to raise the burlap sacks, which emerge coated in grey volcanic mud and trailing steam.

Witnessing the levantamento is free and open to the public, but the area is compact and fills quickly on peak summer days (June through September). A position near the railing by 11:30 AM is advisable. Photographers note that the steam disperses within minutes of the sacks reaching surface level, so timing matters.

"The smell hits before anything else — not unpleasant, but distinctly mineral, with a warmth that comes from below rather than above. Then the sack rises and the steam follows it like a slow exhale from the ground."

After watching the lift, most visitors drive the short distance back to the village to honour their restaurant reservation. This sequence — lake, lift, lunch — is the standard structure of the Furnas foodie day and the one that produces the most coherent experience.

Which restaurants serve the best Cozido das Furnas in 2026?

The number of pots permitted at the geothermal site is regulated, meaning every restaurant has a fixed daily allocation. This is why walk-in lunch at 1:00 PM is functionally impossible at any serious establishment in 2026. Reservations made 24 to 48 hours in advance are the minimum; during July and August, three to four days ahead is more realistic. Below is a curated breakdown of the leading options by character and approach.

Tony's Restaurant is the historical reference point. Operating near the Furnas Lake pits for several decades, Tony's built its reputation on a straightforward, generous interpretation of the Cozido: large portions, bone-in cuts, abundant morcela, and a broth that carries genuine savory depth. The beef here melts with minimal pressure from the fork after its geothermal cook. The setting is unpretentious, the clientele is a mix of locals and returning visitors, and the value relative to the experience is notable. Book by phone or through the restaurant's website, specifying the number of Cozido portions required.

Terra Nostra Garden Restaurant, inside the Terra Nostra Boutique Hotel and adjacent to the 18th-century thermal gardens of Parque Terra Nostra, offers a more polished environment. The kitchen here also produces a vegetarian Cozido, which is a 2026 must-try for non-meat eaters. The vegetarian version substitutes the animal proteins with local Azorean mushrooms, seaweed harvested from São Miguel's northern coast, and root vegetables cooked in the same geothermal steam. The umami depth achieved through the seaweed and long cook time is genuine, not a compromise. The view of the park's magnolias and the thermal pool adds a specific ambience that Tony's does not provide.

Caldeiras e Vulcões takes a more contemporary presentation approach: smaller plates, cleaner broth served separately, and individual cuts plated rather than served family-style. It suits travellers who want to assess each element of the Cozido analytically. The restaurant is situated within walking distance of the main village thermal springs.

À Terra, the restaurant inside the Octant Furnas hotel, offers the most modern interpretation in 2026. The kitchen applies minimal intervention principles to the geothermal cook, sourcing directly from Azorean producers and presenting the Cozido components with a chef's sensibility around portion size and balance. Bookings are taken through the Octant reservations system and tend to fill within 48 hours during the high season.

When tasting the Cozido, regardless of venue, look for three markers: the texture of the beef, which should separate at the touch of a spoon and carry no resistance; the mineral sweetness of the inhame (Azorean yam), which absorbs the broth and develops a flavour that is neither waxy nor bland; and the smoke character of the morcela, which should be firm-cased and deep without bitterness.

Can you participate in the cooking process yourself?

A 2026 trend in Furnas is the emergence of geothermal cooking workshops that allow travellers to move from observer to participant. Octant Furnas and a number of tour operators including those bookable through platforms like GetYourGuide now facilitate sessions in which small groups help prepare the pot — seasoning the meats, packing the vegetables, sealing the pot — before lowering it into the volcanic pit themselves. The workshop typically begins around 6:00 AM or 7:00 AM, with participants returning to eat the results at lunch, completing the full cycle from soil to table.

These workshops are limited to groups of six to twelve people and book out weeks in advance during the summer season. They represent the most immersive available encounter with Cozido das Furnas as a process rather than simply a product. ToursXplorer lists curated Furnas tours that incorporate the lake visit, the levantamento observation, and the Cozido lunch in a single structured day, which is the most efficient way to manage the logistics without individual coordination.

For travellers who want the geothermal story without the full workshop commitment, several Furnas valley guided tours include a narrated visit to the volcanic pits as part of a broader itinerary covering the hot springs (Caldeiras das Furnas), the thermal gardens of Parque Terra Nostra, and the endemic flora of the lake shoreline, where Myrica faya and hydrangeas line the access paths.

Planning your Furnas stew day: a practical timeline for 2026

The most common mistake travellers make in Furnas is treating the Cozido as a spontaneous lunch stop. It is not. The following timeline is the one ToursXplorer recommends for travellers organising the day independently.

48 to 72 hours before your visit: Make your restaurant reservation, specifying the number of Cozido portions. If you are at Terra Nostra, confirm whether you want the vegetarian version, as it requires separate pit space. For Octant's À Terra, use the hotel reservation system directly.

Morning of the visit: Arrive at the southern shore of Lagoa das Furnas by 10:30 AM. This gives you time to walk the lake perimeter (approximately 3.5 kilometres), visit the chapel of Nossa Senhora das Vitórias at the lake's edge, and settle near the pit area before the levantamento crowd arrives.

11:30 AM to 12:00 PM: Watch the unearthing. Stay for at least two or three lifts to observe the process fully. The steam diminishes quickly, so do not delay for photographs.

12:30 PM to 1:00 PM: Drive the roughly 2 kilometres back to the village of Furnas for your reservation. The meal itself typically runs 90 minutes at a relaxed pace, which is appropriate given the weight of the food.

Afternoon: The Caldeiras das Furnas hot springs in the village centre and the thermal gardens of Parque Terra Nostra (entry fee applies) are the natural post-lunch destinations. The thermal pool inside the park, a rectangular iron-rich basin at approximately 39°C, is a logical place to end the day before the drive back toward Ponta Delgada, which is roughly 40 kilometres to the west.

Is the vegetarian Cozido das Furnas worth ordering in 2026?

The vegetarian Cozido at Terra Nostra Garden Restaurant is the most discussed new item on the Furnas culinary map in 2026, and the interest is justified. The kitchen uses Agaricus bisporus and foraged Azorean mushrooms alongside dried seaweed (primarily Undaria pinnatifida, farmed in the Azores archipelago) to build the umami base that smoked meats traditionally provide. Root vegetables, including inhame, carrots, and local potatoes, complete the pot.

The geothermal cook time for the vegetarian version is slightly shorter at around four to five hours, as the vegetables reach optimal texture before the longer proteins would. The result is a broth with genuine mineral depth and a body that holds without the animal fats. It is not a simulation of the meat version: it is a distinct dish that shares the cooking method and some of the flavour logic while arriving at a different sensory conclusion.

For travellers who eat fish, several Furnas restaurants also offer a fish-based variation using Atlantic mackerel and local wrasse, though this is less standardised than the vegetarian option and should be confirmed at booking.
