The Loulé Salt Mine: a Guided Walk 230 Metres Under the Town

Under the market town of Loulé, 16 km inland from Faro, a company still cuts rock salt out of the ground. It also takes visitors down. You ride a lift cage 230 metres to the working level, put on a helmet and walk about 1.3 km of the mine’s roadways behind a guide, past the machines that do the cutting and chambers left by decades of digging.

It makes a good half day away from the lagoon, and a plan that doesn’t care about the weather: it’s 23 to 24 °C down there all year. The catch is the calendar. Tours run on working days only, Monday to Friday and not on Portuguese public holidays, so a weekend in Faro can’t include it.

What the visit is

The mine is Campina de Cima, run by TechSalt. Rock salt was found under Loulé in the 1950s and work on the two shafts began in 1964. It has been mined ever since, and has run regular public tours since October 2019. Loulé’s tourism office calls it Portugal’s deepest tourist site.

What you see is a working industrial site, not a show cave. The galleries are wide enough for lorries, and some of the formations you walk past are more than 230 million years old. The guide covers how the salt got there, how the digging changed from the early years to today’s machines, and what the salt is for. It has long gone to industry, and the company also sells brine for de-icing roads.

The details that matter before you book:

• The lift is a cage that takes seven people and about three minutes to reach the bottom.
• The whole visit takes about two hours.
• Helmet, torch and a reflective vest are handed out; closed shoes are recommended.
• Children under 6 are not admitted, and 6 to 12-year-olds must be with an adult.
• The mine says it’s not for anyone uneasy in dark or closed spaces.
• Guides speak English and Portuguese on every day it opens, with French and German on some tours.

Booking it

The version on this page is the mine’s own tour, sold through GetYourGuide. It costs from about $28 a person, is rated 4.8 from 1,784 reviews, and can be cancelled free up to 24 hours before. The mine also sells tickets at its desk, and its adult price was €25 when last reported in September 2026, so booking ahead costs about the same and fixes your time for a lift that takes seven at a time.

Recent guests mostly write about the guides. “Our guide was so knowledgeable about the history and story of the mines,” wrote Eva from Ireland in September. Leonie from the UK called it “very interesting & spectacular”.

Getting there from Faro

Loulé is about 16 km from Faro by road. Driving is simplest, and there is a car park for visitors inside the mining park. By bus it takes around 40 minutes. The train is quicker on paper, but Loulé’s station sits about 5 to 6 km outside the town, so you’d still need a taxi at the other end. The listing doesn’t include hotel pickup.

Weekdays only, and the Saturday market

Loulé’s big market day is Saturday. A farmers’ market fills the centre, and a large flea market, the mercado de levante, sets up on the edge of town from about 8 am to 2 pm. The mine is shut that day.

If you want both the mine and a market in one trip, go on a weekday. The Moorish-style municipal market in the centre is open Monday to Saturday from early morning into the early afternoon, with fish, fruit and local produce. Browse it in the morning and take an afternoon tour: English tours start at 9:15, 10:45, 14:15 and 15:45, so 15:45 is the last of the day. Portuguese tours run half an hour later. Check in 10 minutes before.

Is the salt mine worth it?

For most people who’ve done the lagoon and want something different, yes. It’s an unusual thing to do in the Algarve, it’s indoors and steady in temperature, and 1,784 reviews average 4.8.

Who should think twice: anyone who dislikes enclosed spaces, families with a child under 6, and anyone who can only go at the weekend. People who want pretty crystal caves may also be a little surprised. This is a mine with machines in it.

Salt from the sea, salt from the rock

This site is mostly about the Ria Formosa, and the lagoon makes salt too. Its salt pans at Tavira, Olhão and Faro still make sea salt and flor de sal by letting the sun evaporate seawater, and those same shallow pans are where the lagoon’s flamingos feed at high tide. Rock salt is the same idea on a geological clock: seawater that dried out long ago and was buried. A morning on the pans and an afternoon 230 metres under Loulé make an odd but satisfying pair.
