Book Now to Discover Portimão’s Neanderthal Past 2026 in Faro, Algarve

Discover the Neanderthal past of the Algarve with a special open day at Gruta da Companheira near Portimão, guided by the Portimão Museum team and ideal for history lovers, curious travellers and expats wanting to understand the region’s deep past.

What is “Book now to discover Portimão’s Neanderthal past”?

This special event is an open day organised by the Portimão Museum at Gruta da Companheira, an important prehistoric site close to Portimão in the western Algarve. Archaeologists have uncovered evidence of Neanderthal occupation here dating back more than 45,000 years, making it one of the key locations for understanding early human history in southern Portugal.

During the visit, you will not enter the cave itself, but you will explore the surrounding excavation area and learn about the discoveries made so far. The focus is on explaining the archaeological work, the tools and methods used, and what the finds reveal about Neanderthal communities in the Algarve.

Why visitors and expats will enjoy this event

For many tourists and foreign residents, this is a rare chance to go beyond beaches and restaurants and connect with the Algarve’s deep-time story. Instead of a museum display, you see an active dig site and hear directly about how archaeologists interpret the evidence.

Because places are limited to 20 people per open day, the experience feels personal and relaxed, with time to ask questions. It is a great option if you are based in Portimão, Alvor or nearby and looking for more cultural things to do in the Algarve in autumn.

What to expect at the Gruta da Companheira open day

Gruta da Companheira is only the second cave in the Algarve where materials linked to Neanderthal communities have been found. The cave itself is made up of two small horizontal chambers connected by several passages, extending roughly 10 metres, with excavations reaching more than four metres deep near the original entrance.

On the open day you can expect:

• An introduction to the history of the site and how it was discovered during construction of Portimão’s wastewater treatment plant in 2016.
• Explanations of the excavation area around the cave entrance and how archaeologists work layer by layer.
• Information about the stone tools attributed to Neanderthals and what they tell us about technology and daily life.
• Details about the animal remains found, including deer, horses, aurochs (extinct wild cattle) and turtles, and what this reveals about the environment and hunting.

The atmosphere is educational but accessible, suitable for adults and older children or teenagers who are genuinely interested in prehistory and archaeology.

Practical information

Dates and opening times

The event runs as a special open day on 17 October 2026, with participants asked to meet at 10am in the car park of the Companheira wastewater treatment plant (ETAR da Companheira), near Portimão.

There is also a second open day on 24 October with a separate registration form and deadline, but the focus here is on the 17 October session.

Registration and group size

Each open day is limited to 20 participants, and advance registration is required via an online form. For the 17 October visit, registrations must be submitted by 14 October.

Because places are so limited, it is wise to book as early as possible if you are planning your Algarve trip around this date.

Tickets and prices

The event information confirms that advance registration is required but does not state any ticket price or whether entry is free. Ticket prices or any participation fee have not been announced in the available details.

If cost is important for your planning, it is best to complete the registration form and wait for confirmation, or check directly with the Portimão Museum for the latest information before you go.

What to wear and bring

Comfortable clothing and suitable footwear are recommended, as you will be outdoors at an excavation area rather than inside a museum. Closed shoes or trainers are more appropriate than sandals.

It is sensible to bring:

• Water and sun protection, especially if the weather is warm and sunny.
• A light jacket in case of wind or cooler conditions.
• A small notebook or camera if you like to record what you learn (respecting any guidance from the organisers).

How to get there

Gruta da Companheira is located near Portimão in the western Algarve, with the meeting point set at the car park of the Companheira wastewater treatment plant (ETAR da Companheira). This is a short drive from central Portimão and easily reached from nearby resorts such as Alvor.

The simplest way to reach the meeting point is by car, especially if you are staying elsewhere in the Algarve. If you are flying into Faro and planning to explore several sites and events, it can be convenient to compare car hire options at Faro Airport so you have flexibility for day trips like this.

Parking is expected to be at or near the wastewater treatment plant car park, as this is the designated meeting point, but you should follow any instructions provided in your registration confirmation.

Tips for making the most of your visit

• Arrive a little before 10am so you have time to park, find the group and settle in.
• Read a short introduction to Neanderthals or prehistoric Iberia beforehand so you can get more from the explanations on site.
• Prepare a few questions for the archaeologists or guides – they are usually happy to share their expertise.
• Combine the visit with a relaxed afternoon in Portimão or a coastal walk to balance culture with scenery.

Plan the rest of your day

After the morning at Gruta da Companheira, you are well placed to enjoy the rest of the day around Portimão and the western Algarve. You could explore more cultural things to do in the Algarve or head to the coast for a change of pace.

If you are keen to see the region from the water as well as underground, this area is also a great base for exploring some of the best Algarve boat trips along the central-west coast.

Where to stay nearby

Portimão is the most convenient base for this event, with a wide range of accommodation and easy road access to the Companheira area. Alvor, just along the coast, is another good option if you prefer a slightly smaller resort feel while still being within a short drive of the meeting point.

Staying in either Portimão or Alvor also makes it easy to combine the open day with beach time, coastal walks and other cultural visits in the western Algarve.
