Castelo de Alcoutim is a 14th-century medieval castle and archaeology museum in the village of Alcoutim, in the far north-east of the Algarve, Portugal, overlooking the Guadiana River and the Spanish village of Sanlúcar de Guadiana on the opposite bank. This guide covers opening hours, ticket prices, getting there, parking, accessibility, what to see inside, and practical tips for first-time visitors.
Last updated: April 2026. Several guides — including some still widely cited in 2025 — show a daily lunchtime closure at the castle. The official museum website confirms the castle closes for lunch only on Sundays and public holidays, not on weekdays or Saturdays. On those days, it is open continuously from opening to closing time.

One ticket covers both Castelo de Alcoutim and the River Museum (Museu do Rio), located in the village centre. This combined entry is valid for one week from purchase, making it practical to visit the two sites on different days of the same trip. The week’s validity does not apply to group tickets.
Several additional sites in the Alcoutim municipality are free to enter, including the Religious Art Museum, the Primary School museum, the Blacksmith’s House, the Dr. João Dias Museum, the Lavajo Menhirs, and the Montinho das Laranjeiras Roman ruins. The Old Castle of Alcoutim (a separate, older fortification 1 km north of the village) is also freely accessible.

How to get to Castelo de Alcoutim
Alcoutim is a remote village with very limited public transport connections. A car is the practical means of transport for most visitors.
By car: The main approach is via the N122 road, which follows the eastern bank of the Guadiana River northward from Vila Real de Santo António. The drive from Vila Real takes approximately 55 minutes. From Tavira, the journey is around 55 minutes via the IP1/A22 and N122. From Faro, allow approximately 1 hour 10 minutes. From Mértola in the Alentejo, allow approximately 50 minutes southward on the N122.
By bus: Public transport connections are extremely limited. Vamus Algarve operates bus route 34 between Vila Real de Santo António and Alcoutim, but departures run only on Mondays, Wednesdays, and Fridays, with a single departure from Vila Real at approximately 17:10. Return services run on Tuesdays and Thursdays only. This schedule makes a same-day bus return from the Algarve coast effectively impossible. Verify current timetables on the Vamus website before travel.
By ferry from Spain: A pedestrian ferry crosses between Alcoutim and Sanlúcar de Guadiana in Spain. The crossing costs approximately €1 each way and takes a few minutes, though departures depend on the boatman having sufficient passengers. This route connects Alcoutim to the Spanish road network.
Parking at Castelo de Alcoutim
Alcoutim is a small village and parking is not difficult for most of the year. There is informal parking available along the riverfront promenade and in the streets near the village centre. The castle is a short uphill walk from the riverside. During busy summer weekends, spaces along the waterfront can fill; in these cases, street parking a few minutes’ walk away is usually available. There are no parking charges or time limits in normal use.
How long to spend at Castelo de Alcoutim
Allow 45 minutes to 1.5 hours for the castle and its two permanent exhibitions. Visitors who also plan to cross to Spain by ferry and visit the Castillo de San Marcos on the opposite bank should allow an additional hour. Combining the castle with the River Museum and a walk around the village takes most visitors a comfortable half-day.
Accessibility at Castelo de Alcoutim
The castle sits on a hill above the village and is approached via sloped and sometimes uneven paths. The terrain inside the castle itself also includes uneven ground. The castle is unlikely to be fully accessible for visitors with significant mobility difficulties. Persons with a disability or reduced mobility are entitled to free entry. Visitors requiring specific information about access should contact the museum on +351 281 540 545 before visiting.
Inside Castelo de Alcoutim – what to see
The castle’s rectangular stone enclosure with corner towers was built during the reign of King Denis I in the early 14th century, replacing an earlier Moorish fortification. The structure was subsequently reinforced by King João II and King Manuel I during the 15th and 16th centuries. In 1371, the castle was the setting for a peace treaty between King Fernando of Portugal and King Enrique II of Castile, ending the First Fernandine War. The walls and towers are constructed from local schist stone and have been partially restored.
From the castle battlements and keep, views extend directly across the Guadiana River to Sanlúcar de Guadiana and its own hilltop Castillo de San Marcos (restored). On clear days the valley stretches north toward Mértola. The contrast between the two castles facing each other across a narrow river makes for an unusual and distinctive sight.
Inside the castle, the Archaeology Museum houses two permanent exhibitions:
Alcoutim’s Archaeological Heritage traces human occupation of the Alcoutim municipality from the Neolithic period (5,000–3,000 BC) through to the 20th century. The exhibition has been remodelled three times since its opening in 2000 and is designed as a historical journey that directs visitors through a sequence of thematic discoveries rather than a linear chronological display.
Timeless Games occupies the former magazine of the castle and displays a collection of 39 game boards — some complete, others fragmentary — and 18 small playing pieces, all carved in schist. The boards represent six game types from the Islamic period: Alquerque, Tabula, Nine Men’s Morris, Tapatan, and two others. This collection is the largest group of Islamic-era board game boards from a single archaeological site in Portugal, recovered from the Old Castle of Alcoutim by excavations led by Dr Helena Catarino from 1985 onwards.
Practical visitor tips
| Tip |
|---|
| A car is essential for most visitors. Public bus services to Alcoutim run only three days a week and do not permit a same-day return from the coast. |
| The castle is open Monday to Saturday without a lunchtime break. If visiting on a Sunday or public holiday, note that it closes 13:00–14:00 and plan your arrival accordingly. |
| Keep your ticket for the full week. The €2.90 ticket also covers the River Museum in the village centre, with both sites accessible for seven days from purchase. |
| The ferry to Spain costs approximately €1 each way and can involve a short wait for enough passengers to make the crossing. Allow extra time if crossing is part of your plan. |
| Alcoutim village is very small. There are a handful of cafés and restaurants along the riverfront, but limited facilities beyond these. Bring water, particularly in summer. |
