Sesimbra is a municipality located right near the mouth of the Sado River, and its natural harbour, hence why fishing is the main activity in the area, be it professionally or for sport. Sesimbra is a popular diving location close to Lisbon and the most famous dive site is the wreck of the River Gurara, a Nigerian cargo ship, that sunk in 1989. The other main source of revenue in Sesimbra is tourism, which can be explained by its beautiful beaches, the Arrábida National Park, fish and seafood restaurants, as well as the nightlife.
On a mountain top right above the village lays the Moorish castle, taken by the portuguese during the Reconquista in the year 1165. On the battlements you can enjoy an amazing panorama over Sesimbra and its harbour as well as the surrounding countryside and parts of Serra da Arrábida, (a mountain range which extends from Setúbal to Sesimbra). Near the castle, in the early 13th century, a small Romanesque chapel was built by king Sancho I. Where the chapel once stood, another church was built in 1721 and throughout the years it was abandoned. However, it was restored very recently and you can now appreciate its walls inlaid with azulejos (painted and decorated ceramic wall tiles).
How to get there:
Go to the Praça de Espanha Bus Station and find the TST (bus company) stop for the 207 – Lisboa (Pça de Espanha) – Sesimbra (via AE). A one way ticket would set you back around 5€ per person and the trip takes about 45 minutes. Schedule (be aware that the frequency of transportation on the weekend is very low, we advise you to travel there during the week).
What to do there:
If you travel there early in the morning you could appreciate the view from the Moorish castle and visit the church. Perhaps if you’re more adventurous you could hike in the Arrábida National Park. Lunch in one of the dozens of seafood and fish restaurants in the village and after a walk along the beach maybe get your feet wet.
If you have diving as a hobby or maybe you want to try it out you can do so in here. The waters in Sesimbra are crystal clear but a bit chilly, if you are used to Caribbean Waters. You will need a 5 mm suit to protect you. Water temperature is the same year round. There are a few reputable diving school also doing tours and renting equipment. Some even lead deep water dives in Sesimbra waters.
Have I mentioned the seafood? It’s worth to mention it again, as every restaurant is supplied with fresh caught seafood and fish from the local fisherman and it is delicious. So if you like food that comes from the ocean you’ll definitely be in the right place. And I’ll share a little secret with you, my number one seafood restaurant in Portugal “O Rodinhas”. You can take my word for it, or even the many reviews, but you should really try out for yourself. Be aware though, arrive early or you’re going to have to wait a while for a table.
As always, be mindful of the transportation schedule and don’t get yourself trapped there without a way to get back (unless you want to pay 60€ for a cab). Remember to just take in as much as you can and enjoy to the fullest!
