This park has more natural wonders with hundreds of limestone caves on the surface and as many underground, formed by the action of underground streams, probably the largest salt water reserves in the country, all littered with stalactites and stalagmites. About twenty-five species of orchids decorate the landscape of the park that is home to all types of reptiles, birds, mammals and invertebrates.
Santarém is known as the country's bullfighting capital, and surrounding the town are rich pastures grazing bulls and horses. In June there is a huge agricultural fair, when it is the best time to catch a bullfight and horse races. Other bullfighting festivals take place nearby in Vila Franca da Xira, known as "the Pamplona of Portugal," where there's the running of the bulls during the first weeks of July and October.
Everywhere you turn in Obidos is like seeing a picture postcard. This medieval village was a wedding gift King Dinis gave to his bride Isabel in 1282, with whitewashed houses inside the walls of the castle. It remained property of Portugal's queens until the 19th century, and today is one of Europe's best preserved walled villages. Throughout the village you'll see gothic doorways, potted plants and lots of bougainvillea, while the castle is now a pousada. You can walk around its ramparts for the best views and photos. At the end of your sightseeing, try the famous local drink, the ginjinha (cherry liqueur), often served in a chocolate glass. Obidos is also the stage of some of Portugal's most popular festivals. Its chocolate festival, medieval market and "Christmas Village" attract thousands to its cobbled streets throughout the year.
As if it were an amphitheatre, the slopes bordering Foz do Arelho beach, littered with villas and beautiful houses, watch the onslaughts of the sea every day, a sea that has created a unique natural spectacle in the Óbidos saltwater lagoon. Lovers of water sports can take advantage of this momentum to ride the sea, while others come here simply to enjoy the beauty of the Portuguese coastal landscape. If you arrive by car, be sure to take the road that connects Foz do Arelho to São Martinho do Porto, a route with spectacular views of the cliffs.
