Start your journey in Tremês. Upon reaching the village of Barreirinhas, turn right towards the Algar
do Pena Caves Underground Interpretation Center. Hidden within the deep karst landscape of the Serras de Aire e
Candeeiros Natural Park, you will find this remarkable masterpiece of nature. Approximately 40 meters below the
surface, the view opens into a spectacle of light and forms, featuring a vast and unusual array of speleothems (cave
formations)
Return to the road heading towards Valverde and take the EN 362 highway to Alcanede, your next stop. Along the way, marvel at the rugged yet productive scenery, shaped by human willpower. As you approach the town, you will see its lofty castle standing tall—an open invitation for a visit. Likely of Moorish origin and rebuilt after the 1531 earthquake, the main gate features a curious heraldic sculpture depicting three castles and an eagle within a scrolled frame. Once inside, climb the walls and let your soul expand as you take in the horizon, dotted with mountain villages. You are in for a surprise.
Finally, take the EN 362 back to Tremês, where your itinerary concludes. Take the opportunity to explore this charming village further on foot.

Route Description: Starting from Santarém, take the EN3 towards Cartaxo/Lisbon. Just after the Asseca bridge, turn
right and pass through Póvoa da Isenta and Atalaia. Stop at the entrance of Almoster to visit its Convent. This 13thcentury Gothic building reveals a magnificent interior adorned with 17th-century polychrome tiles. The woodcarvings,
paintings, frescoes, side altars, and sculptures found here are truly remarkable.
Leave Santarém via the EN 362 towards Romeira. Once there, turn right onto the road that leads to Azóia de Baixo.
Just ahead of this charming village, prepare for your first mandatory stop: Quinta de Vale de Lobos. This was the
residence of the historian, politician, and novelist Alexandre Herculano, whose legacy is also tied to the production of
the first virgin olive oil in Portugal. Here, you can enjoy a tasting of this local product and take a guided tour through
the olive groves—moments that confirm the historical importance of this estate, beautifully preserved by its current
owners.
