Tips from the Community
The area of the springs, on the Ota River, was once a leisure area for the local population, including the local bathing area in the summer. This site remained natural for a long time after the EPAL was installed, but at a certain point, the intensification of agriculture with the use of chemical fertilizers and pesticides, intensive livestock farming, and urban sewage made the flow from upstream a polluting threat to EPAL's water intakes, and EPAL paved several dozen meters of the river course near the site where it is installed with reinforced concrete.

The Ota River has its source in the Montejunto mountain range. It flows through the Ota area and empties into the Alenquer River, which in turn meets the Tagus River near Vila Nova da Rainha. At this point the river is close to the village of the same name, Ota.

I mentioned that on my previous suggestion for this place. There is an alternative to the blackberry vines: a little before you start to find them, turn left to a little footpath that goes between the trees, it is sloping and can be slippery in winter.

This trail was great fun, but unfortunately blackberry vines have joined the ferns near the end and made the passing a bit complicated.

The karst landscape of Montejunto constitutes the extreme southwest of the Estremenho Limestone Massif. Deep valleys, lakes, gravel pits and lapiás are some of the formations found here, testimonies of various geological eras. Water has been the protagonist in erosion phenomena over time. Several deposits of gravel pits result from the cracking of the outcrops caused by the expansion of the water which, when freezing, breaks the rock into small parts.

Small trail that goes through the stunning vegetation that surrounds it. At the end, the trail seems to have no way out, carefully pass between the ferns that are probably taller than you and that block visibility. Visit and respect and Nature.

Interesting trail, which passes right next to several windmills, some of them recovered. The trail has small sections with very steep slopes, so the easiest way to do it is downhill, that is, towards Serra de Montejunto, Vila Verde dos Francos. For those who are in Vila Verde dos Francos, it is preferable to go up the Estrada de Montejunto (N-115) to the sign that says Caminho dos Moinhos, and then turn right.
