The route starts on the tarmacked road, next to the sign for the dam and the “Anta da Masmorra” megaliths. Follow the sign and start your adventure, seeking out the mysteries hidden within the Serra do Caldeirão.
You’ll cross the Ribeirinha stream. Keep walking along the main track, following the "Grande Rota" (Long Distance Path) signs. Follow this path until you get to the information board about “Anta da Masmorra”, which should be on your right-hand side. Ignore the path that veers off to the right. Turn down a narrow trail to your right, towards the board, and keep going straight until you reach the megalith. Follow the same trail until you reach the main path and then turn right, towards the windmills. Keep going.
Pay close attention here: Take the first left after the second windmill and start heading downhill. Ignore the two paths to the left and keep going straight ahead. You’ll then come across a dam to your right. This is the perfect place for a rest.
Head downhill, where you’ll find yourself back at the Ribeirinha stream. As soon as you’re ready to leave, turn right.
When you get to the tarmacked road, turn left and you’ll find yourself back at the starting point.
