Turn right when you leave the car park, and you’ll find Point 1. Keep going, and you’ll cross the stream called Ribeira da Chapa, then turn left at the junction (follow Connection 2 of the Via Algarviana). At the bottom of a gentle downhill section, you’ll reach a junction where you can either go straight on or turn left. Go straight ahead and you’ll find the irrigation channel on your right, channelling water straight from the spring. The sign signalling Point 2 should be easy to find here: "A Nascente" (The Spring).
Make your way back to the junction and turn left this time. You’ll find the spring itself, which can be accessed via some stairs. At the spring, take the right path between Ribeira de Menalva (Menalva Stream) and the irrigation channel. When you reach the ruins of a water mill, follow the path between it and the wall to find a noria on your right. This is where you’ll find Point 3. Keep going along the path, which is walled on both sides, until you reach the main path.
When you reach the main road, turn right, where you’ll find Point 4; this is the path you took at the start of the trail. At the junction, turn right towards the car park, and you’re back to the starting point. Now follow the road you drove along earlier.
Take the second path on the right, where you’ll find a narrow trail going downhill, about 60 metres from the car park. You’ll find Point 5 at the end of the path, as well as a noria. Keep the noria on your right as you follow the path to the left. You should see the stream on your right and a canal on your left. You will have to cross this canal farther on, taking all necessary precautions.
On the other side, you’ll find a sign with Point 6 on it, and yet another noria. Take the path in front of you (alongside the noria wall), and you’ll find yourself at the irrigation channel once again. Keep on, in the same direction.
Farther ahead, the irrigation channel veers right, while you take a path to left that heads uphill. Follow the main trail uphill until you reach the main path, which is walled on one side. Turn left here and keep on the main path until you get back to the starting point.
