(S/E) Head north towards Tarrafal and follow the paved road to Monte Trigo. There are no intersections, so it is impossible to take a wrong turn.
As this trail is constantly overlooking the mountainside, the views are varied and change constantly as you wind your way along! Santo Antão is a volcanic island, so you will be surrounded by a mineral landscape with very little vegetation. The trail winds around the hills, and you may sometimes feel like you are no longer going in the right direction!
Once you reach Monte Trigo, return by the same route or by boat.
For the return journey, it is advisable, and even recommended, to take a local fishing boat. To do this, you will need to hire the services of a fisherman in Tarrafal before setting off on your hike (rates are very affordable) and agree on a time with him.If you choose this option, you will need to choose a day when the sea is calm, but this return trip will allow you to follow the path as it winds its way down the mountainside in front of you!
You may even be lucky enough to see whales.
