(S/E) From the side of the road, where you can easily park (the waterfalls are signposted and there are always cars there), take the path that runs alongside the sugar cane field.
(1) Go straight ahead; at one point, continue on a narrower path, and the descent to the waterfalls begins.
You will arrive at the first viewpoint and the first waterfall. Then cross the river and take the path opposite that leads into the forest.
You will arrive at the third waterfall: beautiful views and the opportunity to swim. Continue along the easily identifiable path through the forest to reach the fourth waterfall.
(2) You can continue on to the other two waterfalls, still following the same path. Otherwise, (choice of route), head back up to the car park by turning right. Be careful, the slope is very steep and you will need to use the branches to help you climb back up, but the path is well marked.
At the top, at the intersection, turn right to join the path along the sugar cane field and return to the car park (S/E).
