Not very challenging walk, but ~8km roundtrip from the bus/parking lot. Not much elevation difference. Lots of birds at the far end of the trip, and hut (which is apparently closed off season? At least, it was on a December Wednesday I visited it).
After that, if feeling up to it, Caracal is ~4km away along the road, and then there's old donkey trail from Caracal to Machico (~8km more). I did the whole thing, GPS recommended for the donkey trail (I lost the trail two, three times).
