VOLCÁN MADERAS

The Maderas volcano (a 4,100-hectare nature reserve) is home to a pretty lagoon in its 1,394-m-high crater; the cloud forest at the summit echoes with the howler monkey's howl, and the fauna is interesting. The trails are not easy and progress is strenuous: allow at least 6 to 7 hours' walking, sometimes more. Bring plenty of water and sturdy walking shoes. The last part of the climb is particularly strenuous. But don't panic, others have done it before you: just breathe and don't take anything lightly.
