Some of the walks in the islands provide challenges which require previous hill walking experience, a higher than average level of fitness and proper walking footwear. For some walks guides are a necessity and can be arranged and paid for locally where as others are well signposted and there is no need for a guide.
On Santo Antão, the classic walks are up and down the ribeiras where the views of the craggy peeks and deep gorges are amazing.
On Fogo, the most challenging is the ascent of the Pico in the crater, the top of which is 2829m. There are also many walks from the top of the crater down its sides.
