Arabuko-Sokoke Forest is the largest fragment of intact coastal forest remaining in East Africa, covering around 420 square kilometres just a few kilometres from Watamu. It is a biodiversity stronghold: globally threatened mammals including the golden-rumped elephant shrew and the Ader's duiker live here, along with dozens of rare and endemic bird species.
Walking and cycling trails wind through the forest from the main gate near Gede. Guided walks in the early morning are the best way to spot the endemic birds. The forest is generally easy to navigate and the guides are excellent. It makes a strong half-day complement to a visit to the Gede Ruins next door.
