Sayap is a small sub-station of Kinabalu Park on the very wet western slopes of Kinabalu. The area is bisected by numerous narrow valleys and fast flowing streams. This stream is known as the Sungai Kemantis. Sg. Kemantis is a tributary of the Sungai Wariu, which itself is a tributary of the Tempassuk River which flows past Kota Belud and into the sea at Kuala Abai. See the map at the bottom of this article.
The wetter the climate in Borneo the greater the variety of fig species . Sayap is very rich in rare interesting figs. Growing up the tree at the back is the rare root climber Ficus densechini with large leaves and enormous figs the size of a very large orange. In the stream below are two examples of Ficus lepicarpa which grows as a small tree.
