Up at 2,000 metres, the air is much cooler than down at the coast. Most days, soft white clouds drift in low and wrap around the trees. The moss soaks up the moisture from the clouds and grows thicker and thicker, until the whole forest looks like it's been knitted from green wool.
The trees here are short, twisty and bent over, very different from the tall straight trees in the lowland rainforest. Cold wind and clouds keep them small. Many are draped in long, dangling lichens that look like green beards. The whole place feels a bit like a fairy-tale forest where you might meet a hobbit.
Tiny meat-eating plants live in the Mossy Forest. The most famous is the pitcher plant - it has a long jug-shaped 'cup' that fills with rainwater and a slippery sweet edge. Small insects come for the sweet smell, slip in, and the plant slowly digests them. Some pitcher plants in Borneo are so big they could fit a mouse.
Cameron Highlands is also Malaysia's main place for growing tea. As you drive up to the Mossy Forest you pass huge green tea plantations clinging to the hillsides like a giant green quilt. The Cameron Highlands is so cool that British tea growers planted tea here almost 100 years ago, and tea has been grown ever since.
