The western half of Malaysia doesn't have mountains as much as it has rolling hills. The British occupiers in the late 19th century sought refuge from the lowlands' stifling humidity in these hills. Realizing the amazing fertility of the highlands in Pahang, some British entrepreneurs set up tea plantations here, which still serve as the Cameron Highlands' main attraction.
At an altitude of 6,000 feet above sea level, the Cameron Highlands now serve two functions: a site for some of Malaysia's biggest tea plantations, and a genteel highlands resort renowned for its cooler climes (compared to the rest of Malaysia), favored in particular by honeymooners.
Visitors to the Cameron Highlands can enjoy a number of activities well-suited to the place and climate, including (but not limited to) picnics, tours of the area's many tea plantations, strawberry-picking, and trekking.
