Malaysia has plenty of nature attractions to satisfy even the most discerning of adventure seekers. More than 50 per cent of its land mass is still under forest cover. Eco-tourism has become a major enterprise in the last decade and Malaysia's natural attractions have been carefully developed. Malaysia contains one of the oldest rain forests in the region and several parks to ensure long-term conservation of the rich biodiversity of plant, insect and animal life. These rain forests are one of the last bastions of the world's rarest plants and animals. Several eco-systems exist in the Malaysian forests, there are wetlands, desert scrub and limestone vegetation, amongst many others to check out.
