Leaving the beach resorts behind, Malaysia's wild jungles, volcanic peaks and fabulous national parks make this country an adventure destination to get anyone's blood pumping. Opportunities for hiking, jungle trekking, rock-climbing and wildlife expeditions abound. Try tracking elephants in Taman Negara, chasing orang-utans near Sabah and Sarawak on Borneo or searching out Malaysia's very own legendary Bigfoot in Endau-Rompin National Park. Check out the world-class dive spots in Tun Sakaran Marine Park or go off the beaten track to attempt the Headhunter's Trail, explore the world's largest cave system and trek through the mysterious jungles and bizarre Pinnacles of Sarawak. If that's not enough to excite you, take note that the highest peak in Southeast Asia lies within the borders of East Malaysia. The stunning views from Mt. Kinabalu's summit make this two- to three-day trek worth the early-morning climb.
