Malaysia's territory covers peninsular Malaysia -- bordering Thailand in the north just across from Singapore in the south -- and two states on the island of Borneo, Sabah and Sarawak, approximately 240km (150 miles) east across the South China Sea. All 13 of its states total 329,749 sq. km (127,316 sq. miles) of land. Of this area Peninsular Malaysia makes up about 132,149 sq. km (51,023 sq. miles) and contains 11 of Malaysia's 13 states: Kedah, Perlis, Penang, and Perak are in the northwest; Kelantan and Terengganu are in the northeast; Selangor, Negeri Sembilan, and Melaka are about midway down the peninsula on the western side; Pahang, along the east coast, sprawls inward to cover most of the central area (which is mostly forest preserve); and Johor covers the entire southern tip from east to west, with two vehicular causeways linking it to Singapore, just over the Strait of Johor. Kuala Lumpur, the nation's capital, appears on a map to be located in the center of the state of Selangor, but it is actually a federal district similar to Washington, D.C., in the United States.
On Borneo, Sarawak and Sabah share the landmass with Indonesia's Kalimantan. Also sharing the island, in a tiny nook on the Sarawak coast, is the tiny oil-rich Sultanate of Brunei Darussalam.
Back on the peninsula, the major cities can be found closer to the coastline, many having built on old trade or mining settlements, usually near one of Malaysia's many rivers.
The Lay of the Land -- Tropical evergreen forests, estimated to be some of the oldest in the world, cover more than 70% of Malaysia. The country's diverse terrain allows for a range of forest types, such as montane forests, sparsely wooded tangles at higher elevations; lowland forests, the dense tropical jungle type; mangrove forests along the waters' edge; and peat swamp forests along the waterways. On the peninsula, three national forests -- Taman Negara (or "National Forest") and Kenong Rimba Park, both inland, and Endau Rompin National Park, located toward the southern end of the peninsula -- are the most convenient to get to, especially Taman Negara, a short trip from KL, which has well-developed facilities and regular guided nature tours. Sabah and Sarawak step up the adventure quotient with countless rainforests, peculiar wildlife, and fascinating indigenous cultures.
Malaysia is surrounded by the South China Sea on the east coast and the Strait of Malacca on the west, and the waters off the peninsula vary in terms of sea life (and beach life). The waters off the east coast house a living coral reef, good waters, and gorgeous tropical beaches, while more southerly parts host beach resort areas. By way of contrast, the surf in southern portions of the Strait of Malacca is choppy and cloudy from shipping traffic -- hardly ideal for diving or for the perfect Bali Hai vacation. But once you get as far north as Penang, the waters become beautiful again. Meanwhile, the sea coast of Sabah and Sarawak counts numerous resort areas that are ideal for beach vacationing and scuba diving.
