Kalimantan The Indonesian province of Kalimantan occupies the greater part of the exotic island of Borneo, where the world's most dense and remote rainforests can be found. The island is famous for its rich concentration of wildlife, and it is equally notorious for its legendary headhunters. Indonesia's second largest province, Kalimantan has become a source of substantial natural wealth for the country. Its extensive oil reserves are now a key part of Indonesia's economy, and diamonds, rare woods, rattan, and resin are also harvested here.
There are parts of Kalimantan that to this day remain unexplored. Eighty percent of Central Kalimantan (the largest sub-region) is thick jungle that often clings to treacherous mountain slopes, hiding valleys that remain utterly inaccessible. Although only the most hardcore and experienced adventurers should consider a foray into these regions, Kalimantan has plenty of less formidable forests open to visitors.
Kalimantan is also home to one of Indonesia's most interesting indigenous cultures--the Dyak. Although they no longer practice headhunting, the Dyak continue to live much as they have for the last millenium, occupying enormous communal longhouses which serve as the residence for large family groups. An ideal way to tour Kalimantan is by riverboat on the Mahakam River, where one can also spot the world's only species of freshwater dolphin. Orang-utan live in the surrounding jungles, and special tours for the purpose of viewing the animals up close are available.
Komodo National Park
The main attraction of this park is the legendary Komodo Dragon, a gigantic reptile found nowhere else. The oldest, largest, and one of the rarest reptiles, the Komodo is a gigantic Monitor lizard that grows to lengths of more than three meters. It scavenges and hunts, using its powerful club of a tail to tackle large prey.
The island of Komodo, along with those surrounding it, is dry and barren, with rainfall occurring only between November and March. It lies about 500 km east of Bali, a location that places it between the Asian and Australian bio-geographical zones and makes the island an interesting crossroads for species. Birds from both zones can be found on the island, such as the Noisy Friar Birds of Australia and the Monarch Flycatchers of Asia.
Bromo-Tengger National Park

Long before there was a nation called Indonesia, there was Bromo-Tengger. This mystic, volcanic region was set aside by Hindus as a sacred place, and to this day thousands make a yearly pilgrimage to the park to honor Mount Semeru, which they consider to be a god.
The landscape of Bromo-Tengger is indeed heavenly. The park is situated around a group of forest encrusted volcanoes that rise up thousands of feet like gigantic, terrestrial limpets. At 3,676 meters, Semeru is Java's highest mountain, and it is still active, erupting once every eight minutes. Though Semeru is the highest mountain, no less astounding is Bromo.
Mount Bromo rests in what is known as the sand sea, a vast, empty expanse of sand 10 kilometers wide that is surrounded by interior slopes of another volcano that became extinct long ago. Bromo is also active, but visitors can trek to the mountain on foot or horseback and climb to the edge of its caldera and experience the spacial wonder of the sand sea below.
