Sumatra - The great island of Sumatra, the third largest in the archipelago and fifth largest in the world (roughly the size of California or Sweden), is Indonesia’s most important territory. In just about every way, strategically, economically and politically, Sumatra has always formed a pivotal "backbone" for the nation. With its grass huts, lake tribes, wildlife reserves, steamy jungles, swampy lowlands, swift clear rivers, spectacular waterfalls, crater lakes, and immense forests full of tropical 30-m-high tress, Sumatra has become the third most popular tourist destination in Indonesia. Called the “Isle of Hope” or “Isle of Gold”, this island’s natural wealth is fabulous. Sumatra is like the Africa of SE Asia.
