Natural Landmarks in Indonesia

Indonesia, the world’s largest archipelago, is a country of incredible geographical diversity. Located in Southeast Asia, Indonesia is comprised of over 17,000 islands, stretching across both the Indian and Pacific Oceans. These islands are dispersed across the equator, covering a total area of around 1.9 million square kilometers. The country is part of the Pacific “Ring of Fire,” an area with high seismic and volcanic activity, which has shaped Indonesia’s rugged landscape. This volcanic activity has created dramatic mountains, fertile soils, and vibrant ecosystems. Indonesia’s geography is characterized by diverse landforms that include tropical rainforests, active volcanoes, expansive beaches, coral reefs, savannas, and highland plateaus. The country is home to both some of the world’s most pristine wilderness areas and rapidly growing urban regions. Its climate is predominantly tropical, with both wet and dry seasons shaping the natural environment.
