Bunaken National Park

Bunaken National Park is a special area in the sea near the north of Sulawesi Island in Indonesia. It is found close to the middle of a very important place called the Coral Triangle. This area gives a home to many kinds of sea creatures, including 390 types of coral, as well as many fish, shells, sea snakes, and even some sea mammals.

The park became a national park in 1991, making it one of the first sea parks in Indonesia. It covers a big space of 890.65 square kilometers, and most of it—about 97%—is underwater. The rest, just 3%, is on land and includes five islands: Bunaken, Manado Tua, Mantehage, Nain, and Siladen. The park also reaches down to part of the coast at Tanjung Kelapa.

Geology

North Sulawesi is a young area, formed between 5 to 24 million years ago. It has a history of strong volcanic activity from 1.5 to 5 million years ago, creating the unique landscape we see today.

Manado Tua, an inactive volcano, stands over 600 meters above sea level and is the highest point in the park. Bunaken Island and Nain Island also have volcanic origins. Mantehage Island is flat and appears to be slowly sinking, while Siladen is a low island made of coral sand. The area lacks a continental shelf, so the sea drops quickly from the coast, reaching depths between 200 and 1,840 meters between the islands.

Flora and fauna

Bunaken National Park is full of colorful sea life. The park has about 390 kinds of coral, including tall coral walls that grow straight up from the sea floor. You can also find seaweeds like Caulerpa and Halimeda, as well as seagrasses such as Thalassia hemprichii.

The park is home to around 2000 types of fish, including the emperor angelfish and the spotted seahorse. Marine mammals, reptiles, mollusks, and many birds also live here. On the land, you can see plants like palms and coconuts, and animals such as the Celebes crested macaque and Timor Deer. The mangrove forests are rich with crabs, lobsters, and many kinds of sea birds.

Human habitation and tourism

The area around Bunaken National Park is home to about 35,000 people living in 22 villages. Many of these people work as fishermen or grow crops like sweet potato, banana, and seaweed. Others help tourists as dive guides, boat operators, or work in small hotels.

Tourism is very popular in the park, with many visitors each year. People come from all over the world to scuba dive and snorkel in the clear waters, where the diving is famous around the globe. There are many places to stay, from simple cottages to large resorts.

Conservation and threats

Bunaken National Park was formally established in 1991 and is one of Indonesia's first marine parks. In 2005, Indonesia asked UNESCO to consider adding the park to the World Heritage List. Even with its protected status and funding, the park faces challenges like damage from fishing practices, diving, and trash.

Groups like the World Wildlife Fund help protect the park. In 2024, efforts were made in nearby Manado to stop plastic waste from reaching the park.
