In the very heart of the city of Tarakan lies a wonderful natural corner — the Mangrove and Proboscis Monkey Conservation Area (KKMB). This unique 22-hectare reserve is a rare combination of untouched wilderness and a research center located right amidst urban development. Here, a fragile ecosystem of mangrove forests is preserved, which protects the coast from erosion and strong winds.

The main treasure of the reserve in the country of Indonesia is its inhabitants — the Bekantan monkeys (Nasalis larvatus), also known as proboscis monkeys. Locals humorously call them "Dutch monkeys" because of their characteristic long noses. These primates are endemic to the island of Kalimantan (Borneo), and observing them in their natural habitat is a truly rare and exciting experience.
Strolling through the reserve, you will see trees that are hundreds of years old. At least 11 species of protected animals live on the territory, making this place an important living laboratory for scientists and a true paradise for ecotourism enthusiasts. It is not just a park, but a symbol of nature conservation within a modern city.
