One of Zamrud National Park's most captivating features is its twin interior lakes, Big Island Lake and Beruk Lake, which enhance the park's serene beauty. Within Big Island Lake, four smaller lakes, Pulau Besar, Pulau Tengah, Pulau Bungsu, and Pulau Hanyut, add to its mystique. Pulau Hanyut (Drift Island) is particularly fascinating, as its name suggests, it is believed to move freely over time, shifting with natural water currents. Additionally, the park is home to a bat sanctuary, where large colonies of fruit bats find refuge, further enriching its unique ecosystem. Whether exploring its floating lakes, dense forests, or thriving wildlife, Zamrud National Park offers an unforgettable glimpse into Sumatra's wild and unspoiled nature.Named Zamrud ("Emerald") for its lush green landscapes, the park is rich in swamp forests like Bengku, Rengas, and Pisang-Banana, providing a habitat for Sumatran tigers, sun bears, arowanas, and Belida fish. A birdwatcher's paradise, it hosts 38 bird species, including 12 protected species like hornbills and herons, thriving in its untouched wilderness.
