Lake Eacham is a clear, blue lake surrounded by lush rainforest and is a popular swimming spot. Walking tracks through the rainforest provide secluded forest-fringed views of the lake and excellent opportunities for viewing wildlife.
In geological terms, the lake is a maar—a volcanic crater formed by massive explosions from the superheating of groundwater. The crater has filled with water, forming a lake 65m deep. A number of rainforest communities can be seen along the 3km track encircling the lake.
Over 180 bird species have been recorded from the rainforest and one of the few species of marsupial active during daytime—the small musky rat-kangaroo.
