Labuan Cermin Lake, the Perfect Place to Witness the Natural Beauty of East Kalimantan

Labuan Cermin Lake, located in the Biduk-Biduk district of Berau Regency, East Kalimantan, Indonesia, is a hidden gem that has captivated the hearts of many travelers and nature enthusiasts.

Known for its crystal-clear waters and stunning natural surroundings, this lake offers a unique experience that showcases the pristine beauty of East Kalimantan. This article delves into what makes Labuan Cermin Lake so special and why it should be on every traveler’s bucket list.

The Unique Appeal of Labuan Cermin Lake

1. Crystal-Clear Waters

Labuan Cermin, which translates to “Mirror Lake,” is aptly named due to its exceptionally clear waters that create a mirror-like reflection of the sky and surrounding forest.

The lake’s clarity is so remarkable that the bottom is visible even at depths of several meters, giving the illusion that boats and swimmers are floating on air. This visual spectacle is a photographer’s dream, offering countless opportunities for stunning snapshots.

2. Dual-Layered Water

One of the most fascinating features of Labuan Cermin Lake is its dual-layered water composition. The top layer of the lake consists of fresh water, while the bottom layer is saltwater.

This phenomenon is due to the unique geological conditions of the area, where fresh water from surrounding rivers and rainwater mixes with saltwater from underground sources. The distinct layers are visible to the naked eye and create an extraordinary swimming experience, as the temperature and buoyancy change dramatically between the layers.
