The Red Lake is the largest barrier lake in the Eastern Carpathian Mountains. It is located in the foothills of the Hasmasul Mare Mountain, near the Bicaz Gorges, and it was formed after the collapse of a slope caused by an earthquake in 1838.
The Red Lake got its name from the nearby Red Creek, which is filled with various alluvia of a reddish color, such as iron oxides and hydroxides.
The lake is a great tourist attraction, having a valley that is safeguarded by strong winds. The clean and rich air and the picturesque surroundings offer great conditions for relaxation, and near the lake, there are several merchants who sell souvenirs and local street food.
