What is avernus lake?

Avernus Lake, also known as Avernus Crater, is a volcanic crater lake located in the Campi Flegrei region of southern Italy near the city of Naples. It is approximately 2.5 miles in circumference and has a depth of around 200 feet.

In ancient mythology, Avernus was believed to be the entrance to the underworld, and the lake was thought to be bottomless and a place for the dead. The ancient Romans named it after the Greek god Avernus, who was associated with the underworld.

Today, the lake is a popular tourist destination due to its picturesque scenery and rich history. It is also a popular spot for birdwatching, as many species of birds can be seen around the lake. The lake is currently protected as part of the Campi Flegrei Regional Park, which is dedicated to the preservation of the area's unique natural and cultural heritage.
