The lake occupies a volcanic crater formed approximately 4,000 years ago.
In Roman mythology, Virgil identified this lake as the gateway to the Underworld in the Aeneid.
The name 'Avernus' is derived from the Greek 'aornos,' meaning 'without birds,' due to the ancient belief that birds died when flying over its toxic volcanic vapors.
Agrippa used the lake as a base for his naval fleet, the Portus Julius, by connecting it to the nearby Lake Lucrino via an artificial canal.
The remains of the so-called 'Temple of Apollo' are actually a large thermal bath complex dating back to the Roman period.
The water depth of the crater lake reaches approximately 34 meters.
The lake area serves as a habitat for various migratory bird species, contradicting its ancient reputation.
Surrounding vineyards and orchards contribute to the local volcanic soil viticulture.
Lake Avernus is a volcanic crater lake located within the Phlegraean Fields, historically significant for its role in Roman mythology as the entrance to the Underworld. The circular lake is encompassed by a perimeter path that facilitates walking and cycling. The surrounding landscape features the ruins of the Temple of Apollo, a large vaulted Roman structure. Several agriturismo establishments and restaurants line the perimeter, offering views of the water. The area is characterized by its distinct geological history and calm, contained crater geography. It remains a protected natural site within the regional volcanic park system.

Wear sturdy walking shoes to navigate the unpaved sections of the crater perimeter.
Bring sun protection as the path has limited shade during peak summer hours.
Visit during the shoulder seasons to avoid intense heat trapped within the crater.
Do not attempt to swim in the lake, as the water quality is frequently monitored and not designated for recreational swimming.
Maintain silence to respect the natural preserve status; carry out all trash to keep the crater clean.
