A walking path circles the entire lake with nature huts that describe the unique animals and plants inhabiting the crater. On one end of the trail, the ancient Grotto di Cocceio is off-limits to visitors, barred by gates and overgrown brush. Closed to the public due to structural dangers, this Roman military tunnel once connected the lake with the Greek acropolis of Cuma.
On the other side of Lago Averno, next to the vineyards, a Temple of Apollo juts out from the ground. Thirty feet of dirt buries this temple due to bradyseism -- the rising and falling of the ground due to the ebb and flow of magma chambers deep within the earth. Only the dome can be seen, but its massive proportions show that this building once towered several stories high. Very likely, the name ‘Temple of Apollo’ is a misnomer. The Romans more likely used this structure as a thermal complex for bathing. If true, this structure shows how technologically advance the Romans had become to harness the hydrothermal activity of this region.
