Underwater Labyrinth

Imposing rock, thermal waters, underwater tunnels, and lush vegetation create this beautiful and unique geological phenomenon along the Athenian River. 

A visit to Lake Vouliagmenis is a well-rounded experience with recreational activities including swimming through the thermal waters, snorkeling, hiking along the rock formation, access to a spa, and both public or private dining options along the water. 

Only 30 minutes from the city center, this natural wonder will definitely be on my list of day trips the next time I am in Athens.
