Discover two coastal jewels on a private day trip from Athens: the mineral waters of Lake Vouliagmeni and the cliffside Temple of Poseidon at Cape Sounio. This guided route combines easy walking, dramatic sea views, and time for photos or a quick dip.

The road south from Athens loosens into a coastal ribbon of pine and scrub as the Aegean opens to wide blue. On this private Sounio tour, travelers first step onto the warm stones around Lake Vouliagmeni — its thermal waters steam gently in cooler months and glint like glass in the sun — then follow the shoreline highway to the cliff-crowned Temple of Poseidon, where wind and sea argue for attention.

Bring cash for entrance fees
Entrance fees for archaeological sites and the lake are typically paid on-site; carry a small amount of cash or a card that works in Greece.
Sun protection is non-negotiable
Sounio’s exposed cliffs and the lakeside offer little shade — sunscreen, a hat and sunglasses are must-haves year-round.
Wear stable shoes
Stone paths and cliff edges at the temple are uneven; low-profile hiking shoes or sturdy sneakers improve safety and comfort.
Time it for late afternoon light
Arrive at the temple in the last two hours before sunset to avoid midday heat and to see the columns in striking silhouette.
Sturdy walking shoes
Needed for uneven stone at the Temple of Poseidon and lakeside paths.
Sun hat & sunscreen
