The biggest highlight of visiting the Temple of Poseidon is the scenic views of the Saronic Gulf, from Athens to Cape Sounion, along the Athinon Souniou Road. Whether you travel by car or public transport, you can catch glimpses of many of the iconic UNESCO Heritage sites in and around Athens like the Temple of Zeus, the Acropolis, the archaeological site of Thorikos, Glyfada Beach, and more. You can take detours and explore these sites up close or continue your journey towards Cape Sounion.
