Ferry schedules can change.  Wind, rough seas, and seasonal schedules may affect departures, so avoid planning tight connections.

 

Book the Acropolis in advance. Timed-entry tickets can sell out during peak season, especially in summer.

 

Ask before drinking tap water. ​​Tap water is safe in Athens and many mainland destinations, but bottled water may be recommended on some islands.

 

Follow local bathroom etiquette. Some plumbing systems cannot handle toilet paper. When you see a sign or waste bin beside the toilet, use the trash bin instead.

 

Wear sturdy shoes at ancient sites. ​Ancient sites often have uneven stone, steep steps, and slippery marble, so comfortable shoes with good traction are a must.
