Take a guided bus tour or local bus towards the park and enjoy moderate hikes around the legendary Greek mountain; park open daylight hours, best to start early.
Spend your remaining days enjoying Athens at a more relaxed pace. Activities could include day trips to nearby coastal towns like Glyfada or Vouliagmeni, visiting additional museums such as the Benaki Museum or Museum of Cycladic Art, attending theatre performances, and trying a variety of Greek dining experiences. Use buses and metro for budget-friendly travel and balance culture with chill beach days and fun nightlife.
