Athens: Marathon Cape and Bay of Schinias Snorkeling Trip — A Detailed Look
If you’re planning a trip to Athens and craving a break from the bustling city streets, a snorkeling adventure in the nearby waters might just be your perfect escape. This 4.5-hour tour takes you on a speedboat journey to explore the hidden coastal gems of Marathon Cape and the pristine Bay of Schinias. While we haven’t personally been on this trip, the glowing reviews and detailed itinerary paint a compelling picture of what to expect.
What we love about this experience? First, the small group size (limited to just 7 participants) promises personalized attention and a relaxed vibe. Second, the guides’ expertise, often praised for their friendliness and knowledge, can make the difference between a good outing and a memorable one.
