Snorkeling in Nea Makri. This was a fantastic activity. The weather took a turn for the worse, after we arrived in Nea Makri, so it was not safe to go out on the boat. Dimitris offered us a full refund, or to tailor the activity to suit the weather and at a reduced cost. We chose the latter. Dimitris drove us to a beach, where we snorkeled for 2-3 hours close to the shore. 3 of our family of 4 had never snorkeled before and we absolutely loved it. It opened to us, a window into the underwater world - I will never look out to sea again without thinking about the wonderful world that lies beneath. Dimitris is a true professional - he is also very patient, and despite us being total beginners, we felt totally safe, with his obvious wide knowledge and experience about the area and snorkeling. He joined us in snorkeling, giving us so much information about the animals and plants under water. He is also full of local historical knowledge about an area where the Marathon race originated and on the way back from the beach he drove us via the site of The Trophy of the Marathon victory of the Greeks over the Persians which was hugely interesting. I cannot recommend Dimitris and Kanelakis Diving Experience highly enough. The snorkeling trip was the absolute highlight of our holiday in Greece.
