Traveling with a local - George was such an amazing tour guide that we booked 3 days of activities with him: 1. Poseidon’s temple snorkel, 2. Athens city tour and 3. Toured cities and archaeological sites outside of Athens. He’s friendly and does a great job of reading the group to decide what to do next. He was raised in Athens so he has a deep knowledge of the area, history and great restaurant recommendations. We’d use his tour group again!

It's worth doing even if you're a beginner. - Really nice day out. Very friendly and told us about the history of the area. Patient, as well as it was our first time snorkling. It was a lovely location we went to . It's worth adding the Posiedon trip on the day as well if you are intetersed in Greek history and the Gods.

Hire these guys - I cannot recommend these guys strongly enough. We booked a day trip with George and Amalia without knowing much about them. Was very impressed. George and Amelia drove us first to the Temple of Poseidon. During the entire trip, George was a wealth of information. He told us about the history of the area, stories of the cities we drove through, and put in the context of the things we were seeing. Afterwards we went for a nosy dive. When the boats had trouble and we had to cancel at Dive, George immediately thought of a great short Dive when she took us to. The diving was terrific. Safe, beautiful, leisurely and fun. My partner was able to snorkel while I was under the water and he had an equally enjoyable time. George went the extra mile and arranged for a make up Dive )for the canceled Dive due to boat issues) Evan took us out the second time. He is equally as friendly, informative and accommodating as his brother George. We dove a wreck this time while my partner snorkeled. I am impressed by their honesty, good-natured attitude, friendliness and helpfulness. You cannot go wrong with them. Thank you George, Amelia and Evan. We will see you next trip.

Above and beyond...and then some... - We can't say enough glowingly positive words about this tour. George and Amalia were incredibly responsive, accommodating and helpful. The snorkeling equipment was top notch. The scenery was beautiful. The experience was incredible. And to top it all off, George introduced us to an incredible local taverna in his neighborhood, off the beaten path and away from the tourists, for an unforgettable dinner with a panoramic view of pretty much all of Athens. AND on top of all of that George took us back to our hotel to grab our bags and took us to our new hotel to check in (we weren't able to get the same hotel for consecutive nights in Athens...long story). AND, even more, George introduced us to his incredible band's music and gave us an autographed CD as a parting gift. Quite simply, this tour added something to our trip we could never have experienced otherwise. 5 stars isn't enough. This is a day we will never forget, and we feel we have made potential lifelong friends in George and Amalia.

Amazing Diving Experience - We love Extreme Divers! Everyone was so accommodating and helpful. Our guide was amazing and even took photos of our dive. We loved this so much we booked again before we left Greece!

Enjoyable water adventure and history! - Amalia took us for a very enjoyable snorkel, followed by a drive down the coast to see Poseidon's Temple at Cape Sounion. She is an outstanding host, personable and kept it interesting. All necessary equipment was provided including wet suits. Highly recommended!

Excellent Tour!! - This tour was wonderful!! Amalia was an incredible guide. We say many fish and sea creatures while snorkeling. We enjoyed the history of the Temple of Poseidon. The Cape was gorgeous!! Highly recommend!!

Amazing Day - We decided on rather short notice to find a snorkeling experience for our anniversary while in Athens. The hotel set everything up for us which was nice. Evan met us at the hotel and showed us several beautiful spots down the coast. We loved snorkeling with him and discovering the beautiful waters and coastline. Next to the snorkeling we had some delicious treats and Evan gave us some nice tips for the remainder of our stay. I would recommend this to everyone and would definitely book another day of snorkeling fun!
