We had a great day with Nikolaos. We arrived from the US in the morning and he picked us up at the Athens airport. The airport is between Athens and Corinth, So Corinth is a good choice for a day excursion (we did an all day Athens tour the next day). We went to Acrocorinth, the ruins of old Corinth. Very interesting place, not nearly as crowded as the acropolis. There is a nice museum there with some great pottery. We also saw the Corinth canal. After lunch, which was at a lovely local restaurant recommended by Nikolaos, we went to Nemea for wine tasting. The wines there were excellent and the host at the winery was very friendly and informative. After that, Nikolaos dropped us at our hotel in Athens. Nikolaos is a wonderful guide and shared a lot of information about Greece, Greek history, and a variety of topics. This is a really good tour if arriving in the morning and looking for something to do until check in time at the hotel, especially if you have time to see Athens another day.
