3 friend and I are going to Greece for 4 days in May. We will be spending 2 nights in Athens, 2 nights on an island, and then make our way to Turkey for a week. Does anyone have advice on what would be the best island to spend 2 nights on? We are 4 guys in our mid 20's and we are looking for the best combination of beaches + sightseeing + nightlife. We like to hike, backpack, kick it on the beach, scuba dive, moped, explore, etc. A fun nightlife is important, but we arent a bunch of drunkards and scenery and island exploration are what we're most interested in. At the same time making sure not to "waste time" taking extra long ferry rides. Our end game is to get to Bodrum, Turkey after 2 nights on an island. Any advice on direct ferrys from a Greek Island to Turkey? Or would I have to take a ferry back to Athens first? I have been to Greece before with my gf and went to Santorini and Paros. Both of which were great. Santorini seems more on the romantic side however. (great for couples, not so much for a guys backpacking trip).
