My wife and I are looking to relax for 4 days in a non-touristy or less touristy location following the 14 Day Greece Tour in early April. We have been to Santorini and Mykonos (obviously very touristy) and will have been on Hydra at the end of the tour. We will be using the ferries or public transportation or taxi. Is Hydra worth a return trip? Or is there another small coastal village or small island or scenic area that we should investigate? We appreciate your insights. Thank you.
If you do not need to return to Athens immediately after Hydra, the ferry that takes you back to Athens Piraeus stops first at Poros.

In the other direction it goes to Porto Heli or Ermioni in the Peloponnese.
From there you are 1 hour driving time to Nafplio
