I will be in Athens for work at the end of October and will have about a week after to do some exploring. I am thinking of basing myself in Nafplio as there seems to be a ton to see in the area and I haven't been there before.
My question is as I am not planning on renting a car, how easy is it to join up with group day tours to nearby sites like Epidavros and Mycenae? I know they would be easy to access with a rental car and there are set trips offered by large tour operators like Viator, but they are very expensive and typically require 2 pax minimum (I am traveling solo). I am hoping that on the ground in Nafplio it will be easy to find such tours from local travel agencies. Please let me know if that is the case or if I should reconsider renting a car.
