Hello, I have a questions about the easiest/cheapest way to get to and visit the Makronissos Tombs and Sea caves. Is there a bus stop near downtown/city center of Napa that gets me to Nissi beach, and perhaps then taxi on from there to tombs + the caves etc. or would walking be appropriate/possible from Nissi beach?. Is there a bus number or route that goes from Center Napa to Nissi beach. Thanks so much!
