First stop would be Cave Agia Sofia. Just look for the sign and tour busses parked along the street. Agia Sofia is just south of Topolia. It is a nice walk on comphortable stairs (no flip-flops, please!) realy worth a walk.
Cave is up inside of the mountain and it is really huge. There is small chapel inside and a place where I guess people pray for a good health because there was lots of glasses left by those who.... got ther 20/20 vision back... There is also a bell you can ring when you make your wish and a sleeping dog.....go figure. We were lucky and spoted a mountain goat.
