I must confess that for many years I underestimated the beach at Gerontas. The comparatively long footpath didn’t seem to me to be worth the effort and in particular it seemed to be a winter’s tale. Gerontas had practically ceased to exist and simply had not roused my curiosity. The rumour was perfectly realistic since given the small scale of the beach, the surf in winter wouldn’t have to wash away all that much sand to completely destroy the beach. That happens occasionally here and there on Milos.
Gerontas still exists of course, as it always has and even if the beach lies on the land of the LAVA mining firm that extracts pozzolan there and even if it can only be reached on foot, I would now recommend a visit.
When driving by on the south coast road, from above you can see in particular the rock arch of Gerontas as well as the pozzolan mine of the firm of LAVA. The beach is mostly hidden from view.
After driving there in your two or four-wheel drive car, the sensible place for you to park is in the car park at the start of the gravel path to the beach at Katergo. The mine operators clearly indicate by signs where you can and cannot drive and where you may park, please. (And anyone who now asks why Katergo Beach is not shown in the website navigation will find the answer here.)
The footpath to Gerontas is difficult and very steep but very quickly mastered. When you get to the beach, a strip of nice sand and shallow, clear water awaits in front of a rock formation resembling terminal moraine. All this is flanked by steep cliffs.
