I walked along the beach from Perissa Beach to Red Beach. It took about 4 1/2 hours but it was 4 1/2 hours of adventure and fun. We did not walk back but instead took the bus from Akrotiri (near Red Beach) across the island to Fira. Once on the beach I was intregued to find that the sand on the beach was indeed red. I was told it was from a volcanic eruption on the island a long time ago.
Equipment: We took along sandals, money, cameras, sunblock, and bought drinks at stops and resorts along the way.
Perissa Beach is a beautiful black beach where one can leisurely pass the time away. It is recommended for all who just like to take life easy. Perissa Beach is easy to get to and the water there is magnificent. It is a great place to get a tan. If it gets too hot, just jump in the water and cool off.
Equipment: Bring along sunblock, swim truncks (or boardshorts) or a bikini which many people only half wear. Sandals are also a must as the black rocks get quite hot.
Red Beach is one of the most impressive here, though is a bit crowded (you can go walking) and is a pebbles beach. There is a food stall and some facilities. Go early, it's a small beach.
The white beach is the next to Red Beach wetwards. Is small too, but less crowded, as you can only get tere by boat. There are fishermen boats every hour from the bach near Akrotiri ruins.
