The bay is surrounded by high cliffs and with its clear waters it is a good place for snorkeling. The beach is more quiet than the beach at Agios Nikolaos. Nanou beach is a an organized beach with sunbeds and umbrellas for rent and it is a pebble beach instead of a sandbeach.

The farthest end of the beach from where you get off the taxi boat from Symi harbour is discrete nudist beach.

On some of the small beaches and coves that aren't too visible from the main road nudism is tolerated, maybe less in high season.

Agios Vasilios Beach -
This beach, the Agios Vasilios or Lapathos Beach, cannot be reached by water taxi (except as I understand for wednesdays in the high season). If you want to visit the beach the only way is by foot. The walk takes a couple of hours. It is a remote and quiet beach without any facilities, which means that you have to bring your own water supply and something to eat. Because it is so remote and quiet it is an ideal naturist beach. It is made out of pebbles and just a few bits of sand. At the beach there are a couple of trees where you can get some shade (so no umbrellas & sunbeds). The last part of the walk you is a rather steep and a bit slippery climb down, so it is adviced to wear good walking shoes.
Toli Bay Beach -
Toli Bay is situated on the north coast of Symi, west of Emborio. You can go there by scooter or by car. Keep right when going up hill a few km after leaving Chorio. The road is in good condition - keep your eyes open for a footpath leading down to the left of the road. The walk downhill takes about half an hour. There are 4 beaches in the area. Toli Beach is divided into two beaches, and one of those beaches is a naturist beach. There are no facilities here like sunbeds and umbrellas but I was told that there is a taverna nowadays.
