Beaches -- Ayia Marina, signposted and about a 30-minute walk east of Spetses town, is the best, and busiest, town beach. It has a number of tavernas, cafes, and discos. West of Spetses town, Paradise beach is crowded, littered, and to be avoided. On the south side of the island, Ayii Anaryiri has one of the best sandy beaches anywhere in the Saronic Gulf, a perfect C-shaped cove lined with trees, bars, and tavernas. The best way to get here is by water taxi. Whichever beach you pick, go early, as beaches here get seriously crowded by midday.
Fans of The Magus may want to have a look at the beach at Ayia Paraskevi, which is bordered by pine trees. Located here are a cantina and Villa Yasemia, residence of The Magus himself. West over some rocks is the island's official nudist beach.
