Playa d’en Bossa is the most famous and busiest beach in Ibiza, but definitely not the nicest beach. In fact, Ibiza has a lot of wonderful beaches (and if you see them, you forget Playa d’en Bossa). The most fun is to explore several of these beaches, not to show up every day at the same beach. In one week you don't have enough time to visit all the beaches, but you shouldn't miss Cala d'Hort (where you have stunning views of Es Vedra, the famous mystic rock on the coast of Ibiza), Benirras (at the north side of the island, lovely quiet) and Ses Salinas (a bit busier, but here you'll find a lovely wide beach with very nice beach bars). Especially on Sunday is the luxurieus Blue Marlin beach a real winner! The fantastic El Chirinquito is also really worth a visit for the real epicurean.
