Founded as a bathing club in 1906, this world-famous stretch of sand with a perpetual party vibe is now owned by Doctor’s Cave Beach Club. It can get ­ridiculously crowded during the winter months, so if you’re going to make a day of it, arrive early to stake out your turf. Facilities include a food court, grill bar, internet cafe and water sports, plus changing rooms. You can rent shade umbrellas and inflatable air mattresses (lilos) for US$5, snorkel gear for US$5 and chairs for US$4.
