Cerro Azul is particularly popular among surfers. The waves are gentle for the beginners, but even more advanced surfers appreciate the famous "left wave". Cerro Azul even gets mentioned in the Beach Boys song Surfin' Safari: "They're anglin' in Laguna in Cerro Azul ---From Hawaii to the shores of Peru".
Apart from beach, surfing and bodyboarding other popular activities in Cerro Azul include fishing and watching the sunset from el muelle, deck. There is a small market too, where you can buy fish for a homemade ceviche - a mandatory element of a beach trip in Peru. I also recommend to stop and by fresh figs if they are on the season (February). They sell them in small stands alongside of Panamerican highway in Chilca, approximately at the km 64.
On Friday night and Saturday morning the beach was still relatively unpopulated, although Cerro Azul is a very popular summer destination for limeños. But on Sunday the beach was packed with both locals and visitors. There was a live music concert in the market, sand scuplture artist at the beach and a whole bunch of surfers riding the waves.
