Sandy Meloneras beach, at the west end of the seafront walk along the Meloneras coast, is a lovely place to spend a day and the strip of terrace restaurants right by the sand are spectacular at sunset.
Because Meloneras beach is at the end of the boulevard, it's nowhere near as busy as the stretch close to the Maspalomas lighthouse. The sunset, however, is just a spectacular.
Amongst the restaurants, La Esquinita del Mar and Hemmingway II makes it into the Tripadvisor Top Ten for Meloneras, while the Ciao Ciao Italian is always of reliable quality (and does a smiley-pizza for the kids). The Sunset Cafe is right at the top of the Meloneras Playa shopping centre with fabulous views of the whole area.
