Within Penang National Park, this picturesque beach is named for the macaques that live in the surrounding forest. The water is safe for swimming, and if you’re lucky you’ll see a sea turtle. On weekends the beach is popular with families, who set up their picnics on the pristine white sand. The Muka Head Lighthouse is about a 40-minute walk from Monkey Beach. The trek is worth it for the sweeping sea views once you reach the lighthouse.
