Moyo Island, at the mouth of Saleh Bay, has a nature reserve with wild oxen, deer, wild boars and a great variety bird species. Visits are best made during the dry season from June through August. A few kilometers of the north coast of Sumbawa, the national park island of Moyo Island is probably the most rewarding destination in Sumbawa, surrounded by beautiful coral reefs and home to wild pig, monitor lizards, 21 species of bat, huge herds of native deer and hordes of crab-eating macaques. The best time to visit is in June and July, though the seas are clear and quiet from April. A natural Eden on land and sea. Unparalleled scuba diving and sea life in the Flores Sea, with pristine beaches and jungle waterfalls.
