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. There are basic private rooms at the PHPA post at Tanjung Pasir on the south coast, where most boats from the mainland arrive. Renting a fishing boat from Tanjung Pasir and going fifteen minutes east to Stama reeft is very rewarding, with lots of sharks and turtles. There’s nowhere on Moyo to rent masks and snorkels so bring our own; fins are advisable due to the strong currents.
Moyo island has become more famous with the visit or Princess Diana of England who sought refuge on this island from the paparazzi. The main attraction of this island lies beneath the surface of the ocean. Moyo is surrounded by beautiful untouched coral reefs which are ideal for snorkeling. Swim with white tip reef sharks, dive next to blue spotted sting rays, encounter a school of tropical fish. These experiences in the tropical warm waters of Indonesia will be unforgettable.
Back on land, two thirds of the island is a game reserve. Wildlife here includes deer, feral cattle and a variety of different types of birds. From great billed herons, spotted brahminy kites to white bellied sea eagles – bird watchers will be in for a treat with the amount of birds that make this island their home. Archeology and cultural buffs shouldn’t miss a visit to Batu Tering traditional village where you can see the remains of an extinct megalithic culture. After you check in with the village chief, ask for a guide to show you round Airnung where you can see the remains of old rulers and ancient relief carvings.
The coastline has some beautiful beaches of fine coral sand and not the black volcanic sand like we find on a lot of islands in the archipelago. There are beautiful coral reefs, which make it excellent for scuba diving or just snorkeling. The reef at the southern end of the island is probably the best of all. There are a few inhabitants on the island and this consists of around 21 villages concentrated in the northern end. From Moyo there are splendid views of Mount Tambora (2,821m) to the east, the highest mountain in Sumbawa, which erupted quite violently in 1815 but now has amazingly beautiful forests on its western slopes.
Tambora can be climbed from the side in three days and is well worth a visit. It has an enormous crater and within, a two-colored lake. From the crater there are also spectacular views over Saleh Bay and the rest of Sumbawa to the east, and to the west, Moyo Island to Lombok and Mount Rinjani. The wildlife on the reserve has adapted to the fairly dry habitat and these include Deer, feral cattle, and numerous birds such as Orioles, Sunbirds, Coequals, Koels and Drongos. Of course there are several species of shore birds along the coastline.
