Tioman is the only significantly mountainous island of several scattered off Peninsular Malaysia’s east coast. Despite being a popular holiday island, the forest remains very wild and is home to some endemic species. Most visitors to Tioman get their first view of the island’s peaks from the boat over from Mersing.
Gunung Jerai is a very striking limestone mountain surrounded by flat land and located on Malaysia’s west coast. In ancient times it was used as a navigational aid by traders from overseas and allegedly was once an island called Pulau Serai. It was also previously known as ‘Kedah Peak’ and is normally clearly visible from Penang.
Ili Ujolewung is one of the best of the ‘less high’ mountains in Indonesia. Although infrequently climbed, the grassy terrain allows spectacular views across Lembata island, including the smoking volcano, Ili Ape (Lewotolo), to the west. The mountain is no longer active, but an ancient, shallow crater still remains clearly visible at the top. There is also a very old vegetable garden which is passed by the trail, apparently a historical place of retreat during wartime or to avoid capture by slave traders.
Gunung Ranai is the highest peak of Natuna Besar island, a remote island in the South China Sea between Borneo and the mainland Malaysian peninsula. Ranai is simultaneously the most isolated Ribu on the list, but also the Ribu closest to an airport. Given its isolation, it is not surprising that there is some fascinating flora and fauna to be spotted on Natuna Besar. Lucky hikers will spot bright red terrestrial crabs, numerous pitcher plants and maybe even the very rare and endangered primate known locally as the Kekah.
The large, forested Pesawaran – Ratai mountain range lies to the southwest of Bandar Lampung yet it is very rarely climbed by hikers – our trip here was the first since 2007! From the summit ridge of the highest peak Ratai there are excellent views to surrounding forest and the Lampung coastline and you will almost certainly hear the calls of siamangs who live in this remarkably wild area.
