Batu Islands

An archipelago in the Indian Ocean off western Sumatra, the Batu Islands sit on the equator between Nias and the Mentawais, and are known to surfers by the shorthand "the Telos." The three main islands, Pini, Tanahbala and Tanahmasa, are surrounded by scores of smaller islets and a maze of reef passes.

Surf here is a boat-access affair, with waves scattered across reef breaks that produce clean lefts and rights of varying intensity. Some passes offer long, mellow walls ideal for intermediates, while others draw serious water over shallow coral for barrel-hunting experts. Because the islands are spread out, charter boats and a handful of remote camps are the usual way to reach the best peaks, and lineups are often uncrowded.

The main season is April to October, when south-west groundswells and offshore trade winds combine to groom the exposed reefs. Straddling the equator, the group enjoys warm water and a tropical climate year-round, though the wet months bring more variable winds.

Life here is low-key and off-grid, built around fishing villages, coconut plantations and the rhythm of the tides. There is little infrastructure beyond the surf camps and charter operations, which is precisely the appeal for travellers seeking isolation and consistent, quality waves without the crowds of Bali or the price of the Mentawai luxury boats. Access typically runs through Nias or the Sumatran port of Sibolga, followed by a boat crossing, so most visitors arrive on organised trips rather than independently.
