Sabang is the main town on Pulau Weh (Weh Island), a volcanic island about an hour's fast ferry ride from Banda Aceh. This is the westernmost inhabited point of Indonesia, and it feels like it — the pace is unhurried, the scenery is lush, and the underwater world is outstanding. Sabang town itself has a pleasantly faded centre with a scattering of colonial-era houses, remnants of its past as a coaling station for steamships.
The real draw is the water. The reefs around Iboih beach and the neighbouring Rubiah Island are among the best snorkelling and diving sites in Sumatra, with clear visibility and abundant marine life including reef sharks, sea turtles, and huge schools of tropical fish. Several dive operators in Iboih offer PADI courses and guided dives. The Sea Garden off Rubiah Island is accessible to snorkellers directly from the beach. On the island's northern coast, Gapang beach is another popular base with simple beachside bungalows.
Beyond the water, Pulau Weh has jungle-covered hills, geothermal springs near Jaboi, and a dramatic coastal road that circles much of the island. You can rent a motorcycle in Sabang town and explore the whole island in a day. The Kilometer Zero monument marks the symbolic western starting point of Indonesia's road network. The island is at its best from November to March, when the seas are calmest and visibility for diving is at its peak.
