Mursala Island is a forested island off the western coast of North Sumatra, Indonesia. It is notable for a waterfall that reaches close to the shoreline and for its coastal natural scenery.

Visitors go to see the beach and the waterfall feature, explore coral reefs for snorkeling and observe the island’s tropical vegetation. The island is uninhabited or sparsely inhabited and lacks large visitor infrastructure.

Mursala Island has been used for local tourism and day trips and is approached by boat from mainland ports. It is part of the coastal island chain off western North Sumatra and is managed under Indonesian regional jurisdictions.

The island lies off the western coast of North Sumatra in the Indian Ocean near the port city of Sibolga. It is reached by small craft from the mainland and sits within the tropical maritime environment of western Sumatra.

  • Coastal waterfall: Known for a waterfall that drops directly near the shoreline, creating a distinctive landform and beachside cascade.
  • Access: Access is by boat from the nearest mainland ports in western North Sumatra, typically the city of Sibolga or nearby coastal towns.

What to See #

  • Waterfall site: A coastal waterfall that plunges to a small shore pool and adjacent beach area, framed by forested interior slopes and fringing coral reef.
