The Spermonde Archipelago is a scattered group of coral islands, islets and reefs off the southwest coast of Sulawesi, Indonesia, near the city of Makassar in South Sulawesi. The archipelago is composed of numerous low-lying islands and submerged reefs that form a maritime zone important for fisheries and local livelihoods.

Key features are shallow coral reefs, seagrass meadows and numerous small islands used for fishing villages, day tourism and marine activities. Many islands are accessible only by boat and are popular for snorkeling, diving and short boat trips from Makassar.

Settlement patterns in the archipelago range from uninhabited islets to small fishing communities living on wooden houses and relying on reef and pelagic fisheries. Over time the area has remained primarily marine-focused, with limited permanent development on most islands.

Geographically the archipelago lies off the southwestern shoreline of Sulawesi in the Java and Flores Sea region, with the city of Makassar serving as the main regional hub for transport and boat services to the islands.

  • General location: Comprises a chain of coral islands and reefs off the southwest coast of Sulawesi, administratively part of South Sulawesi and close to the city of Makassar.
  • Marine life: Marine biodiversity includes coral reefs and seagrass beds; many islands are visited by day-trip boats for snorkeling and fishing excursions.

What to See #
