Hon Dua Islet

Hon Dua is a named coastal islet in the Ban Than–Hon Mang–Hon Dua national scenic landscape of Tam Hai, now in Da Nang. Its principal value is its relationship to the striking exposed-rock coastal setting.

Overview

Understand the island as a complete place, not a single attraction.

Hon Dua is one of the two named islets in the Ban Than–Hon Mang–Hon Dua landscape of Tam Hai. The complex is recognized nationally for its scenic coastal geological character, with distinctive exposed rocks and marine erosion forms. It was listed as a provincial scenic relic in 2017 and recognized as a national scenic relic under Decision 393/QD-BVHTTDL of 24 February 2023. This profile treats Hon Dua as a separate named islet but does not assign unsupported dimensions, population, beaches or independent conservation designations to it. Visitors should understand Hon Dua together with Hon Mang and the Ban Than coastal headland, while respecting sea conditions and local site-management requirements.

Key things to understand

  • A small rocky islet defined by its place in a distinctive paired-islet coastal landscape.
  • The wider complex is known for exposed, sea-shaped rock surfaces; detailed Hon Dua-specific geological surveys were not verified.
  • Its recognition is tied to the shared Tam Hai scenic landscape rather than an independent historical settlement.
  • Hon Dua is a separate named islet from Hon Mang, but both share one protected scenic-landscape context.
  • Do not assume unrestricted landing or visitor access.
