Access is by boat from the mainland, typically from Sihanoukville or coastal fishing villages. Charter boats are arranged locally; sea conditions and availability vary seasonally.

Tips for Visiting Koh Poulo Wai

  • Arrange transport and permits through Sihanoukville or local tour operators-these islands are remote and often lack regular services.
  • Bring reef-safe sunscreen and respect marine-protection rules-some islands have fragile coral.
  • Plan for limited facilities: most islands have no accommodations beyond rustic camps.
