The short answer
Koh Rong Marine National Park: what visitors should know first
You are already in it once you land, so the question is how to behave. Snorkel or take a boat tour with a reputable operator, avoid touching coral, and take rubbish off the island. Do not expect a visitor centre or set trail, and check current rules locally.
History and context
The story behind Koh Rong Marine National Park
The park was established in February 2018. Wikipedia lists the islands as Koh Rong, Koh Rong Sanloem, Koh Oun, Koh Song Saa, Koh Tatiem, Koh Touch, Koh Manoa Krav and Koh Manoa Knong, though it refers to seven islands, so check the official count.

Why it matters
Why Koh Rong Marine National Park is worth your time
Wikipedia records that the Koh Rong archipelago was designated Cambodia's first marine national park in February 2018, covering about 524 square kilometres of land and sea under the Ministry of Environment. It is also an Important Bird Area, valued for its Malaysian plover population.
For visitors, that status means the island's beauty is something to guard. Wikivoyage mentions deforestation and waste in the sea, so each choice, from the boat you take to the straw you refuse, has a small effect. Understanding the park also helps you pick quieter, better-run operators.

Plan your visit
How to experience it
The park covers a group of islands and the sea around them, with Koh Rong and Koh Rong Sanloem the best known. Because the sources describe no formal visitor centre, the practical way to experience it is through a resort or dive shop that runs boat trips, snorkelling or diving.
Choose a small group and a calm day. Ask the operator which sites they use, whether they have life jackets, and what they do about rubbish. A morning trip is usually best, with calmer water and cooler air. If you do not swim, a boat ride along the coast is still worthwhile for the rocky headlands and islets.
On land, behave as though you are in a protected area: stay on tracks, do not take shells or coral, and keep fires and plastics off the beach. Rules and zones can change, so ask your accommodation for current guidance.
Plan with confidence
Small decisions that make the visit easier.
- Choose operators that give life jackets and brief you on reef rules
- Go on calm mornings between November and March
- Never touch or stand on coral
- Take your rubbish back to the mainland
- Ask your resort about current park rules
