Marble Beach is a sheltered bay on Koddiyar Bay, about 16 km south of Trincomalee town on Sri Lanka’s east coast. It is run by the Sri Lanka Air Force, which keeps the beach clean and operates a small resort here, and it is known for exceptionally clear, calm water where you can see the seabed from the shore.
There is a public beach area for day visitors, and the resort’s restaurant and bar are open to guests. Go between about May and September for the calmest seas.

History of Marble Beach
The beach lies on land controlled by the Sri Lanka Air Force near its China Bay base, which is why it was off-limits or little known to tourists for many years. The Air Force opened it to visitors and now runs the Marble Beach resort, including rooms, The Yacht Restaurant and a bar.
The name is usually put down to the glassy, marble-like clarity of the water in the bay. Because access is controlled, the beach has stayed cleaner and quieter than many others on the coast.
Attractions at Marble Beach
- Clear, calm water: a sheltered bay that is often flat enough to see the bottom from the shore.
- Clean beach: a tidy stretch of sand maintained by the Air Force, with lifeguards on duty at the public area.
- Green headlands: wooded hills frame the bay and make a pretty backdrop.
- Resort facilities: an Air Force-run resort with a seafood restaurant, a bar and water-sports activities.
Things to Do at Marble Beach
- Swim: one of the safest swimming spots around Trincomalee in the calm season; stay within the area watched by lifeguards.

- Lunch with a view: eat at the resort’s restaurant, or bring a picnic and take all rubbish home.
Marble Beach – Entry Eligibility and Open Timings

- Best season: about May to September; seas can be rough during the northeast monsoon (roughly November to February).
- Rules: dress modestly away from the water and don’t photograph military areas.
How Long to Spend at Marble Beach

How to Get There
- From Trincomalee: about 16 km south via the Kinniya road and China Bay; a tuk-tuk or taxi takes around 30–40 minutes. Agree a return trip, as transport back can be hard to find.
- From Colombo: Trincomalee is roughly 6–7 hours by road, or take the overnight train from Colombo Fort, then continue by tuk-tuk.
- From Nilaveli or Uppuveli: allow about an hour by tuk-tuk through Trincomalee town.
Arriving at Colombo Airport (CMB)? It is a long drive to Trincomalee, so Book a fixed-price airport transfer straight to your hotel.
