For those who are thinking of traveling by bus/bicycle/motorbike along the East coast of Sri Lanka from Mulativu - Trincomallee - Batticoloa -Arugam Bay, the lagoon at Pulmuddai/Kokilai should not be a deterrent.
Kokilai Lagoon, Kokilai. The other side of the lagoon is Pulmoddai |
If you are traveling in vehicles larger than a tuk-tuk there is detour (42 km ) around the Kokkilai Lagoon. It should be motorable even by a small car during the dry season. During the rainy season, as some sections of the road are gravel, small cars might not be able to go over potential mud holes.
