While Emerald Heart Island (more notably known as Cocks Comb Island) is technically in Myanmar, it’s an easily accessible day trip from Ranong in Thailand.

A 1 and a half hour’s ride away from Ranong, it’s easy to see how the island got it’s Emerald Heart moniker – through drone view, the ocean lagoon within the island resembles an emerald-coloured heart!

Where is Emerald Heart Island (Cocks Comb Island)?

Without further ado, let’s dive right into how to explore Emerald Heart Island.

1. Get into the ‘Hidden Lagoon’ by going under the caves!

One of the most fun parts of visiting Emerald Heart Island that we’ve heard from travellers, is that before you even get to reach the best part of the island – aptly named the Hidden Lagoon, you’ll actually have to go under the limestone caves first.

Some are able to take a boat through the caves where there’s space between the water and rock ceiling, while some choose to snorkel their way through the small cave!

2. What do people do here?

The main thing most travellers do here is snorkel is snorkel – and whether you’re more comfortable snorkelling in shallow waters, or if you love snorkelling in deeper waters where there’s ton of underwater life to be discovered…

Emerald Heart Island gives you the best of both worlds.

When you snorkel/dive, you’ll be pleasantly surprised to see everything from…

…large schools of fish…

…little black tipped reef sharks (not dangerous!), moray eels, turtles, giant clams, sea anemone and clownfish, corals and more!

PS: We’ve heard that while a lot of the coral is dead due to bombings many years ago and illegal taking of ocean life – the wildlife to be discovered here is still fantastic.

3. It’s a fantastic dive site with great visibility too!

Little known to most people, Emerald Heart Island is actually a pretty great dive site too. In the limestone rock at the water’s edge, you’ll find openings where you’ll be able to dive in at a shallow 2-3m depth.

Once in, follow the shafts of light that will point you to the hidden lagoon. When you’re in the lagoon, you’ll find that it has a maximum dive depth of 12-15m with some coral blocks to check out.

PS: If you’re an inexperienced diver who’s more comfortable doing shallow dives, we’d recommend checking out the coral plateau that’s only at a depth of 1-2m with great visibility!

4. There are other activities you can do, apart from snorkelling and diving

If you’d like more bang for your buck, you may experience kayaking here too!

For the less active, feel free to simply float around the gorgeous waters of the island and get some great Instagram shots while you’re at it. 😛

There’s even a viewing platform in the hidden lagoon, if you’d like a higher vantage point to take it all in from.

Of course, if you’re here to take Instagram shots too, Emerald Hearts’ Hidden Lagoon makes an incredible place to get those super mermaidy photos.

5. It’s the ultimate border-crossing thrill!

If you’ve ever wanted to get more stamps on your passport from a single trip, Emerald Heart Island is one way to do it.

Getting here from Ranong in Thailand means you’ll actually have to get a Border Pass, or Visa for Myanmar, so that you’ll be able to, well, cross borders to Emerald Heart Island. (Even if it’s only 1 hour and a half away!)
