Between the Tides: Discovering Havelock Island’s Intertidal World

An easy nature walk from Emerald Gecko Resort into the fascinating world between land and sea

When most people think about exploring the Andaman Islands, they imagine scuba diving, snorkelling, kayaking or walking along a beautiful tropical beach.

But there is another world that appears twice every day — and you don't need a boat, diving certificate or expensive excursion to discover it.

You simply need to look down.

Here at Emerald Gecko Resort on Havelock Island (Swaraj Dweep), the changing tide creates a wonderful opportunity for an intertidal walk and tide pooling, right outside the resort.

It is one of those simple island experiences that can easily be overlooked.

And yet, once you start looking, you may find yourself wondering why you didn't notice it before.

First: What Exactly Is the Intertidal Zone?

The intertidal zone is the strip of coastline that is sometimes covered by seawater and sometimes exposed to air.

In other words, it is the area between the high-tide and low-tide marks.

The reason it exists is, quite simply, the tide goes in and out.

For anyone accustomed to city life, tides can seem slightly mysterious. They aren't like a clockwork wave arriving every few minutes. The sea level rises and falls over several hours, influenced mainly by the gravitational pull of the Moon and Sun.

So the beach you see in the morning may look surprisingly different a few hours later.

At low tide, the sea retreats and reveals a landscape that is normally hidden beneath the water.

That is when the exploring becomes interesting.

A Walk Between Two Worlds

At low tide, the edge of the sea becomes a kind of natural outdoor aquarium.

Rock pools hold seawater.

Small channels run between rocks.

Wet sand glistens in the sunlight.

Seaweed clings to stones.

And creatures that spend much of their lives underwater suddenly find themselves exposed to the air.

This is the intertidal zone — an environment where marine life has evolved to cope with constantly changing conditions.

It can be hot.

It can be wet.

The water level changes.

The waves can be powerful.

And yet life thrives here.

What Might You Find in a Havelock Tide Pool?

Every tide pool is different, and that is part of the fun.

Look carefully and you may discover tiny fish darting through shallow water, small crabs disappearing sideways beneath rocks, molluscs attached to stones and other small marine creatures hiding in crevices.

Depending on the location, tide and season, you might encounter:

• Small reef and tide-pool fish

• Crabs and hermit crabs

• Snails and other molluscs

• Limpets and barnacles

• Sea cucumbers

• Small sea stars

• Anemones

• Seaweed and algae

• Tiny shrimp and other crustaceans

• Shells and traces left behind by marine life

And sometimes you find something that you weren't expecting at all.

That's the beauty of a tide pool.

There is no guarantee.

You have to look.

Havelock Island's Other Aquarium

Snorkelling gives you a wonderful view of the underwater world.

Tide pooling gives you something different.

You are standing above the creatures rather than swimming beside them.

There is no mask.

No fins.

No tank.

No boat.

Just a pair of comfortable shoes, a little patience and a willingness to get curious.

For families, it can be especially entertaining. Children who might walk past a beach without noticing much can become completely absorbed by a tiny crab or fish hiding in a rock pool.

It is also a wonderful activity for adults who have forgotten how satisfying it is to simply investigate something.

You Don't Have to Be a Marine Biologist

The beauty of an intertidal walk is that you don't need to know the names of everything you see.

In fact, don't worry about turning it into a checklist.

You can simply notice:

What is moving?

What is hiding?

What is attached to the rocks?

What is alive?

What has the tide left behind?

Over time, you begin recognising the different shapes and behaviours.

A good pair of eyes is often more useful than a degree in marine biology.

The Tide Is Your Timetable

At Emerald Gecko, the changing tide is quite literally part of the landscape outside your door.

One day you may see the sea almost touching the shoreline.

A few hours later, the water has retreated and revealed a whole new landscape.

Then, gradually, the sea returns.

Please Leave the Tide Pool as You Found It

The creatures living in the intertidal zone are adapted to changing tides — but they are not adapted to being handled by visitors.

So the best rule is simple:

Look, don't touch.

Don't pick up animals for photographs.

Don't remove shells.

Don't turn over rocks and leave them upside down.

Don't collect creatures as souvenirs.

Don't stand on living coral or other marine organisms.

And don't put animals into buckets or containers.

The best tide-pooling experience is one where you leave almost no trace that you were there.

If you gently observe, you can spend a surprising amount of time discovering things without disturbing them.

Be Careful on the Rocks

The intertidal zone can be slippery.

Very slippery.

Wet rocks, algae and uneven surfaces can make walking surprisingly challenging, even when the sea looks calm.

Wear footwear with a good grip, watch where you place your feet and don't venture onto exposed rocks during rough conditions.

A Perfect Slow-Travel Activity

One of the wonderful things about Andaman Islands tourism is that not every memorable experience needs to involve a tour operator or an itinerary.

Sometimes it is simply a matter of being in the right place at the right time.

An intertidal walk is exactly that.

You can spend an hour exploring.

Right Outside Emerald Gecko

Perhaps the nicest thing about tide pooling at Emerald Gecko Resort is its simplicity.

You don't need to get into a vehicle.

You don't need to book a boat.

You don't need to spend the day travelling.

When the tide is right, the intertidal zone is right outside the resort.

Step out.

Walk towards the shoreline.

Slow down.

And start looking.

This is one of the little advantages of staying somewhere that is surrounded by nature rather than separated from it.

At Emerald Gecko, the landscape around you is part of the experience.

The forest.

The beach.

The tides.

The birds.

The rain.

And all the small creatures that quietly get on with their lives while we are busy looking for something more spectacular.

Stay Close to Nature at Emerald Gecko Resort

If you're looking for an eco resort in Havelock Island, a relaxed nature resort in the Andaman Islands, or a base for exploring Havelock Island tourism beyond the usual sightseeing checklist, Emerald Gecko offers something wonderfully simple:

Nature is right outside your door.

And when the tide goes out, another part of the Andaman Islands comes to life.

Come and explore slowly.
