Reach the caves via a scenic mangrove boat ride through Baratang's waterways
Most visitors to the Andamans stick to the southern islands, Havelock, Neil, Port Blair. But the real adventure seekers, the ones who do not mind an early start and a long day, they head north to Baratang Island. The limestone caves here are unlike anything else in the Andamans, not a beach, not a reef, but a natural underground formation shaped by water dripping through rock over millions of years. Getting there is half the story, a drive through dense forest, a creek crossing by small ferry, a speedboat ride through mangrove-lined waterways. The caves themselves are not massive, you are not walking for miles underground, but what they lack in size they make up for in strangeness, stalactites hanging from the ceiling, stalagmites rising from the floor, all of it glowing in the light of the guides' torches. It is a full day trip from Port Blair, a long one, but the kind of day that stays with you.
The limestone caves are located on Baratang Island, about 100 kilometres north of Port Blair. The journey from Port Blair takes roughly three to four hours each way, depending on road conditions, ferry queues, and the speed of your vehicle. The caves themselves are part of a larger limestone deposit that runs through this section of the Andaman archipelago, formed over millennia as acidic water dissolved the soft limestone rock, leaving behind hollow chambers and the distinctive dripstone formations.
The main cave is not huge, maybe a hundred metres or so of accessible path, but it is packed with formations. Stalactites hang from the ceiling like icicles made of stone. Stalagmites rise from the floor where drips have landed and built up over thousands of years. Some of them have grown together to form columns. The rock itself is a pale grey-white, but the guides shine their torches at different angles, and suddenly the walls look golden, then brown, then almost translucent in spots.
The caves are protected, which means you cannot go in without a guide, and you cannot touch the formations. The oils from your skin damage the rock and stop the growth process. But you can walk through, look up, look down, and marvel at the fact that these shapes were not carved by any human hand, just water, time, and a little bit of luck.
The limestone caves on Baratang have been here for millions of years, long before humans ever set foot on these islands. The limestone itself started as coral reefs and marine organisms, compressed over eons into solid rock. When the islands rose out of the sea, the rock was exposed to rainwater, which is slightly acidic, and over time, that acid dissolved passages and chambers into the soft limestone.
For most of history, the caves were known only to the local indigenous tribes, particularly the Jarawa, who live in the forests that you drive through to reach Baratang. The caves were not discovered by outsiders until the late 20th century, and they only became a tourist attraction in the last twenty years or so.
The journey to Baratang passes through what is known as the Jarawa Reserve, a protected area where the Jarawa tribe lives in voluntary isolation. The Andaman administration strictly regulates the route, and vehicles are not allowed to stop, interact with, or photograph the Jarawa people. It is a sensitive area, and visitors are expected to follow the rules without exception.
Today, the limestone caves are one of the most popular day trips from Port Blair for travellers who have already seen the southern beaches. The infrastructure is basic, a few shops near the cave entrance sell water and snacks, and local guides lead groups through the formations. But the caves themselves remain wild and untouched, a reminder of how old this land really is.
Plan Your Limestone Caves Visit with Our Local ExpertsThe limestone caves are the destination, but the journey is just as memorable. Here is what to expect during your day trip from Port Blair.
The cave walk is short, maybe fifteen to twenty minutes from entrance to exit, but you will want to go slow. The stalactites hang down from the ceiling in clusters, some thin as pencils, others thick as tree trunks. Water drips constantly, the sound echoing off the stone walls. The stalagmites rise up from the floor, some reaching waist-high, others still just small bumps that will take another thousand years to grow. Your guide will point out the shapes, here a face, there an animal, the usual cave tour stuff, but the real pleasure is just looking at the raw geology. The rock is soft enough that you can scratch it with a fingernail, though you should not. And the light, bouncing off the wet surfaces, makes the whole place glow.
Before you reach the caves, you take a speedboat through a narrow mangrove creek. This is not a small part of the trip, it is a highlight on its own. The creek is lined with mangrove trees, their roots dipping into the dark water like twisted fingers. The boat moves fast, the wind in your face, the driver weaving between the trees. Kingfishers flash blue and orange along the banks. Mudskippers, those strange fish that walk on land, sit on exposed roots. The whole thing feels like a scene from a nature documentary, and it lasts maybe fifteen minutes, but it is the kind of fifteen minutes you will remember long after the caves have faded.
The road from Port Blair to Baratang passes through the Jarawa Reserve, a protected forest area home to the Jarawa tribe. The rules are strict, you cannot stop, you cannot get out of the vehicle, you cannot take photos or videos. The road itself is a narrow strip of asphalt cutting through dense tropical forest, with signs on both sides warning visitors not to interact with the tribe. Sometimes you see them, sometimes you do not. If you do, you keep driving, you do not stare, and you definitely do not take pictures. It feels strange, driving through someone else's homeland like a visitor in a zoo, but the rules exist to protect the Jarawa, and breaking them is both illegal and unethical. Follow the rules, no exceptions.
Most limestone cave trips from Port Blair also include a stop at the mud volcanoes, a short drive from the jetty on Baratang Island. These are not volcanoes in the usual sense, no lava, no fire. Instead, cold mud bubbles up from underground, pushed by natural gases, and pools in shallow craters. The mud is grey and thick, and it makes a soft plopping sound as bubbles rise to the surface. It is a quick stop, fifteen minutes at most, but the sight of mud bubbling out of the ground like a pot of cold porridge is strange enough to be worth the detour. Local legend says the mud has medicinal properties, though no one has proven it.

Start early, very early. The road from Port Blair to Baratang gets busy, and the ferry crossing at the Jarawa Creek has a long queue if you arrive late. Most tours leave Port Blair around 4:00 or 4:30 AM, which sounds brutal but makes sense once you see the line of vehicles waiting at the crossing. The early start also means you avoid the worst of the midday heat when you are walking through the forest to the caves.
Wear shoes with good grip. The path to the caves is uneven, muddy in places, and the cave floor can be slippery from the constant drip of water. Flip-flops are a bad idea. Also wear clothes you do not mind getting dusty or damp, the cave is humid, and the walk involves some crouching in spots.
Carry water, snacks, insect repellent, and toilet paper. The facilities at the cave entrance are basic at best, and there is nowhere to buy food or water once you are past the jetty. The trip is long, and you will be hungry and thirsty by the time you finish the caves. A packed breakfast and lunch are a good idea, something simple like sandwiches and fruit.
Do not touch the cave formations. The guides will tell you this at the entrance, but it bears repeating. The oil on your fingers stops the stalactites and stalagmites from growing, and it takes thousands of years for them to recover. Also, follow the rules in the Jarawa Reserve. Do not stop the vehicle, do not get out, do not take photos, do not offer food or gifts to anyone you see. The rules are there for a reason, and breaking them puts both you and the Jarawa people at risk.
The limestone caves at Baratang are not for everyone. If you want a relaxed beach holiday, skip them. But if you have a spare day in Port Blair, if you are curious about what lies north of the tourist trail, and if you do not mind an early start and a long drive, the caves are worth the effort. The formations are impressive, the mangrove creek ride is unforgettable, and the whole experience feels like a real adventure, the kind that does not involve a beach chair or a cocktail.
