When you close your eyes and think of Mauritius you probably picture white sand, turquoise water, and a cocktail with a little umbrella in it. Mari top! (That is awesome!) We love that version of the island too. But if you turn your back on the ocean and look inland you will find a completely different world.
Welcome to Plaine des Roches.
This is not a place for sunbathing. This is a place for adventuring. Located in the north eastern part of the island, straddling the districts of Rivière du Rempart and Flacq, this village is the geological backbone of our country. It is rugged. It is rocky. It is absolutely fascinating.
While the rest of the world knows us for our beaches, geology nerds know us for Plaine des Roches. It offers a stark contrast to the coastal resorts. Here the ground tells a story of fire and lava that happened 25,000 years ago. It is a quiet and rural community defined by its rocky terrain and vast sugar cane fields. More recently it has become famous for its pivot toward renewable energy.
For the traveler who wants to see more than just the hotel pool, Plaine des Roches is an unmissable stop. It is famous for its subterranean lava tubes and the island’s first wind farm. It offers a glimpse into both the ancient geological history and the modern sustainable future of Mauritius.
So tie your shoelaces tight. We are going off the beaten path. Allez! (Let’s go!)

The Story in the Stone: History and Origins
The name “Plaine des Roches” literally translates to “Plain of Rocks” in English. Whoever named it was definitely not trying to be poetic. They were being accurate. The landscape is scattered with thousands of basalt rocks.
These rocks are not just random debris. They are the remnants of volcanic activity from what geologists call the “Recent Series” of eruptions. In geological terms, 25,000 years ago is practically yesterday. It means the ground you are walking on is relatively young compared to the older mountain ranges in the south.
A Landscape Shaped by Hands
Historically the area was dominated by agriculture. Specifically sugar cane and tobacco thrived here despite the difficult soil. If you look at the fields you will see piles of rocks stacked neatly in pyramids or walls. These were not placed there by nature.
They are a testament to the immense labor of the region’s indentured laborers and early farmers. They had to clear these rocks by hand to reach the fertile soil underneath. Every time you see a clear patch of green cane in Plaine des Roches remember that someone moved the volcanic stones one by one. It gives you a new appreciation for the history of the island.
The Airport That Never Was
Here is a fun fact that you can use to impress your friends at dinner. After World War II the government was looking for a place to build a new airport. The topography of Plaine des Roches is very flat which made it a top candidate.
Imagine if they had gone through with it. Instead of flying into Plaisance in the south you would be landing right here among the lava rocks. However the project never materialized. The region remained agricultural and quiet. We think it is for the best. The peace and quiet of the lava fields would be ruined by jet engines.
Entering the Modern Era
In 2016 the village entered the history books again. It became the home of the Plaine des Roches Wind Farm. This was the first utility scale wind power project in Mauritius. It marked a huge shift for the area. It went from traditional agriculture to cutting edge green energy. Now the ancient rocks sit in the shadow of modern turbines. It is a beautiful contrast.
Geography and Demographics
Plaine des Roches is a bit of a puzzle when it comes to maps. While it functions as a single Village Council Area it is geographically split between two districts.
The Northern part belongs to the Rivière du Rempart District. This is where the majority of the population resides. The Southern part falls under the Flacq District.
Despite this administrative split the community is tight knit. The population is approximately 4,000 residents based on older census data so it has likely grown to around 4,500 by now. The economy is still deeply rooted in agriculture. You will see farmers tending to vegetables and sugar cane all day long. However the wind farm operations and small scale commerce have brought new jobs to the area.
What to See and Do: Key Attractions
You do not come here for shopping malls or cinemas. You come here to see nature in its rawest form. Plaine des Roches is best known for two major landmarks that sit at opposite ends of the timeline. You have the ancient lava caves and the modern wind turbines.
1. Roches Noires Lava Tubes
Google Map: Get Directions to the Caves
This is the main event. The area is home to a network of interconnected volcanic caves formed by cooling lava flows. When the surface of the lava flow cooled and hardened the molten lava inside kept flowing. When the eruption stopped it left behind these hollow tubes.
The most famous entry point is known as the Princess Margaret Cave.
- Freshwater Pools: One of the coolest things about these caves is the water. Underground springs flow through them creating freshwater pools. The water is crystal clear and very cold.
- Cool Temperatures: Walking into the cave feels like walking into an air conditioned room. It is a refreshing break from the tropical heat outside.
- Geological Formations: You can see the ripples in the rock where the lava once flowed. It is frozen in time.
Exploration Tip: The lava tubes are fascinating but they are also wild. While some entrances are accessible to the public they are unlit and rugged.
- Safety First: Do not attempt to go deep into the caves without a guide or proper gear. The ground is uneven and slippery. If you are unsure about safety in remote areas check our article Is Mauritius Safe? An Honest Guide.
- Light: Phone flashlights are insufficient. The darkness inside eats up weak light. Bring a powerful headlamp so you can keep your hands free for balance.
- Wildlife: Look up to see the swiftlets nesting on the cave ceilings.
2. Plaine des Roches Wind Farm

You cannot miss these. Literally. They are gigantic. The wind farm is operated by Qair (formerly Quadran) and consists of 11 towering turbines. These are Gamesa G58 models if you are into engineering specs.
They dominate the skyline of the east. Seeing them up close is a surreal experience. They make a rhythmic swooshing sound as the blades cut through the air.
- Photography: This is a photographer’s dream. The contrast of the white sleek turbines against the lush green cane fields and the black volcanic rock makes for striking photos. It is the perfect blend of nature and technology.
- Sunset: If you can time your visit for late afternoon the light hitting the turbines is magical.
3. Nature and Wildlife
The area is not just rocks and metal. It is a habitat for some rare endemic species.
- Mascarene Swiftlet: These are often mistaken for bats because they fly erratically and nest in caves. But they are actually birds. They navigate the dark lava tubes with incredible skill.
- Blue Tailed Day Gecko: Keep your eyes on the basalt rocks. You might spot these colorful little guys sunning themselves. They are bright green with red spots and a blue tail. Mari joli (Very pretty).

Visitor’s Guide: How to Visit
Plaine des Roches is rural. That means you cannot just snap your fingers and appear there. You need a plan. It is located roughly 10 to 15 minutes inland from the coastal village of Roches Noires.
By Car
This is the easiest way to explore. It gives you the freedom to stop for photos whenever you want. If you are renting a vehicle make sure to read our guide on Buying and Registering a Car in Mauritius which has some handy driving tips for visitors too.

- From Flacq: Head north along the coastal road. Turn inland at Roches Noires or Poste de Flacq.
By Bus
For the budget travelers and the adventurous souls the bus is a great option. It takes longer but you get to see local life up close.
- Route 28: This bus runs from Rivière du Rempart to Plaine des Roches (Terminus). This is your most direct line.
- Route 221 or 222: These connect Rivière du Rempart to Central Flacq. They pass through nearby villages. You might have to transfer or walk a bit.
We always recommend checking the specific schedules before you go. You can find more details in our Mauritius Bus Guide.
Dining: Where to Eat
Since Plaine des Roches is a rural village you will not find fancy fine dining restaurants with white tablecloths. And honestly that is a good thing. You want real food.
Dil Se Ltd: Get Directions
This is a local gem in the area. It is known for serving authentic Mauritian cuisine. It offers a genuine “table d’hôte” style experience compared to the tourist heavy spots on the coast. You can expect curries and faratas and rougail that taste like they were made in a grandmother’s kitchen.

What to Wear and Bring
This is not a flip flop destination. Ayo please do not wear flip flops here. The volcanic rock is sharp and unforgiving. One slip and your toes will be very unhappy.
- Footwear: Sturdy hiking boots or good sports shoes are non negotiable if you plan to visit the caves or walk near the wind farm.
- Clothing: Wear light and breathable fabrics. It gets hot in the cane fields. However if you are entering the caves be aware it can be cooler and damp inside.
- Essentials: Mosquito repellent is a must. They love the cane fields. Bring plenty of water as there are no shops near the caves. And bring a high lumen torch for the caves.
