An Adventure With Our Volcanoes...

Mauritius, a Mascarene island in the Indian Ocean, with a latitude of -20° 12' 23.94" S and longitude of 57° 40' 31.80" E, was formed around 10 million years ago, by an undersea volcano. The beautiful mountains and hills englobed with their basalt rocks and soil present in every district are all originated from gigantic lava flows. Even several thousands of years have passed since the last volcanic activities, few volcanic craters and cones have remained as footprints, which this article will make you discover.

ATTENTION: This is a discovery article rather than a scientific one. The purpose of this article is to make people discover the popular craters we have on our island.

A Quick Overview On Volcanic Cones With Crater & Without Crater

You will be surprised after believing, our small island is composed of more than 20 volcanic craters and cones without craters. The mountains and hills you see around are examples of volcanic cones. In the world of volcanology, there are different cones, such as stratocone, spatter cone, tuff cone, conder cone, and rootless cone.

Volcanic cones often have a crater. A crater is normally a circular hole in the ground of the cone, formed due to volcanic activity. A crater can be empty, filled with snow, constitutes vegetation, and finally, filled with a lake. As you probably know, most of the volcanic craters in Mauritius include dense vegetation or a lake.

There are volcanic cones that do not have a crater. They just look like a hill, covered with trees. You may not differentiate them from mountains or hills, because they can look the same.

Trou Aux Cerfs

Situated around 605m above sea level in the district of Plaine Wilhems, precisely in the marvelous town of Curepipe, the Trou Aux Cerfs is the most popular volcano on our island. In the early 1800s, Trou Aux Cerfs was commonly written as “Tronc Aux Cerfs” on some documents. According to some reports, they described how the deers were wandering inside the crater, thus, the name was derived from it.

It is classified as a dormant volcano, constitutes a crater lake, and is surrounded by dense shrubs and trees. The diameter of the crater is approximately 350m and the central depression’s depth is about 85m. Decades ago, there were vineyards and plantations in the crater, managed by the Botanist Lavignac. He even wanted to build his house inside.

Nowadays, lots of joggers and enthusiasts frequent the place, which has made it great for sightseeing, particularly for tourists. The tracks to descend to the crater are not that easy. One of them is extremely complicated due to the dense shrubs and trees. The other common track is slippery in rainy weather, hence, muddy and still surrounded by thorny bushes. Some people fish in the lake. The vineyards do not exist anymore, but some ruins have remained, and the crater has been abandoned like a deep pit full of mosquitoes and giant rats, without forgetting the monkeys. However, it does have a fantastic flora and fauna. The video below depicts the remained vineyard's ruins and the crater:

Bassin Blanc

The La Marie road which leads to Mare Aux Vacoas reservoir is calm and you usually feel a cold wave, particularly when driving. Continuing the road, it passes by Plaine Sophie Nature Walk and goes to Pétrin. Ahead, there is a small roundabout, on the right that leads to the splendid village of Chamarel, but if you continue straight, you will descend to Mont Blanc, after encountering several narrow zigzag turns, to reach the mysterious crater lake of Bassin Blanc.

A mysterious crater lake because, it has a reputation for being a spooky, dark, and dangerous place. Several people's corpses have been recovered there, which were involved in murders and suicides. One of the famous cases was in 2002, two people were recovered from the lake, tied to each other, which has caused controversies on the real cause of death, whether it was a suicide or murder.

Bassin Blanc’s last eruption was 20,000 years ago and is classified as an extinct volcano. It is situated 450m above sea-level approximately. It is surrounded by a thick forest and the exact depth of the crater lake is still unknown. Some scholars say around 20m deep, however, no exact figure is known. The track to descend to the crater is extremely tricky, where one can get easily lost. When you reach the edge of the cone, you can see from the top the immense amount of trees at the bottom. To reach the lake, there is a high possibility to walk in thick mud, depending on the weather, challenging the dense bushes, and end to the lake. Verily, the atmosphere at the bottom is creepy, similar to in a horror movie. This is not a place to wonder if you have a chicken heart!

Trou Kanaka

Further away from Grand Bassin, in the direction of Avalon on the road to Bois Chéri, situates the Trou Kanaka crater. The Kanaka crater was lesser-known until, a few years, its popularity to discover has grown.

The crater lake is originated from an extinct volcano, 700,000 years old. It does not require much effort to descend into it, even it is a bit slippery. The marshy lake is full of vegetation, so thick that you can jump on it in some areas. Around the crater, there are vast tea plantations. The atmosphere is cold, tranquil, and amazing to be if you want to disconnect from the usual busy life.

Grand Bassin

Some kilometers away from Bassin Blanc, precisely on the road to Pétrin, the right leads to the sacred lake of Grand Bassin. Grand Bassin, also known as Ganga Talao, is a crater lake from an extinct volcano, located 560m above sea level. The weather in the region is most of the time rainy, foggy and cloudy.

It is considered a sacred lake by the Hindu community, who every year goes to pilgrimage there on the occasion of Maha Shivratee religious festival. The first pilgrimage began at the end of the 19th century and has been going on until today. Grand Bassin’s first name was Pari Talao, and later changed in the 1970s to Ganga Talao.

Around the lake, there are spots for devotees to pray. On the other side, there are dense trees and private lands. There is even a small islet in the middle of the lake. It is believed the exact depth of Grand Bassin is unfathomable, nevertheless, Allistair Macmillan cited in his book: Mauritius Illustrated: Historical and Descriptive; Commercial and Industrial; Facts, Figures and Resources, published in 1914, probably the lake is 16m deep. Grand Bassin was first appeared on the map of Jacques Nicholas Belin, in 1753.

Bar Le Duc

Far from the district of Plaine Wilhems and Savanne, where the majority of the famous craters situate, there is a small village called Bar Le Duc. It is located near Nouvelle Découverte, on a hill, and the crater is on a private property where permission is needed to access.

Bar Le Duc is a young crater, 20,000 years ago since its last activity. Surrounded by some native plants and shrubs, it is believed that Bar Le Duc is the smallest crater in Mauritius. Nearby the region, there are various caves originated from different lava flows.

Some lesser-known craters in Mauritius are described in brief, as follows:


Mont Piton

Mont Piton is the highest hill in the North, with approximately, 260m in height. The crater is located where a small forest can be seen from the surroundings.

Butte Aux Papayes Hill

Situated in the North, near Belle Vue Harel, the Butte Aux Papayes Hill’s elevation is around 145m. It was a volcano and today, there is the "Domaine de Hillside".

Forbach Hill

A bit ahead of Butte Aux Papayes situates another extinct volcano, the Forbach Hill. The elevation is low. The hill is composed of sugarcane fields.


The Mount Hill

The Mount is situated close to Piton Crater. The elevation of the hill is low, less than 100m, and is full of sugarcane fields.

Mon Loisir Hill

Another Natural Beauty Facets...

We are fortunate our island is enriched with natural beauties. Mauritius is reputed for its fantastic beaches and breathtaking mountains or waterfalls, but there are unpopular natural facets that are still yet to be discovered. Our remaining craters are great examples! We have a strong geological part and our country's formation itself is based on it. Hopefully, this short article has enabled you to discover a little about our volcanoes.
