Common questions

What exactly is the Underwater Waterfall in Mauritius?

The Underwater Waterfall in Mauritius is not a true waterfall but an optical illusion created by the movement of sand and silt deposits under ocean currents. This phenomenon occurs off the southwestern coast of the island near Le Morne Brabant. The illusion is best observed from above, making aerial views particularly stunning. The varying colors of the ocean waters, ranging from turquoise to deep blue, enhance the effect and make it appear as though there is a waterfall plunging into the ocean depths.

How is the Underwater Waterfall illusion created?

The illusion of the Underwater Waterfall is created by the movement of underwater currents that carry sand and silt downwards along the ocean floor. This happens at the edge of the ocean shelf near Mauritius where the seabed suddenly drops off into much deeper ocean waters. The sediment movement coupled with the color gradients of the shallow and deep waters reflect light in a way that simulates the appearance of a waterfall. This interesting visual effect is most prominent from an aerial perspective.

What is the best way to view the Underwater Waterfall?

The best way to view the Underwater Waterfall is from the air through a helicopter tour. This provides a direct and unobstructed view of the illusion from above, and you can truly appreciate the dramatic contrast in ocean colors. Helicopter tours typically depart from various locations in Mauritius, offering different packages that may include commentary about the natural phenomenon and surrounding geography.

What are some attractions near the Underwater Waterfall?

  • Le Morne Brabant: Nearby the underwater waterfall, this UNESCO World Heritage site offers hiking opportunities with panoramic views.
  • Chamarel Coloured Earths: Located a bit north, this is a natural phenomenon showcasing sands of seven distinct colors.
  • Black River Gorges National Park: Perfect for nature enthusiasts, this park features dense forests, waterfalls, and hiking trails.
  • La Vanille Nature Park: Ideal for families, the park homes giant tortoises, crocodiles, and other wildlife.

These attractions offer a rich experience combining nature, adventure, and cultural history.

What is the best time of year to visit the Underwater Waterfall?

The best time of year to visit the Underwater Waterfall in Mauritius for best visibility of the illusion is during the summer months from September to March. During this period, the weather is usually clearer with less rainfall, providing better conditions for helicopter tours and clearer aerial views. However, it’s important to check the weather in advance as conditions can vary.

Can you swim near the Underwater Waterfall?

No, swimming near the Underwater Waterfall is not recommended nor is it particularly feasible, given the illusion is best observed from an aerial viewpoint. The area consists of deep ocean waters and strong currents which can be dangerous. For swimming, snorkeling, and diving, there are other safer and more suitable locations around the island of Mauritius.

Are there any conservation efforts related to the Underwater Waterfall region?

The Mauritian government and various environmental organizations work together to protect the marine environment, including the coral reefs surrounding Le Morne, which contribute to the clarity and the stunning natural beauty seen in the area. Efforts include regulations on marine traffic and strict guidelines for aerial tourism operators to minimize environmental impact.

These waters are also home to colorful corals and other sea creatures like starfish and sea urchins, making it a vibrant ecosystem.

What photography tips are recommended for capturing the Underwater Waterfall?

When trying to photograph the Underwater Waterfall, consider the following tips:

  • Time of Day: Early morning or late afternoon are usually best for aerial photography to avoid harsh midday light.
  • Camera Settings: Use a polarizing filter to reduce glare from the water and enhance the colors of the illusion.
  • Window Removal: Some helicopter tours offer the option to remove the window for clearer shots.
  • Stability: Use faster shutter speeds to counteract the vibration of the helicopter.

Capturing the right angle and conditions can dramatically enhance the dramatic visual impact of the underwater waterfall.

How has global warming affected the Underwater Waterfall area?

Global warming poses a threat to the delicate ecosystem around the Underwater Waterfall area, primarily impacting the coral reefs through bleaching, which occurs when corals lose their vibrant colors due to stress factors such as increased water temperatures. The phenomenon can also influence sea levels and subsequently alter the coastal areas and underwater structures on the seabed. Additionally, changes in ocean currents can potentially influence the very sediment transport patterns that create the illusion of the underwater waterfall, altering its visibility and appearance.

Are there any local cultural or historical features to explore in the area surrounding the Underwater Waterfall?

The area surrounding the Underwater Waterfall, especially near Le Morne Brabant, is rich in cultural and historical significance. Le Morne itself is a symbol of the struggle for freedom, where runaway slaves used to hide in the 18th and early 19th centuries, and it is recognized as a UNESCO World Heritage site. Visitors can explore the local culture through guided tours that explain the history as well as by visiting local villages where traditional Mauritian lifestyles can still be observed. It’s an enriching experience that parallels the natural beauty of the site.

Is the underwater waterfall in le morne worth visiting?

The Underwater Waterfall in Le Morne is not an actual waterfall but a stunning visual illusion created by sand and silt deposits. This phenomenon, while brilliant when viewed from above, particularly via drone or aerial photography, may not offer the same spectacle up close on a boat or from the shore. It’s an extraordinary site for photographers and nature lovers who appreciate unique natural occurrences. However, for travelers seeking thrilling physical experiences or actual underwater adventures, this might not meet their expectations. The illusion predominantly relies on specific viewing angles and light conditions. Thus, while it’s worth a visit for its uniqueness, it might not satisfy every type of tourist.
