Trou aux Cerfs Volcano Review: Hidden Secrets Most Tourists Miss

Explore the Majestic Crater of Trou aux Cerfs – Mauritius’ Iconic Dormant Volcano

Trou aux Cerfs volcano towers 605 meters above sea level in Mauritius, a sleeping giant that last erupted 700,000 years ago but still holds scientific intrigue. With its well-defined cone and crater spanning 350 meters in diameter and plunging 100 meters deep, this cinder cone volcano offers visitors much more than just spectacular panoramic views of the island.

While most tourists capture photos of the small lake nestled at the center of Trou aux Cerfs Mauritius, few learn about its fascinating geological story. Formed less than 2 million years ago during the island’s second phase of volcanic activity, this dormant crater measures more than 984 feet across and represents an important chapter in Mauritius’ natural history. Although scientists believe Trou aux Cerfs has remained dormant for hundreds of thousands of years, experts suggest there’s still potential for it to become active again someday.

Beyond the breathtaking vistas that draw crowds to this Curepipe landmark, Trou aux Cerfs conceals lesser-known features and viewpoints that most visitors overlook. From hidden walking paths to the best times for avoiding tourist crowds, this ancient volcano rewards those willing to explore beyond the main observation deck. The secrets of this geological wonder await travelers ready to venture beyond the typical tourist experience.

What Most Visitors See at Trou aux Cerfs

Most visitors approaching Trou aux Cerfs are immediately struck by its perfectly formed volcanic crater, a massive bowl approximately 350 meters in diameter and about 100 meters deep. Located just 1 kilometer west of central Curepipe, this dormant volcano sits 605 meters above sea level, offering an accessible natural wonder for travelers exploring Mauritius.

Upon arrival, visitors typically follow the well-maintained circular path that extends around the crater’s rim, spanning approximately 1 kilometer in circumference. This paved track has become a favorite spot for both tourists and locals, who frequently use it for jogging and walking exercises. From this vantage point, guests enjoy breathtaking 360-degree panoramic views of Curepipe town and the surrounding landscape.

At the crater’s center, a small natural lake catches the eye, although in recent visits some tourists have reported it appears more like a marshy area sometimes obscured by vegetation. The interior slopes of the crater remain densely covered with lush greenery, creating a stark contrast against the blue Mauritian sky.

One of the most impressive aspects of visiting Trou aux Cerfs is the spectacular vista it provides. On clear days, visitors can see the majestic Rempart Mountain, Trois Mamelles, and the Port-Louis-Mocha mountain range stretching across the horizon. Some locals even claim that when visibility is exceptional, one might glimpse as far as Reunion Island.

Additionally, practical amenities enhance the visitor experience. Three main access points lead to the site: La Hausse de la Louviere Road, Edgar Huges Road, and Crater Lane. Adequate parking facilities make arrival convenient, and a wooden kiosk provides a sheltered spot to relax and appreciate the surroundings.

Interestingly, many visitors notice the radar station positioned at the site, which continuously monitors cyclonic activity in the region—a reminder of nature’s ongoing forces on this tropical island. The area can get surprisingly chilly due to the elevation and surrounding woods, prompting seasoned visitors to bring light sweaters, especially in the afternoon.

Hidden Gems Around Trou aux Cerfs Mauritius

Beyond the main observation areas, Trou aux Cerfs reveals its true magic to those willing to explore deeper. The dense forest surrounding the crater harbors a remarkable ecosystem frequently overlooked by casual visitors. Nature enthusiasts can spot the long-tailed macaque and Mauritian fruit bat (Pteropus niger), the only mammals inhabiting this volcanic habitat.

Early mornings transform the crater into an enchanted landscape as gentle mist envelops the area, creating a mystical atmosphere perfect for photography. This time also coincides with the crater’s popularity among local joggers, who begin their routines around 5:00 AM. Consequently, visitors arriving at this hour experience a more authentic side of Mauritian life.

The forest paths conceal several indigenous plant species, notably the rare Trochetia triflora and Trochetia blackburniana. Furthermore, the endemic manglier (Sideroxylon puberulum) and fanjan trees stand among the more common pine trees (Pinus massoniana). Birdwatchers will appreciate the opportunity to observe:

• The endemic martin (Phedina borbonica) and swiftlet (Aerodramus francicus)
• The vivid red fody (Foudia madagascariensis)
• The endangered Mauritian kestrel and pink pigeon

For photography enthusiasts, the vantage points around the rim offer unmatched opportunities for capturing sunsets over Curepipe and the coastal areas. Unlike other attractions on the island, Trou aux Cerfs remains relatively uncrowded, particularly during weekdays.

The volcano’s tranquil environment has made it increasingly popular for yoga sessions and picnics. Moreover, adventurous visitors can explore the Trou aux Cerfs Walking Path that leads to the summit, offering alternative perspectives of this geological wonder.

Winter months (May to October) provide the best visiting conditions with cooler temperatures and clearer skies, enhancing visibility across the island’s scenic landscapes. During this period, the panoramic views extend to the Mocha Mountain Range and, on exceptionally clear days, parts of the coastline.
