Insider Tip: If you’re a certified diver, don’t miss the opportunity to dive at Barracuda City near Havelock Island. This underwater pinnacle is known for its large schools of barracuda, reef sharks, and vibrant soft corals.
3. Gulf of Mannar
Located between Tamil Nadu and Sri Lanka, the Gulf of Mannar is India’s first Marine Biosphere Reserve and comprises 21 islands with rich coral reef biodiversity.
Highlights:Â Tuticorin group of islands, diving and research experiences
Reef Type:Â Fringing and patch reefs
Marine Life:Â Dugongs (sea cows), sea cucumbers, reef-building corals
Best Time to Visit:Â October to March
The coral reefs in the Gulf of Mannar are mostly fringing and patch reefs, with over 100 species of hard corals and 13 species of seagrasses. The reefs here are not just a visual spectacle but also play a crucial role in the local ecosystem, providing a habitat for countless marine species, including the endangered dugong (sea cow).
To explore the coral reefs of the Gulf of Mannar, head to the Kurusadai and Shingle Islands near Mandapam. These islands offer excellent snorkeling and diving opportunities, with vibrant coral gardens and a chance to spot sea turtles, reef fish, and sea cucumbers.
The best time to visit the Gulf of Mannar for coral reef exploration is between October and March when the waters are calm and visibility is good. The region has a range of accommodation options, from budget-friendly guesthouses to eco-resorts.
Conservation Spotlight: The Gulf of Mannar Marine National Park has implemented several conservation measures, including the establishment of no-fishing zones, the promotion of eco-tourism, and the involvement of local communities in conservation efforts. These measures have helped protect the delicate coral reef ecosystem and the livelihoods of the local fishing communities.
4. Gulf of Kutch
Situated along the northwestern coast of India in the state of Gujarat, the Gulf of Kutch is home to one of the most unique coral reef systems in the country. Unlike the tropical coral reefs found elsewhere, this region hosts cold-water coral reefs, which thrive in comparatively turbid waters and under extreme tidal variations. This makes it an ecological anomaly and an important subject of study for marine researchers.
Highlights:Â Narara Island and Pirotan Island within the Gulf of Kutch Marine National Park offer a one-of-a-kind intertidal coral viewing experience. During low tide, tourists can actually walk on the seabed and observe corals, sponges, and other marine life without diving.
Reef Type: Fringing reefs — these grow close to the shoreline, often forming narrow bands.
Marine Life:Â Hard corals like Porites and Favia, octopuses, jellyfish, sponges, sea anemones, crabs, mudskippers, and dolphins
Best Time to Visit: October to February, when tides are lower and marine life is more accessibleThe coral reef in this region is under protection as part of India’s first Marine National Park, and it supports local livelihoods through eco-tourism and fisheries. Due to the area’s challenging conditions—extreme salinity, sediment influx from rivers, and high temperatures—these underwater coral reefs exhibit a unique resilience not seen in other parts of the country.
The Gulf of Kutch exemplifies how coral reefs can survive and adapt in marginal environments. It is a testament to the diversity of types of coral reefs found in India and is vital to marine biodiversity conservation in the northern Arabian Sea.
5. Malvan
Located along the Konkan coast of Maharashtra, Malvan is emerging as a promising coral reef destination, especially for travelers looking for a convenient coastal getaway combined with marine adventure. Though smaller in scale compared to the reefs of Lakshadweep or the Andamans, the coral reef in Malvan offers accessibility, affordability, and beginner-friendly dive experiences.

Marine Life:Â Soft corals, sea urchins, clownfish, butterflyfish, sea cucumbers, and vibrant reef flora
Best Time to Visit:Â October to March, when water clarity is optimal and tourist activities are in full swing
While Malvan’s reefs are relatively new and developing, conservation programs by the Maharashtra government and marine research institutions are helping protect these coral ecosystems. The reefs are now part of marine biodiversity awareness initiatives, attracting students, researchers, and eco-tourists alike.
Malvan stands as a prime example of how local coastal regions can cultivate coral reef tourism with the right ecological management. The underwater coral reef experience here is ideal for families, amateur divers, and anyone who wants to witness coral islands and marine beauty without venturing too far from the mainland.
