4. Dhanushkodi Island

Dhanushkodi, a forgotten gem at the southernmost tip of Pamban Island in Tamil Nadu, is one of India’s most intriguing and mysterious islands, rich in both history and mythology. Once a bustling town with a railway station, post office, and vibrant market, it was tragically destroyed by a devastating cyclone in 1964, leaving behind only ruins and tales of a once-thriving community. Today, Dhanushkodi is a haunting ghost town, offering an eerie yet captivating glimpse into the past, making it a must-visit destination for those seeking something off the beaten path. The island holds immense significance in Hindu mythology, as it is believed to be the spot where Lord Rama’s army constructed the mythical bridge, Ram Setu (Adam’s Bridge), to rescue his wife, Sita, from Lanka. The name “Dhanushkodi” translates to “tip of the bow,” a direct reference to the epic tale. What makes this island even more special is its natural beauty; pristine beaches stretch for miles, offering a tranquil escape where visitors can enjoy high tides, beachcombing, and even catch a glimpse of magnificent migratory birds like gulls and flamingos. 

The island’s proximity to Sri Lanka, being just 45 meters away, adds to its allure, with the waves crashing against the shores, making it a surfer’s dream. Although it remains largely unknown compared to other famous Indian islands, Dhanushkodi's rugged charm and historical and mythological significance are what make it a hidden paradise. The best time to visit is between October and March, when the weather is perfect for exploring the ruins, visiting the Ram Setu viewpoint, and relaxing on the tranquil beaches.

5. Majuli Island

Majuli Island, located in the heart of the Brahmaputra River in Assam, is the world's largest river island, offering an exceptional blend of culture, history, and nature. Spanning approximately 875 square kilometres, this lush, green paradise is a haven for birdwatchers and cultural enthusiasts. Known for its deep-rooted Assamese neo-Vaishnavite culture, Majuli is home to the famous satras, vibrant monasteries founded by Srimanta Sankardeva, that have preserved the island's rich traditions of dance, drama, and music.

However, despite its natural and cultural wealth, Majuli remains relatively underexplored compared to other exotic Indian islands, mainly due to its limited infrastructure and the ongoing challenge of erosion, which has caused the island’s size to shrink over the years. This makes Majuli not just a hidden gem but a place of urgent importance to preserve for future generations. As it faces environmental threats, it becomes even more vital to visit and experience this unique locale before it’s too late. Easily accessible by ferry from Jorhat, Majuli promises a quiet escape, perfect for those seeking peace, culture, and adventure away from the crowded beaches and well-trodden tourist spots of India. The best time to visit is between November and March when the weather is pleasant and the island's rich flora and fauna are in full bloom.

Everyone living in cities, crowded and congested, swamped with people and dust, will agree when I say Goa is the best place to experience slow living. We constantly hear people referring to the ‘Susegad’ lifestyle, which basically means living a slow and mindful life while being present at the moment. If you want to simply do nothing and unwind in a tranquil space surrounded by groves of coconut trees, fresh air, delicious food and relax, then Goa is your destination. But what if I tell you there’s an unheard-hidden island located just 11 km away from the capital of Panjim that is home to rich flora and fauna? Chorao Island in Goa is truly an unknown destination.
