The Labyrinth Below: Belum Caves, Andhra Pradesh
Welcome to the second-largest cave system on the Indian subcontinent. Stretching over 3.2 kilometres, the Belum Caves are a geological marvel. Unlike the damp, tight squeezes you might imagine, Belum offers vast, cavernous chambers and long, winding passages
formed in black limestone. The adventure here is one of scale. As you walk through the illuminated pathways, you’ll encounter stunning freshwater galleries, siphon tunnels where water once gushed, and colossal chambers that make you feel like you’ve stepped onto another planet. One section, the 'Patalaganga', is a perennial stream that disappears into the depths of the earth. While partially developed for tourism, its sheer size and the echoes in its silent, deep chambers provide a profound sense of exploring a lost world.
The King of Caves: Krem Liat Prah, Meghalaya
For the hardcore spelunker, Meghalaya is the ultimate playground, and Krem Liat Prah is its crown jewel. As one of the longest sandstone caves in the world, its mapped length is a staggering 30+ kilometres and still growing as explorations continue. This is not a casual stroll. Venturing into its network requires a guide, proper gear, and a good level of fitness. The reward? A raw, untamed caving experience through the ‘Cave of the River of Evil’. You'll wade through underground streams, marvel at vast calcite formations in the ‘Aircraft Hangar’ chamber, and navigate a complex maze that few have seen. This is adventure in its purest form—a true expedition into the planet’s dark, unchartered corners.
The Dazzling Spectacle: Borra Caves, Andhra Pradesh
If your sense of adventure is sparked by natural beauty, the Borra Caves are unmissable. Located in the Ananthagiri hills of the Araku Valley, these caves are famous for their spectacular speleothems—the countless stalactites and stalagmites that have formed over millions of years. This is nature’s art gallery. Light and shadow play across karstic limestone formations that have been given names based on their shapes, such as ‘Shiva-Parvati’, ‘Mother-Child’, and ‘Human Brain’. The adventure here is visual and geological. The caves are considered the deepest in India, plunging down 80 metres. While well-lit and accessible, the sheer variety and density of the formations, coupled with the Gosthani River flowing through the caves, create an otherworldly atmosphere that feels both ancient and alive.
The Accessible Thrill: Mawsmai Cave, Meghalaya
Not ready to commit to a multi-day expedition? Mawsmai Cave, near Cherrapunji, offers the perfect taste of Meghalayan caving in a safe and accessible package. It's one of the few caves in the region that is fully lit, allowing you to appreciate the intricate details of the rock formations without needing a headlamp. But don't mistake accessibility for a lack of adventure. The cave is a maze of chambers and passages, some of which require you to squat and squeeze through. As you navigate the limestone path, you’ll see water dripping from the ceiling, forming tiny stalactites and creating a dynamic, living environment. It’s the ideal introduction to the thrill of caving—a short, concentrated dose of subterranean wonder that will leave you wanting to explore more.
