Siju Cave (Bat Cave) in Meghalaya's South Garo Hills is one of India's longest cave systems — a limestone labyrinth of chambers, underground rivers, and million-year-old formations that locals call a portal to the underworld. Home to thousands of bats and the rare Dobsonfly, Siju rewards adventurous travellers willing to wade through waist-deep water with headlamps. Combine with Balpakram National Park or the Garo Hills circuit from Shillong or Guwahati by cab.

About Siju Cave
Formed in limestone karst of the Garo Hills, Siju Cave features the "Princess Di's Chamber" — a stunning stalagmite-stalactite hall — and passages that follow an underground river. The cave opens near the Simsang River, and exploration involves wading through water, climbing boulders, and navigating narrow squeezes. Unlike Meghalaya's tourist-friendly Mawsmai Cave in Cherrapunji, Siju remains raw and adventurous.
The Dobsonfly — one of the world's largest insects — inhabits the cave ecosystem alongside thousands of bats whose droppings (guano) historically fertilised local fields.
