Travel to Belum Caves: A First-Timer’s Guide to India’s Longest Show Cave
The longest cave system open to visitors in India — a lit underground network of passages, chambers and stalactites carved by an ancient river beneath the Rayalaseema plains.
The Belum Caves, in the Kurnool district of Andhra Pradesh, are the longest cave system open to the public in India — a vast, lit underground network of tunnels, chambers and formations carved over millennia by an underground river. Descending from the flat Rayalaseema plains into a cool, echoing world of stalactites and stalagmites is a genuinely surprising experience, and one still relatively few travellers make. Compact enough to see in a few hours, Belum pairs perfectly with the nearby Gandikota canyon for a memorable off-beat weekend.
Why visit Belum Caves
India’s longest show cave
Belum is the longest cave system open to visitors in the country — over a kilometre of accessible passages — making it a rare and impressive underground adventure.
Formations and chambers
Inside are dramatic stalactite and stalagmite formations, deep sinkholes, and named chambers — some with fanciful shapes — all atmospherically lit.
Easy to pair with Gandikota
Belum sits within easy reach of the Gandikota gorge, so the two combine naturally into one of Andhra’s best off-beat weekends.
When to go to Belum Caves
October to February is the best time to visit, when the surface heat is bearable — though the caves themselves stay cool year-round. Rayalaseema summers (March to June) are extremely hot above ground, making the journey uncomfortable even if the caves are pleasant. Aim to visit earlier in the day, and note it can get warm and humid deep inside despite the ventilation.
Top things to do in Belum Caves
Descend into the main caveDo not miss
The heart of the experience: following the lit walkways down into the earth through a series of passages and chambers, past stalactites and stalagmites, in India’s longest accessible cave.
The named chambersDo not miss
Belum’s passages open into named halls — like the meditation hall (said to have been used by monks), the “thousand hoods” formation and the musical chamber — each with its own character.
Patalaganga & the deepest point
Deep inside flows Patalaganga, a perennial underground stream, near the lowest accessible point of the cave — the atmospheric climax of the walk.
The Buddha statue & entrance park
Above ground, a large Buddha statue and a small park mark the site (Belum has ancient Buddhist and Jain associations), a pleasant spot before or after your descent.
Combine with Gandikota
About 65 km away, the Gandikota gorge — the “Grand Canyon of India” — is the natural companion to Belum for a canyon-and-caves trip.
Yaganti & nearby temples
The cave temple of Yaganti, famed for its growing Nandi, and other Rayalaseema sights lie within reach for those making a longer regional loop.
What to eat around Belum Caves
Carry supplies
Facilities at Belum are limited, so carry water and snacks; there are basic stalls near the entrance.
Rayalaseema meals
The region’s fiery cuisine — ragi sangati and spicy curries — can be found in nearby towns like Tadipatri.
Dhabas & tiffin

Eat before/after
Plan meals in Tadipatri, Gandikota or on the road rather than at the caves themselves.

Practical tips that actually help
Visit October to February and earlier in the day to avoid the surface heat. Wear comfortable shoes with grip — there are stairs and some low, narrow sections — and be ready for warm, humid air deep inside. Carry water. Pair Belum with Gandikota to make the journey worthwhile. And allow around a couple of hours for the full underground circuit.
Mistakes first-time visitors make
Coming in peak summer, when the surface journey is punishing. Rushing the cave circuit — give it a couple of hours. Wearing slippery footwear on the ramps and stairs. Expecting food and facilities at the site itself. And making the long trip for the caves alone rather than pairing them with Gandikota.
