Anthara Gange Caves

Anthara Gange sits on the same hill range as Nandi Hills and Skandagiri, but the draw here is entirely underground — a series of narrow rock passages and caves you crawl and squeeze through, some barely shoulder-width, leading to a small spring that's considered sacred and, according to local belief, connected underground to the Ganga.

A local guide is genuinely worth hiring, both because the cave layout is confusing and because they know which passages are safe in current conditions. This is a scramble-and-crawl experience more than a walk, so it's not suited to anyone with claustrophobia or mobility limitations.
