Located at the foot of a cliff in Raigad, roughly three hours from Mumbai, are a bunch of 23 Buddhist caves considered one of the oldest rock-cut temples of India. Until 5 AD, the Thanale caves were part of a trade route that snaked inland from the ancient port of Chaul, a Portuguese city near Mumbai. When the route changed, the caves were abandoned only to be rediscovered in 1890. If you're keen to explore these stone chambers, sign up for a day trek with Jungle Lore.
