A group of caves, formerly human settlement, high up on the hills near Mumbai.
The amazing thing about it is, these are not natural caves; rather, man-made: cut and carved deep into the solid rock. A whole village cut into the mountains, with dwellings, schools, temples, water tanks, everything.
The temple hall need to be seen to be believed: High ceiling, with windows for natural light, tall statues carved into the walls, big pillars all around, intricate relief murals.....awesome.
You have to admire the water storage system: big reservoir cut under the floor, only partially visible. High up on the parched hills, with no tree covering, where rain is probably rare, this must have been a life sustaining feat. (Too bad, modern humans seems to see it fit to throw water bottles and plastic bags into it).
If you admire ancient human spirit of survival, outdoor activities like trekking and rock climbing, and panoramic view of the jungle and city from the top,..... don;t miss this!
