One-way route — ascend only: Nalichi Vaat is climbed, not descended. Getting down it is considerably harder than getting up, and the two rock patches are the reason. Plan to leave the Harishchandragad plateau by another route.
Skip decision — take it before you enter the gully: with solid experience on boulders and in gullies, and basic rock climbing, this goes without ropes. There are two rock patches where a fall would be fatal — you cannot afford a slip on either. The first patch is 15 ft inside the gully, with enough holds but a moderate climbing move; a scree section needs real footwork rather than climbing; the second patch, just before the final climb, is a wall close to 70° and again around 15 ft; and a short section above that has rock that is not solid — it can come away under pressure, so test before you weight it. Not for beginners, and not for anyone with acrophobia. There is no cellular network anywhere in this gully, and it is remote.
Watch out: climb Nalichi Vaat with a companion, so that one person can top out the first rock patch and stand up to spot holds for the other from above. A sudden whooshing blast a bird makes when flying fast through a narrow gully can feel like a falling stone right on your head, and on a rock face that reaction can cost you your focus at exactly the wrong moment. Birds and monkeys moving above you can also send small stones down — stay alert, stay steady, and keep checking what is above you.
