There is a dead end path forking of the path (the one running south south east to north north west. I could provide track information on request.

There is a barrier gate here and the road leading north west is not open to the public.

Stairs down to the waterfall start here. The location of the waterfall itself is rather at 20.741692, 105.054628.

At this place there are hot springs. A nice little place. Please add it. On Google Maps it is called "Suối Nước Nóng Bò Ấm".

This is not the place where tickets are sold, it is the place where one boards the boats. The ticket office is at 20.216957486795298, 105.94037961738788 (however I am not 100% sure that I got that location right)

At least in maps.me it looks like as if the ticket office of the Van Long Wetland nature reserve was at this spot. It is not. The correct location is at 20.362143699171686, 105.88245311620757. The place of the ticket office should definitely be added to OSM.

There is no view from this point. Furthermore it is a bit dangerous to get there.

They have moved to 41 Trần Hưng Đạo, Phường Minh An, Hội An, Quảng Nam. See https://maps.app.goo.gl/rDZT9sHv4WG2iWAv9. And they are not a bar but a diving center. https://vietnamscubadiving.com/

Kein Durchkommen auf diesem kurzen Stück möglich, kein Weg erkennbar. Kleiner Schlenker über die Wege nördlich ist aber einwandfrei.

Kein Durchkommen möglich. Absperrung durch einen Zaun.
