Yep, really interesting place.
OK now my turn, but i hope somebody else also join to us with own tales :)
Bangkok Bar pilot station located in the approaches to Bangkok port, something about 1.5 hours on boat. This is not a pilot vessel as usial, but stationary platform near fairway:

So vessels are coming near and pilot boat taking pilots and put them on-board.

In the top of the platform there is a tower with ligthhouse:

Of course you need to get permission to land there.
Height of the tower 30-35 meters, range of light - 20 nm
