What are the landforms in Ha Long Bay?

What are Ha Long Bays major landforms and geological features?

Okay, so Ha Long Bay, right? I've only seen pictures, but wow.

It's mainly limestone karst landscape. That much I think I know for sure.

Basically, think lots of cone-shaped hills – fengcong – and these tall, isolated limestone towers, they call 'em fenglin. Like, straight out of a fantasy movie.

I saw a doc somewhere (uh, Netflix maybe? 2022?), and they were talking about how the whole thing's been developing since the Miocene... which, let's be honest, I had to Google.

It's all thanks to old phreatic caves, and those old karstic foot caves, and marine notch caves. A whole mishmash, and the way they explain it is real nice, like the scenery is just, perfect.

These caves and whatnot carved all this crazy limestone scenery that's supposedly unique to Ha Long... And I really, really want to see it for myself one day. I'd pack light so I could by cheap stuff over there haha.

My pal, Dave, went last spring. He said the boat tour was like, 30 bucks, and that's cheap. I can't confirm his numbers are accurate though, Dave's cheap.
