Amazing photographs! The shots of that incredibly green water in the cave were spectacular!

That rugged coastline with the sea-carved rocks reminded me of a few spots in California with similar geography.

Viet Nam and Thailand are on my travel itinerary for 2023, and I'm really excited about it. I'll be researching Quang Binh now to see if it's someplace I can or should add to my route.

Thanks for this stellar post!!

Cheers!
