Son Doong Cave – the world’s largest – and its neighbor, which are located in a UNESCO-recognized park in Viet Nam, wowed millions of American viewers as the American Broadcasting Company (ABC) aired live a signature program featuring the two caves’ resplendence on Wednesday.

ABC broadcast the show accentuating the astounding magnificence of Son Doong and En (Swallow) Caves on “Good Morning America,” a much-loved program watched by an average of six million subscribers every day.

The caves are secluded in the core area of the UNESCO-recognized Phong Nha-Ke Bang National Park, located in the north-central province of Quang Binh.

En Cave is around two kilometers from Son Doong.

It was the first time that ABC had reported live from inside the grottos, its crew members told Tuoi Tre (Youth) newspaper reporters, who joined them while filming last week.

The high-profile show aired live at 6:00 am East Coast time on Wednesday, or 6:00 pm the same day in Vietnamese time.
