Fearless Ryan Deboodt rowed into the darkness of Tham Khoun Xe, Laos, flying a drone high overhead.

Doing so allowed Ryan to capture the gigantic scale of the cave – his illuminated kayak appearing as just a small speck in the cave’s waters.

Average stretches of the cave measure 76 meters wide and 56 meters height, with some stalagmites measuring 20 meters in height.

The adventurer – from Kimball in Nebraska, USA – shot the breath-taking series between December 13 and December 15 last year.

Ryan, 32, said: “The setting for this cave is absolutely stunning and once inside, the cave is beautiful.

“Just in the entrance there is a section of the cave you can climb up to a natural balcony that has a view that won’t be forgotten looking towards the entrance.

“Deeper inside the cave there are huge passages complete with clear water.”

One of the most amazing elements of the cave for Ryan was a small area called Cathedral Passage – a straight passage with a ceiling that resembles a cathedral.

The first international explorer to visit Tham Khoun Xe’s cavern was Paul Macey in 1905.

It has been estimated by speleologists that at least half of the world’s caves have not been visited by humans.

Ryan, who is currently based in Beijing, China, has spent a large amount of the last five years documenting their stunning interiors.

He added: “I feel that caves are one of the least understood places.

“With my photography and filming, I’m always trying to show how beautiful and otherworldly these places are.

“I want everyone to know that caves aren’t just holes in the ground, but stunning and unique places.”
