Drones, kayaks, and caves. A great combo in this recently released video by Ryan Deboodt. He says:
Shot during a two day kayaking trip, this film takes you on a journey through Tham Khoun Xe on the Xe Bang Fai River.
Tham Khoun Xe is a river cave carved by the mighty Xe Bang Fai River and is located in Hin Nam No National Protected Area in central Laos. At 7 km long and with an average width and height of 76m and 56m respectively, it is considered one of the largest active river caves in the world.
From the Adventure Journal:
The cave is more than four miles long and averages about 250 feet wide and 120 feet tall. Locals have fished near its entrance for centuries and climbed the walls to gather eggs from bird’s nests. Paddling it isn’t new, either—the first Europeans came in 1904 and the first raft journey came just a year later. Tham Khoun Xe was then closed to outsiders for nearly a century, until opening to kayaking 10 years ago.
