The 3rd Annual Rainforest Challenge drew experienced off-roaders from Vietnam, Thailand and Laos, to the northern province of Quang Ninh from August 25 – 30.
The Tuan Chau Tourist Zone's natural stone cliffs, streams and muddy lagoons proved an ideal staging ground for the 30 teams of off-road drivers.
This year's competition drew a number of female drivers.
To make the competition more challenging, obstacles and traps were laid, including deep ponds blocking the road. Several racers lost cars in rocky stream beds and sharp mountain gorges.
Mosquitoes and jungle leeches added more thrills to the adventure.
