Phong Nha is an adventurer’s paradise. Millions of years of flooding have chiseled out the world’s largest caves, meandering rivers entwine ancient karsts, and jungle-clad mountains lend an otherworldly atmosphere.
Colossal caves may be the main draw, but linger a little longer and Phong Nha-Ke Bang National Park will reveal hiking trails, countryside lanes, and rivers perfect for kayaking.
