It’s sometimes said among travellers in Vietnam that there isn’t much worth seeing between Huế and Hanoi. This is actually true if you’re following the coast. I met a fellow from Vinh, whom I asked about things to do there. He said there wasn’t anything, aside from Uncle Ho’s hometown nearby. That’s why he lived in Huế. However, on the western side of Vietnam you can find one of Vietnam’s greatest natural blessings: Phong Nha – Khe Bang national park, home of Vietnam’s biggest cave system, including Hang Son Doong – the biggest cave in the world.
