For travelers going from Da Nang to Phong Nha, what’s the best transport method? I’m on a budget but want a comfortable journey. Are there sleeper buses or trains that make the 10-hour trip overnight? Or is flying to Dong Hoi and then a taxi cheaper? How do you book these tickets, and is reliability an issue? Any hostel pickup services available in Da Nang? Does the train stop close to Phong Nha, or do you need an extra transfer? I’d appreciate recent experiences to avoid scams or unexpected delays.
