Planning to get from Hue to Phong Nha-what’s the best way in terms of cost and time? Is there a direct bus, train, or private shuttle? I’d prefer a morning departure and arrival before noon so I can explore caves the same day. How reliable are these services, and which companies have the best reputation? Are seats comfortable enough for the roughly 4-5 hour journey? Any tips on booking in advance or just showing up at the station? I’d love to hear from recent travelers who did this route.
