One of my favourite parts of the world – amazing for food, people, customs, culture, architecture, landscapes and general chaos. NW Vietnam (beyond Sappa) is mind-blowing: best done by bike or motorbike if you have time. HCM and Hanoi are great. Mekong Delta is fascinating and very unusual. Maybe skip Dalat. Loved Laos too – mountains north of the capital are stunning, tho places like Vang Vien sound hideously full of idiot backpackers nowadays. Luang Prabang is stunning, but probably rammed. My general tip for the whole region would be get off the beaten track – most of the places we enjoyed the most were those where we got away from other tourists, and that was back in 1999. It’s easier said than done, but well worth the effort. Hit some main attractions yes, but defo try to get away to a couple of random places in between the hotspots. Have fun!
