Vietnam's climate varies from north to south and season to season, so pack light layers you can mix and match. Here are the essentials.
Clothing
Lightweight, breathable clothes for the heat; a light rain jacket; a warm layer if you're heading to Sapa or visiting the north in winter; and modest cover-ups (shoulders and knees) for temples and pagodas.
Footwear
Comfortable walking shoes for cities and trekking, plus sandals for the beach and cruise decks.
Don't forget
Sunscreen, insect repellent, a reusable water bottle, a universal adapter, and any personal medication. Everything else you can pick up easily along the way — and your guide is always on hand to help.
