Ha Long Bay Overnight Cruise: What to Bring and What to Expect

Packing right makes a difference

A Ha Long Bay cruise is not like other Vietnam travel days. You’re on a boat, the climate is humid, there’s kayaking involved, and you’re eating multiple meals in a confined space with strangers. Here’s what I’d actually pack.

What to bring

Swimwear (obviously) and a rash guard — the sun on water is strong and sunburn on a boat with no shade is miserable. Motion sickness tablets if you’re susceptible (the bay is generally calm but not always). Reef-safe sunscreen. A dry bag for your electronics during kayaking — some boats provide these, many don’t. A light layer for evenings, which can be surprisingly cool on the water. Cash in VND for onboard drinks and tips.

What to leave behind

Big luggage — most boats have small cabins and storage is limited. Most cruise operators allow you to leave your main bag at their Hanoi partner hotel for free. Bring only what you need for 1–2 nights in a daypack.

What the days actually look like

Day 1: board around noon, sail to first stop, kayaking or swimming, cave visit, sunset drinks on deck, seafood dinner, squid fishing in the dark if offered. Day 2: sunrise on deck (set an alarm — genuinely beautiful), breakfast, more kayaking or swimming, return to port by noon. It’s a simple itinerary but it doesn’t need to be complex — the scenery does the work.

The thing that surprised me

The other passengers. On a mid-range boat you’re sharing meals and experiences with 12–20 people for two days — it’s unexpectedly social and I’ve had some genuinely good conversations on Ha Long Bay boats. It’s also where I got most of my Vietnam travel recommendations for the rest of that trip.
