K for Karaoke is big in Vietnam, and Souvik has had his share of them in office parties, but my pick is Kayaking.
The beauty of Halong Bay and Lan Ha bay is best appreciated in a kayak! Doesn’t matter if you’re a novice; just some basic instructions and you can be off for some fun on the water. Unless you’re the team of Uju & Sindhu, being magnetically attracted to the underside of junk boats and simply going around in circles!
