Marooned in the middle of Hoan Kiem Lake is this unassuming quiet temple. It's none of the most visited temples in the whole of Vietnam, so expect to be fighting for elbow room a little. However, if you're lucky and the crowds aren't there, it's a great place to sit and reflect on life for a while. It's also a place which locals come to give offerings to the gods including burning fake money. The temple is connected to the mainland by an attractive bridge which is worth an instagram shot for sure.
