Based on readers’ comments, the U.K.-based newspaper recommends that holiday-goers check out the observation deck at the top of the Lotte Center, Vietnam’s third highest skyscraper.

Among the biggest highlights of the Observation Deck are the skywalks, two vertigo-inducing glass sky decks that jut out from the side of the building, The Guardian said.

There is a fixed camera on the ceiling of one of the skywalks, allowing visitors to capture photos of themselves looking down at the city below.

The deck is open to visitors until midnight. Tourism in Hanoi has been booming, with the capital city welcoming 5.7 million foreign visitors last year.

The capital was named among the top 15 destinations in the world by TripAdvisor travelers in 2018.
