This has to be an absolute must for any Formula 1 fans and even if you don’t follow the sport back at home, it’s still a great way to spend a couple of hours. The circuit at Yas Marina is the most expensive race track in the world and construction costs are estimated around the $1.3 billion mark. The tour lasts around two hours and gives visitors exclusive access to the circuit inside and out, including areas that are normally open only to the teams.
