There are several different means to get to Yas Island, either by car, taxi, boat, bus, or the Yas Express shuttle service. If you're staying at Anantara Eastern Mangroves Abu Dhabi Hotel, you will be just under 30 minutes away from Yas Island, so you can book a taxi or go by bus. However, if you're coming all the way from the airport, it is best to opt for a car or taxi in case you have luggage. Another option would be to opt for the Abu Dhabi Link Service, which is more convenient. All you need to do is request a minibus or shuttle, and they'll pick you up and drop you off at your desired locations. Do keep in mind that travelling by taxi is slightly more expensive but is also convenient.
