Depends on what you want to do and see. Travel between the two cities is easy and taxis are plentiful. The time to travel is around 1/1.5 hours depending on where you are going.
Things to see in Abu Dhabi would be:
Sheikh Zayed Mosque
Saadiyat Island - Manarat
The Mangroves (kayak)
The Corniche for the sea
You could easily do a morning tour of the mosque, followed by coffee (or lunch) at Emirates Palace and then head into the sand dunes for the afternoon with a meal in the desert. almost 7 years ago
If you only have two days. You can see all of Abu Dhabi's attractions (listed above) in one day. You will most likely return to Dubai next time and spend your whole trip there. Better to get it out of the way this trip over 3 years agoAnswered by Leepa Poulose via WorldNomads.com
