In abu dhabi, uae which park should i go for cycling and playing

Nad Al Sheba.

Explanation:

There are quite a few cycling parks in UAE since it's not allowed to cycle on the regular roads. The one I found interesting is Nad Al Sheba. It has a magnificent view of Burj Khalifa and you can see very well downtown of Dubai. It offers an 8 km, 6 km or 4 km paths for people, whether they want to go cycling or running. There are plenty of changing rooms, toilets, lockers and showers alongside the road, which is great for urgent situations or simply if you want to freshen up a bit and rest for a while. When it comes to night cycling or running, it's very bright and beautiful, romantic in a way, but you would still need to use lights on your own bike just to be safe.

As I said, this is my own opinion and if you are looking for something different, you could always ask the locals to help you out.
