I have been to WonderLa Bangalore, and itis one of the best amusements park in India, It has many exciting dry rides and many adventurous water rides too, rain dance and wave pool is very good. the water is clean. And You will find many security people all around near pools.
All the dry ride machines are also well checked, if they have a single doubt on the working system, they will stop the ride for some time do a end to end system checkup and then only they start it again so I found it very safe.
This is good for all age, they have nice rides for Kids also, and pools and simple water rides too and 3D, 7D shows are also available.
You can make a full day plan for this and enjoy fullest, They provide you separate(boys and girls) locker and locker room. which I found very clean and sophisticated. It is a complete package of adventure and fun. It is complete worth. Weekends there will be a good crowd.
If you have come to Bangalore.you must go!
