Family Water Fun Options? (Karachi)

Hello everyone,

What suggestions would you have for fun activities, ideally including nature, for all ages, little kids to elders?

The snorkeling trips seem rather disappointing given the lack of marine life and under-water visibility/clarity. There's the usual beach huts and so on. We'll likely consider these if nothing else turns up. Suggestions for the best service providers/adventure clubs to go with?

Does anyone remember when dolphin watching season starts based out of Karachi?

Thanks!
