We walked with kids aged 8 and 11 years from opposite the large ship all the way to the ferris wheel along the river. Filled in a good couple of hours. Enjoyed the street art and spotting large monitor lizards. Reward for the long hot afternoon walk was an ice cream from a corner store. The water is absolutely disgusting with high levels of pollution but in the evening when we went for a short stroll it looked so much better; even pretty with all the lights shining on it. We don't plan on doing a cruise because we have seen all the best street art and would rather use our legs.
