Great variety of birds both resident and wild.  Many hides around the two sides of the Wetland Centre.  In summer a huge variety of insects can be found when it's a quieter time for the birds.  Something of interest for all wildlife enthusiastic family members.  Weekends are always busy so the more serious birder may prefer weekday visiting if they're free to do so.  Plenty of events and organised activities.  A quiet retreat in close proximity to the centre of London.
