I have not been to the Welsh Hawking Centre for a while now . It is on the site of the former Barry Zoo and most of the old enclosures are still there , converted to house birds of prey . There are some photos in the gallery which will give you an idea .
Silent World , Tenby , is based on what was a chapel in the middle of a graveyard ! The aquarium is on the ground floor with the rest upstairs , not very big but some very nice specimens on show and friendly owners .
There is a WWT Centre near Llanelli with the usual collection of ducks , geese and swans plus breeding flamingos , also a large reserve area with good views and lots of wild birds .
Swansea has a large greenhouse called Plantasia which has a small collection including cotton-top tamarins ex-Penscynor , birds , reptiles , fish etc.
Margam Park near Port Talbot has large deer herds including some Pere David's .
