Overall very highly- the quality of enclosures, the landscaping, facilities etc. was done to a very high standard. It was also very accessible.
The range of species was very good but has decreased over the years, and some areas (mainly the Gorilla Rainforest) no longer hold animals specific to the geographical location created (ie. Cassowary alongside Pygmy Hippo).
All in all that is just nit picking, I really enjoyed it!
