WELSH MOUNTAIN ZOO I really recomend a trip to this place it is very beautiful ad included a lot of animals without being overwelming.
There is a lot of walking to be done going up and down hills so you have to be reasonably fit. I am not sure how practicle it is for people in wheelchairs or prams etc.
Be warned when you drive in its a bit like entering jurrassic park its like a drive through gate system so have your money ready or buy tickets before. Adult tickets are £14 so fairly reasonable.
