I was there last week for my Daughter's 6th Birthday, we were there quite early in the day, so got parked on the 'hard stand' to the right of the entrance.. horrendous angled tiny parking spaces
couldn't relax all day as I was terrified I would get back to the car to be met with a few new 'door-dings' in addition to the few I have been gifted already!.
Chester Zoo is brilliant though, it's not cheap, but we were there for pretty much the whole day.. the weather was great, and more importantly the young one loved it!.
All the best guys, Gav
