“The zoo will still be open without entry charge as promised but without a 4 x 4 vehicle we would not recommend coming, we had considered closing today but we realise not everyone looks at Facebook and we would not like to turn anyone away who has made the trip to come.”
The zoo has remained open for West Lothian residents who wish to walk outside and see the animals, and have allowed free entry to all visitors as long as they adhere to social distancing.
Locals are allowed to visit for free until January 3, excluding New Years day after initially offering it for Boxing Day alone.
Voluntary donations can still be made to the zoo on entry however.
Edinburgh Zoo has also announced that it will be unable to open today due to the icy weather.
In a twitter post, they stated: “Due to ice we are unable to open the park for 10am - an email will be sent to all visitors with pre-booked tickets.
"We hope to be open a little later today - stay tuned for updates.”
