The eco-extravaganza will boast a special Eco Trail, for visitors to follow as they explore their way through the zoo, running daily, from 11am-3.30pm.
Green enthusiasts can fill in the trail map as they go and then hand them in at the Budongo Trail to be in with a chance of winning some special goodies, including an Edinburgh Zoo family pass. The Budongo Trail – home to the zoo’s lively chimps – will be bursting with green ideas on composting, reducing waste and even recycling.
Eco-warriors can then pledge to do their part for the environment, with either a blue or green thumb print.
Activities will take place in the Budongo Lecture Theatre, starting today and running until Sunday, February 17.
