Dinosaur World stood opposite the boating lake and was a very popular attraction in the park until 2003. Advertised as the largest collection of dinosaurs in the British Isles, the collection of over 50 life-sized models made realistic noises and were shown in their natural habitats. New models were added every year for 10 years. The site was taken over by Conwy Council in 2009 and Canolfan Tu Fewn Tu Allan (Indoor Outdoor Centre) was opened on June 30th, 2011. At the time the centre opened Annette Evans, of Conwy Education Services, described the centre: “The centre will have an educational focus for children, staff and families to explore the natural environment through hands-on experiences. The building will be a training base for both pre-school and school staff within Conwy, whilst the outdoor area will give children the opportunity to enjoy and appreciate nature on their doorstep.”
For many years a dinosaur stood in the grounds of the Dulas Arms, Llanddulas, to advertise Dinosaur World. It could be seen from the A55 Expressway when travelling towards Colwyn Bay.
