Deputy Prime Minister Angela Rayner also joined the visit.
They visited Newquay Orchard - meeting volunteers, staff and pupils, learning more about the services the CIC offers on site.
Their next stop took them to the Nansledan housing development - and Nansledan School where pupils were waiting to greet them. King Charles reportedly wanted to show the PM and Deputy Prime Minister a project that promotes both traditional materials and sustainable living.
