"It's always a privilege and honour for soldiers to march through the towns and cities of Wales - the places where family, loved ones and friends can welcome them.
"Saturday will be no different and the parade in Caernarfon will be another special day for The Royal Welsh."
The parade will march from the barracks in the town to Castle Square - where the troops will be inspected at 11am.
