There was a good turnout of 13 junior boys lodges and four junior girls lodges at the seaside city, where they were accompanied by 12 bands.
Before they headed to Bangor, some of the local members took part in their own parade in Portadown town centre.
Photographer Tony Hendron took these pictures of the parade in Portadown on Saturday morning, while Andrew McCarroll of Pacemaker Press was in Bangor for the main event.
