Many holidaymakers staying on the Causeway coast are expected to be among the crowds enjoying the Twelfth in the village of Bushmills.
Up to 50 lodges – including Giant’s Causeway LOL 1195 – will take part in the North Antrim Combine demonstration, which was last held in the coastal venue five years ago.
Brethren on parade will represent a total of five districts - Ballymoney, Ballycastle, Rasharkin, Cloughmills and hosts for the day, Bushmills.
Among the rich variety of music on display to the anticipated large number of spectators, will be the distinctive sight and sound of Lambeg drums, which will accompany up to 30 bands encompassing the accordion, flute and pipe band genres.
The main parade will move off from the Castlecatt Road at 1pm, proceeding the short route through the village to the demonstration field on the Whitepark Road for the religious service.
The guest speaker on the platform will be the past Deputy Grand Master of the Grand Orange Lodge of Ireland, Rev Alistair Smyth.
Meanwhile the most senior Orangeman in Scotland will be among those enjoying the festivities in Coleraine. Henry Dunbar will join more than 60 lodges.
