The climb allowed participants to retrace the footsteps of St Patrick, who according to legend, once tended sheep on the mountain.
Hikers also enjoyed a programme of entertainment including traditional dance and music from the 20-strong Portglenone Comhaltas, Counties Antrim and Derry Country Fiddlers Association, and local duo, The Doone Brothers.
The event was supported by The Executive Office through Mid and East Antrim Borough Council’s Good Relations Programme.
