This is a fantastic, free event especially if you are staying in the area as getting to/from the event will be easier. Consider using the Causeway Rambler 402 Translink service to Portrush from Dunseverick Castle. You can walk to the bus stop from Bayview Farm in 25 minutes via the Feigh Road, or drive and park for free. It could save time with the park and ride, usually situated on the Ballywillan Road Portrush.
