Cabo Roig - huge Irish influence in the whole area. Irish expats, tourists, bars and even Irish supermarkets.
Two areas the strip near the N332, loads of bars, entertainment within walking distance to the beach and lots of small urbanisations on both sides on the main road. Can be a very quiet area during the day, but is buzzing of a night time. There’s a weekly market between the strip and the beach and a night market every evening in the summer months
Or try inland a bit at Lomas de Cabo Roig, quieter area, less touristy, but still a great selection of bars/restaurants etc.
