Tickets for the Singha Premiership Rugby 7s Series at BT Sport Cardiff Arms Park later this month are on sale now at the Liberty Stadium Ticket Office.
The evening on Friday, July 22, will see the Blues once again host the regional event, with the reigning champions Newport Gwent Dragons, the Ospreys and the Scarlets and their supporters enjoying carnival themed fun.
Tickets are priced at 10 for adults, £5 for concessions.
Ospreys 2016/17 season members are entitled to free entry for this event but need to pre-book their ticket from the Liberty Stadium Ticket Office in advance. There will be no free entry on the night without a pre-booked ticket.
Further details of the Carnival activities and entertainment will be confirmed in due course.
