Leinster made light work of Biarritz at a sunny RDS to reach the Amlin Challenge Cup final.
The 44 - 16 win means Joe Schmidt's men will return to the same venue on May 17th to face Stade Francais in the final.
The first half was dominated by Leinster and the province got off to a fine start with Jamie Heaslip getting the opening try in the fifth minute.
Dimitri Yachvili kicked three penalties for the French side to stay in it.
But Jonathan Sexton and Heaslip then got two more tries just before the break to give Leinster a 24 - 9 lead.
Isa Nacewa added another try for Leinster after half time with Ian Madigan converting before Nacewa set up Brian O'Driscoll for a try on 63 minutes.
Biarritz finally got a try of their own five minutes later as Arnaud Heguy found a gap.
But it was too little too late for the French side as Leinster advanced to a final on home soil.
