In 2000, a major redesign of the links was undertaken. Renowned architect, Pat Ruddy was tasked with upgrading the links to keep pace with the modern game. The course was lengthened considerable and nine completely new holes were added.

The other holes were improved and features like the shared greens of the 3rd and 9th, and 4th and 8th holes lend to the authenticity of the links. The upgraded course opened to much acclaim in 2002.

The Irish Ladies Close championship returned to Portsalon from 19th to 22nd of June 2005. This event was hosted to mark the 100th anniversary of the first Irish Ladies Championship to be held in Portsalon in 1905. Irish International and Curtis Cup player, Trish Mangan from Ennis, was crowned the winner on this occasion after a 3/2 win over Catherine Tucker in the final. 

In 2010, some additional improvements to the course commenced, under the guidance of 2014 Ryder Cup captain, Paul McGinley. These changes significantly improved the bunkering on several holes and also included the building of a new first tee, which really sets the tone for what lies ahead. Improvements to the course are continuing under Pauls guidance.
