The Dragon's Lair tour welcomes visitors to retrace the famous footsteps of the Grand Slam winning Welsh rugby squad, the world's greatest football stars and global icons from the live music scene.
The traditional rugby tour also features the Wales national squad's home changing room, the hallowed turf and the Ray Gravell Press Conference Suite.
The tours operate hourly, all year round, and are available in English, French and Welsh and have seen thousands of extra tourists through the doors since last summer at the venue which in the same year scooped the Rugby Venue of the Year award.
And with many tourists now rating their experiences online, the Millennium Stadium has also received the TripAdvisor 2012 Certificate of Excellence award which recognises consistently excellent traveller reviews on the popular tourism site.
"We are extremely proud of our reputation as a multi-event venue as well as the heritage and tradition of Welsh rugby on which the foundations of our Stadium are built," said Millennium Stadium Manager Gerry Toms.
"The versatility of the Stadium appeals to visitors from all over the world - not just the core rugby fans but motorsports, football and music lovers alike - and we're thrilled that our tours are attracting more satisfied customers than ever before."
As the Tours have attracted thousands of extra visitors through the doors over 12 months, an additional 600,000 plus spectators have attended major events in the same period.
Wales' Grand Slam Winning RBS 6 Nations Championship played out at the venue which also scooped the Rugby Venue of the Year award during the 2011/2012 season.
Additionally, during Wales' exciting 2011 Rugby World Cup campaign, the stadium attracted crowds greater than those in the RWC host nation, some 62,000 fans, when it opened up its doors for the free live television screening of Wales' Bronze Medal game.
Millennium Stadium Tours start at the WRU Store, No.8 Westgate St. (situated between Gates 3 & 4) and are available on the hour Monday to Saturday between 10am and 5pm and on Sundays and Bank Holidays between 10am and 4pm.
