The Millennium Stadium is the stage for a feast of rugby this weekend and fans are advised to plan their journeys into the city centre early to avoid congestion and costly parking charges.
The semi-final double header sees Sale Sharks take on Leicester Tigers at 2.30pm and Cardiff Blues face the Ospreys at 5.15pm on Saturday March 24.
An estimated crowd of 50,000 is expected at the stadium and the best way for fans and visitors to travel to Cardiff is on public transport.

Coaches should leave the M4 at J32 and use the parking at the Civic centre. Parking opens at 9am. The last bus will leave the pick-up point at 8.30pm, with the car park closing at 9pm.
