It is very easy to get to the festival site by foot from Reading train station it takes about 15 Minutes.

On exiting the station go right on to Station hill, this turns in to Tudor Rd.
At the lights. Turn right onto Caversham road (by RG1 night club). You should go under a railway bridge.
Its probably best to cross the road onto the side with the fire station on it.
At the roundabout with the TGI Restaurant on it carry straight on up the Caversham Road.
On the next roundabout with the Hotel and Gorge Cafe on it , turn left in to Richfield Avenue.
Just follow the crowd.
