Directions
The stadium is located around one and a half miles away from Southampton station (where there is also quite a large car park), which should take about 30 minutes to walk.
There is also a shuttle bus in operation taking fans from the station to the ground. This operates from the Blechynden Terrace bus stop outside the station.
Turn left out of the station' s southern entrance and walk up Western Esplanade, which becomes Civic Centre Road. Remain on the Civic Centre Road and walk between the Civic Centre and the Marlands Shopping Centre.
Eventually a crossroads is reached with the Nationwide Building Society on one corner and Lloyds Bank on another. Cross into New Road and follow this road across a park and past a college.
Eventually you will reach a complex road junction with a number of traffic lights. Cross Kings Way into Northam Road and follow this road for quarter of a mile until you reach the ground on your right.
There are signs provided by the local council, which direct fans from the station to the ground. You can also walk from St. Denys Station, which is a good 25 minute walk away. This area has some good pubs!

Ground: Left, at the end of Northam Road.
Remember, it's in a Group Save area that can cut fares in half if four of you can travel together, and any various travelcards will make it even cheaper.
But of course, check the megabus site first, it could make the Group Save offer rather expensive!
