lancs blue said:Thornton Heath and Selhurst stations are about the nearest to the stadium, each about 15 mins walk from the away section. Suburban trains from Victoria call at both stations, about 25mins journey time.
East Croydon station which was mentioned earlier is further away (35-40mins walk) but you can get a train to Thornton Heath from there.
I really wouldn't consider driving to Palace, I've done it in the past and it's a nightmare to get to and there's little in the way of parking nearby so you have to get there very early to bag a decent spot.
Edit: Norwood Junction station is also about 15 mins away, you need to get to London Bridge station for those trains.
Any decent away pubs near either station?
