Sorry missed this. From T4 I have not found a suitable starting point, it's a bit like T3 LHR T3 with no intuitive pedestrian access. So I take the free airside bus to T1, keeping walking past the carpark until you find and cross this bridge

If you happen to be here during a weekend, try running to this park (El Capricho) - it's only open on the weekends
