Departures are easy, they follow SIDs/NPRs below 4000 feet (mostly), but you will search in vain for a map showing precise arrival routes, the reason being that they don't exist. The flightpath between the arrival point (Bovingdon, Lambourne, Biggin or Ockham), with or without holding there, and the final approach to the runway is determined by the controller handling each flight, the object being to integrate arrivals from various directions efficiently and thereby maximize the landing rate.
All that can reasonably be predicted is that the flightpath will follow an S- or U-shaped curve, depending on which arrival point and which runway direction is in use.
