This is an easy roadside cache at the entrance to a public park in Sunninghill Gardens. You can enter the area via Tudor or Tana Roads. Security will write down your vehicle registration number and hand you a card which you'll have to return when you exit the area - no questions asked.
Waypoint PARKN3 will take you to the parking nearest to the cache but you can also park at any of the other entrances to the park. While in the area go find the other two caches nearby, one small and another micro, GC3AE79 & GC3AE8G They are placed near the other two entrances (PARKN1 & PARKN2).
