Between Hampstead and Golders Green tube stations. Outdoor cruising in the woods on the north side of the hill just below Jack Straws Castle (straight pub). The adjacent car park has direct access to the Heath (it is recommended that you do not park your car in the Jack Straws car park - find an alternative parking spot). Turn right at the bottom of the car park to get to where the action is. It is true that action can also be found during the daytime when the weather is warmer, although it is in the evenings after I 1.00 which is still the busiest time.
