WoW!
This multi-cache is a nice stroll through Highgate. WoW – You will soon see the link between the first 3 waypoints when you visit them with a themed sign at each point. At each point there is a stobie pole with a four digit number high up on it. The first 3 waypoints determine the final cache location which is a short walk away.
