A bunker, built underneath the Brookmans Park Transmitting Station, was one of 11 sites around the country. The twin-wave broadcasting facility was considered to be a crucial part of the nation’s communications strategy in the event of nuclear war.

  1. The numbering is reversed in the interactive map (clockwise) compared to the static directions map (anticlockwise). The written guidance follows the interactive map (clockwise route).

    1. Hi Andrew,
      Wow, thanks for pointing that out. I know how that happened. We made an adjustment to the route and I forgot to change the map. So grateful to you for letting me know. I have just edited the directions and changed the maps (both static and interactive). Great to have your feedback.
      Thanks again
      David

    2. No problem, David. I wouldn't have noticed other than I was working out whether to park at the start or point 3. Thanks for harmonising the maps.

      The walks on this site have given us hours of great walking this year. As the available daylight lengthens we've progressed from 4-milers to 6+. So a big thank you for all your hard work routing, posting and maintaining the walks.

    3. Hi Andrew,
      I really appreciate the feedback. It all helps me ensure the walks are accurate. So glad you are enjoying the walks. We love mapping them, and get great pleasure out of knowing others are enjoying them, too.
