    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

    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.
