Marley Gap Brook flows southeasterly from Wyton Airfield to the Great Ouse at Holywell. This series will follow the part of it that runs along Conger Lane in Holywell towards St. Ives.
Suggested parking is near the Church where there is space for 1 or 2 cars. From there walk to Conger Lane. The gravelled road soon ends and a pretty footpath begins with the brook alongside and some lovely old trees.
Please note you will need tweezers to extract the log from at least one of the caches in this series
