Details of this geocache trail can be found at the first cache.
Cross the bridge and keep going up the hill on the pavement. Turn right back down the hill towards Beckenham Place Park again.
You are looking for a large tube.
This series is being made open to all again (rather than premium only) - but caches will be archived as they get damaged or go missing, and the series will eventually be retired. Please look after the caches to preserve them as long as possible, and happy hunting!
