This footpath from Stotfold to Radwell runs along the Beds/Herts border so I don't know which county this cache is in. You can get from either end although if you start from Stotfold, you will hhave to cross the A507 which can be busy at times - take care.
You are looking for a bison tube with just a log in, so bring your own pen/pencil.
