Leave Dernancourt and take the road up past the primary school. Leave the village and veer left along the road leading to the British cemetery on the road to Ribemont. Visit the British military cemetery and continue straight ahead up the hill. Take a dirt track on the right after a few hundred metres and you will find yourself at the Tribune of British Officers, where Rawlinson used his binoculars to observe the British offensive. Then, take the same path and continue along the valley keeping parallel to the road below. After crossing the fields, you will arrive in Ribemont-sur-Ancre, a village with a rich history which offers an archaeological research centre. From Ribemont, the path is indicated to Treux and back to Dernancourt. Cross the Ancre on the way out of Ribemont.
