From Headley Heath we follow the woodland footpath along Tye and Buckland Lanes, through Dawcombe Nature Reserve. We then cross a bridge over the M25 towards Walton Heath. Great views South over the North Downs. Then we cross Walton Heath and follow the path to Mere Pond for a break at 7km (coffee shop available), through the village and follow the path through fields and woodland. Heading back we pass under the M25, and back up to Headley Heath, to the car park. Several stiles (not all dog friendly). May be livestock in fields.
