Hiking in Thurrock, England follows the Thames through a landscape of sea walls, marsh edges, and old chalk workings turned green. Walk out from Tilbury toward East Tilbury and Stanford-le-Hope, trace the estuary near Thurrock Thameside Nature Park at Mucking, or head inland to the lakes and quarry rims of Chafford Gorges. Thurrock pairs big-sky river views with pockets of unexpected wild ground.
