Walking the Hidden River Fleet

A ten-mile guided walk tracing the path of the Fleet River from Hampstead Heath along its underground route through Dartmouth Park, using clues such as street names and pipes that are noisier than usual to keep track of it. Along the way you'll hear about the history of the areas you pass and listen to stories about the people who lived on the river's banks. Meet at Hampstead tube. Tickets for shorter sections of the walk are also available.
