We left from Maida Vale and walked about 5.5kms in a north, north easterly direction entering Hampstead Heath on its south west boundary and thence zigzagged with the paths and terrain to approach Parliament Hill from the north west. Its altitude and prominence is so modest that it wasn't until we reached the 'lookout' that we realised we had summited. It was delightful late summer weather. We returned to Maida Vale via Kentish Town and Camden and the canal path past Regent's Park - about 15km return.
