The Porter Brook Path

The Sheaf & Porter Rivers Trust focus on the section between Hunters Bar and Sheffield Station, which makes up the lower Porter Brook.

The Upper Porter Brook is lovingly cared for by the Friends of the Porter Valley.

The following is the route between the confluence with Sheaf at Platform 5a of Sheffield Station to high up on the Moors, bordering the Peak District National Park, at Fulwood Lane

Also check out a history walk by 'Urban Rambles' ...but do check bus timetables first as this post is over 4 years old:
