We done both those areas over the last few days. Sally Oak on the W&B has a very busy towpath with walkers and cyclists, it does not feel threatening at all given the number of people about in the daytime at least. Busy with boats too.
Camp Hill is a different matter! Approaching Bordesley junction from Birmingham it is a real post apocalyptic scene, every surface is covered in graffiti, and the surrounding area is a right mess. The top on Camp Hill locks is worse than it was, the services are closed and trashed and some of the surrounding buildings are demolished, there is no longer any secure mooring there. That said, yesterday there were few people about on the flight and the only issue was stiff paddles. From Camp Hill to Catherine de Barnes has few redeeming features, even when you get past to worst of the rubbish in the water at Olton, it’s in a gloomy cutting.
