Hopton Woods, some good trails there – if you are near Craven Arms. I also like the Wrekin if you like climbing and descending.
Cannock Chase is a reasonable Forestry Commission trail centre and offers a lot of unofficial trails too. White Peak and Dark Peak offer some food routes. I live in Sutton Coldfield and although flat – Sutton Park is good for a quick spin – although doesn’t have any official MTB trails.
Going south, I quite like Clent – if you don’t mind winch and plummet. The Wyre Forest is pretty good if it is dry – otherwise it is very muddy. The Lickey Hills are the south of Birmingham alternative to Sutton Park.
There are plenty of routes around the canals – but I would go in a couple of group of friends and identify your route first. If you like drops and steps – the city centre is pretty good too.
Hope that helps a little…
