What sort of riding do you like?
Yearsley is good fun but gets really boggy this time of year
Dalby has a good variety of trails, the blue/red/black ride pretty well all year. The off piste there is really good, little bit sloppy now but dries out quicker than yearsley
Stainburn has a couple of graded rocky trails and a few good off piste lines
Leeds urban bike park – shortish loop trails with some jump lines to play on
Grenoside/Wharncliffe in Sheffield is well worth a trip. Grenoside for the tamer trails, Wharncliffe has a bit of everything from mild bermy trails that ride well all year to steep rocky tech
