Can i take my beginner 12 year aold son to the hard rock cycle park

Absolutely! There is a track just for kids learning to ride!

Yes,they have a separate track for kids

Yup, they have a pretty good peewee track, and as he progresses they have a step up from that called the outback track

Yes

There are a few tracks for all skill levels probably the best track to start on for an older beginner at hardrock is the outback track
