Love/Hate relationship here.
Agree with Samurai. If you are carrying speed round there, real speed, then its great. There are loads of jumps there. They don't have to be signposted to be jumps. Trouble is, if you're not carrying speed they will be ickle bumps, which will be just rolled over.
I don't expect a battering there – rocks, roots etc. However, I'm always suprised to see people rocking up on beefy 6 inch bikes, which look like being set up for the alps, with the owners padded up. Unless you are Mark Weir you're not going to pump/jump 35lb bikes around there. Thus, I agree with the MBR subscriber comment.
In summary, its great for a weekday blast when its quiet. IMO – avoid weekends at all costs.
NB. In addition, the disposal of used inner tubes into trees is not mandatory. Absolute throbbers.
