Bike theft is a massive issue at Cwmcarn, we were there late last summer and uniformed Police were around talking to all the riders they could.
The problem has been so bad apparently that the Police have been using covert surveillance to try and catch the thieves, including officers concealed in the trees and bushes around the area. It must be pretty bad if they’re going to those lengths.
I know lots of people who have had bikes stolen out of parked cars. And there are lots of reports of riders being followed home from Cwmcarn.
Be very careful.
