I’d be careful on the net, especially with a 14 year old son, as paedophiles lurk around anywhere on the net.
The ‘Plan a Trip’ section ought to be good for this though. I’m a keen boulderer and do Boulder Rock trips every so often.
If he visits the website occasionally, keep an eye out for the outings to places like Mountain Quarry and Boulder Rock, I tend to do a Boulder Rock trip every month or two, and anyone’s welcome to join us. 🙂
