In reply to Ed Booth:
Tricky but doable decent I would have thought.
You will need to keep a really close eye on them though once down there - round the back of the main bouldering block are some big holes a toddler could fall down and end up in the sea.
Personally I’m not sure I would take my toddler down there, certainly not on my own, but if you’re a couple who don’t mind taking it in turns to watch them while the other climbs then I guess it could be ok.
Other options that would be much more kid friendly would be Northcott and Hartland further north/east along the coast, or Godrevy quite a long further south/west.
