Anyone know of any? Necessary because climbing with kids in tow. VS-E1 types grades. Thank you!

Slate, Holyhead Mountain, Upper Tier Tremadog, some areas of the Grochan, or sport options on the coast.

You said North Wales rather than just Snowdonia, so in that case I'd suggest  Pot Hole Quarry (Three Springs) especially at the grades you mentioned.

Visited this place for the first time last year and was very impressed. Craig Y Tonnau  

Some excellent easier routes to suit youngsters of limited experience.

There was an access problem due to forestry works going on which we only found out about after our visit.

Can't think of the name off the top of my head but there is a nice little crag just above Betwys y Coed
