Great idea! Loved the Horseshoe Pass meet.
Location Wrexham
Possible ideas for a meet or "stop offs" on a bit of a run..
Pontcysyllte Aqueduct, reasonable sized car park on the Trevor side and a reasonable pub, the "Telford Inn".
There are a few national trust places in the area (Chirk Castle and Erddig) but I'd imagine permission (or membership or ticket price entry) would be needed.
Couple of other places I could recommend for good food and a good sized car park are the Poachers Pocket and Oswalds Cross, although neither are technically in Wales... but close enough
