Looking for recommendations for summer holidays in Wales. Will be a family group, all adults. In the past couple of years we've enjoyed holidays in Pembrokeshire (near St David's), Pembrokeshire/Camarthenshire border, and also close to Llandudno/Conwy. For each I've loved being by the sea and going for coastal walks, but also having places to visit, eg Conwy Castle, Tenby, St David's. I particularly loved walking stretches of the Pembrokeshire coastal path. Does anyone have any suggestions of other places in Wales for this type of holiday?
