Book direct. Stay independent.

Coastline, mountains, and national parks (Snowdonia and the Brecon Beacons among them), with independent stays scattered right through both. Wales has more castles per square mile than any other country in Europe, a direct legacy of centuries as contested territory, and it's genuinely hard to drive far without passing one. The coastline, especially Pembrokeshire, holds up against anywhere in Britain for proper cliff-and-beach walking.
