We have stopped on Parc Derwen it was a lovely site not far from Betws-y-Coed some time agoBron Derw in Llanrwst is a great place - actually if you book early there is a CL with own toilet block and 2 other entirely separate areas, one for adults only, both with toilet blocks.
An easy walk to the village including livestock market and eateries, or easy access to surrounding area. Very welcoming hosts and lots of space with far reaching views.
That is why we book it because it was the adult area also i got a service pitch next to the facilities .Just to be clear Parc Derwen is the adults area of Bron Derw!
