2) Deganwy Castle, Deganwy, Conwy

Before visiting Deganwy Castle, it's important to note that, unfortunately, there isn't much left of the castle itself as it hasn't been preserved like other castles in the area, except for a few ruins. However, we've included it in our list because the breath taking views from its elevated position will not disappoint. You'll enjoy clear vistas of Conwy and its medieval castle and walls, as well as the estuary and Llandudno from the other side. It's easy to see why Deganwy Castle was strategically built here as a vantage point.

Is Conwy castle dog friendly?


You might wonder why Conwy Castle hasn’t made the list, and sadly, it's because it's not dog-friendly. However, that doesn’t mean you and your four-legged friend can’t immerse yourselves in medieval ambiance altogether. You can still stroll and explore the UNESCO castle walls that encircle the town, taking in the area's atmosphere and charm.


So, which castle will you and your four-legged friend visit first?
