Yr Wyddfa is a bell tent on a farm in Llysfaen, near Abergele. It's for two people and you can bring two dogs.
It's a proper camping setup. There's a double bed in the tent and it has electricity and a kettle. For cooking and showers, you use a shared block a short walk away. It's clean and has what you need. You get the field to yourselves, it's enclosed so the dogs are safe. You can use a barbecue.
The farm is quiet. You're about three miles from Pensarn beach, which is a long sandy beach. It's good for dog walks. Gwrych Castle is up the hill, you can walk to it. It's the one from the telly.
Conwy is about a fifteen minute drive. That's where the big castle is. Llandudno is a bit further, maybe twenty five minutes. It's a proper Victorian seaside town with a pier. The Conwy Valley and Snowdonia are inland, you can get to some trails in half an hour if the traffic's alright.
It's a 2 Star rating. That means it's basic but functional. The shared facilities are what you'd expect from a good campsite. Bedding and towels are included. There's parking right by the field.
