Nestled atop a hill is the Kymin, looking over Monmouthshire. To get to the top you can drive the winding roads, but be careful as they are quite narrow. The other option would be to walk along the Offa's Dyke path to get there. When you arrive there is a car park and a map to get your grounding. Before you enter there are convenient benches to sit on so you can relax with the views.
The day we attended it was free to see all due to it being an open day. Usually, it would only cost £3.00 for an adult and £1.50 for kids. Though if your a national trust member its free.
As you walk up from the car park the roundhouse stands in all its glory. With its turrets and two storeys. Originally built for the gentry who liked to picnic on the land. So they built the roundhouse so they could dine rain or shine. Built originally in 1794 with estate originally owned by the Duke of Beaufort.
As you walk in your warmly welcomed in by volunteers. Downstairs there was a talk about how the roundhouse was used as well as examples of the food eaten. Upstairs was China on display, pictures of those who had visited and a beautiful fireplace. There were also binoculars for you took look further into the valley below.
Outside of the roundhouse, as you walk back towards the car park is the navel temple. The temple was built in the early 1800s to celebrate their victories in the war. In total there are 16 admirals honoured there with Lord Horatio Nelson being one. The temple is in great condition thanks to the national trust. It's a great place as well to just sit and contemplate.
Generally, the area has stunning scenery of woodlands, great for walkers and adventurers alike. The views are stunning and when the weather is nice it's a great place for a picnic.
