The area is rich in industrial and natural heritage and the river itself has a long history as a trade route and has changed shape many times over the years. Clearwell Caves is a classic and a great experience for all the family, kids and adults, it is full of old mining artefacts, displays, a working blacksmiths and many other interesting unexpected things. Near to there is Puzzlewood, this is an area of ancient woodland with walk ways through rock gullies and trees growing out of the rocks a really live fantasy woodland, they also have animals and a willow maze for the kids. Dean Heritage centre is another place worth a visit, there are also some great Castles close by the most notable being Raglan, Goodrich and Chepstow.
The famous Tintern Abbey is very close by too. The Wye Valley is also famous for it's old watering holes, here are some of my favorites for their great location and character The Boat Inn in Redbrook (actually Penallt but it's best to park in Redbrook and walk over the river bridge) The Brockweir Inn, The Ostrich Inn, Newland.
Walking wise the Wye Valley AONB offer some good info on walks in the area including The Wye Valley Walk and Offa's Dyke both these trails pass through Wye Tipi Camping where you are welcome to get a tipi for the night, we can even arrange for you to canoe part of the walk if you are allowed, and are heading south! Monmouth Tourist Information Centre has short walk guides for the area which are very informative, giving details of history and historic events, there are walks around the Biblins and King Arthurs cave on the Doward Hill to Symonds Yat West and the Highmeadow trail is great taking you through the valley on paths less trodden, enjoy.
