Wentwood is a 309m hill that counts for both Newport and Monmouthshire, it is topped by an accessible trig point, but one without views as it is heavily wooded. Wentwood is a large forest with many paths cutting through it and multiple well-maintained and signposted parking areas for lots of cars.
You can actually park much closer to the summit than I did on the route above as there is an unmarked car park directly on the route I walked as you cross the second road.
The tracks are forest roads, so wide and gravel, flooded in places after heavy rain though. The trig point is off the main path and through a narrow and quite overgrown – during the summer anyway – but it is only a short way from the main path.
There are many trails through the forest, so you could easily make this a longer or shorter route. There are probably some places with decent views as well, as you can’t see a great deal from the trig point – it might be a better spot in winter.
