The area is beautiful - we go there for walks. I love watching the boats moor and the champagne picnics set up next to them (The picnic table have BBQ grills built in and there are also brick BBQs set up).
We camp at Hurley riverside park which is great, and have walked past the campsite you mention. Looks fun but not sure where you leave your car?
I stayed there on my Duke of Edinburgh exhibition! It is basic, but pretty idyllic in the summer. The camping is right by the river with no fences, or at least it was, so could be a concern if you are taking young children?
this link suggests that it has toilets and showers, at least! I have no camped there, but have seen it from the other side of the river. It looks idyllic (v tiny) and is in a great spot. It is aimed at canoeists, cyclists and walkers I think, in that there is no vehicle access to the site, or even , as far as I remember, close to the little footbridge that goes to it. You have to transport your stuff over the bridge.
I understand this is a small campsite on an island in the Thames, run by the Environment Agency. Sounds idyllic but I just wondered if anyone has camped there and has a view on how good the facilities are, what's it like as a place to stay etc? Thanks.
