Camp sites near Angers and Saint-Malo

[Battlecat]

I'm taking the bike over to north-west France for a long weekend ride, next weekend.

I've worked out a bit of a route and quite fancy staying on a couple of camp sites on Friday and Saturday nights. I may be mad as it means carrying a tent and sleeping bag on a bike when a B&B would be the easier option, but i just fancy it.

Does anyone have an recommendations for camp sites ideally situated next to or very near the Loire River in the Angers area? Doesn't have to be very close to Angers - I guess within 20 miles is fine.

And the same question for the Saint-Malo area.

Many thanks

Ollie
