[Closed] MTB challenge Europe and Campervan hire

Would like to set a challenge to work towards for next summer, looking at something off-road that’s going to really test - but reward with great scenery. Does anyone recommend any locations across Europe (ideally France / Italy, though open to suggestions).

Second question is on campervan hire. I know this is subjective, but it would be interesting to hear of anyone’s experiences that’s done a similar trip. Any pearls of wisdom would be greatly appreciated.

There’s 2 of us going and looking at a 2-3 week trip.
