"We're really looking forward to it," he said. "It's been a while since we were last together but the lads are in good shape and we can't wait to get out there. Previous results count for very little, Wales are taking a different group of players and France will be tough, as ever.
"We know that we're going to have to play well and perform somewhere near our best to stand any chance of winning. But the aim is to play as well as we can, and if that means we win games, even better."
England's game against South Africa on August 18 promises to be another tough match, but again, one that Fletcher is hugely excited by.
"It's a tough, tough place to go and play rugby - as the seniors and the Under 20s proved this summer - they are a proud nation and they love their rugby. It's the third time we've been out there with the Under 18s and it's always a good test.
"A few years back we had the likes of Owen Farrell, Jonathan Joseph, Matt Kvesic and George Ford in with us, three years later and they're all in the senior set up - so the value of these tours and getting the guys together and playing the best rugby nations is massive."
