There is nothing as romantic as a slow bike along a canal in rural France. If you talk to your hotel, guest house or AirBnB, they should be able to help you rent a bike. Ours were delivered and were only 20 Euros per day. Once you have the bikes, just head to the canal. It's a really easy to find unique features in Reims. Ride along the south side of the canal (that's where the paved trail is) and just head east.

The first real town you will come across is Sillery. You can keep going or not even make it that far. This is totally up to you. Take your time and be sure to go on detours to fields, vineyards or even to do a champagne tasting at one of the famous houses. When you get to Sillery, there is a grocery store only half a block away from the trail that sells bread, wine, cheese and whatever else you need to have a picnic in the grass along the side of the canal. It's so romantic, you'll feel as if you were living in a Monet painting.
