Could anyone tell me if there is a supermarket or similar near the canal in Auxerre please?
The Yonne River travels right through the center of town so provisioning should not be difficult. There is an E Leclerc, a large supermarket, about one block to the east of Aquarelle or the boat base located on the east side of the Yonne River. E Leclerc is located at 16 Avenue Jean Jaurès which should not be more than a 5 to 10 minute walk from the river.
Thank you very much Sarastro that's exactly what I needed!
