South of Nemours, there are about 15km of unpaved track. After these 15km, it is paved and of good quality until Briare I think (we stopped at Chatillon-Coligny).
La Maison Prodigieuse, located at lock 26 of the Briare Canal, is a former lock keeper's house, beautifully restored. Nestled along the canal, this house offers unusual and comfortable accommodation, perfect for a quiet getaway.
