- Mar–Oct
Rated demanding only because one source gives the Col des Rangiers a 12% maximum. Two cycling measurements give it just 8–9.4%, so the loop rides more like a moderate one. There are no winter closures, which makes it a season opener (March to October per the source). Expect small roads, forest, a short tunnel at the Passwang summit and a 500 m drop to the Doubs at Goumois.
