Bicycle travel · Massif Central

Hi everyone, We’re organizing a week-long bike trip for a group of scouts. I’ve already mapped out a route using Géovélo (travel option). The teens will take the train to Nemours (or a bit beyond) and then follow the Loire à Vélo route for a good stretch (until Nevers, which they’ll bypass to the west). After Nevers, things get a bit trickier. I also wanted to avoid Moulins, so I planned for them to follow the Allier’s west bank and cross near Châtel-de-Neuvre. I’m having some doubts about the route and really want to steer clear of busy main roads as much as possible. I’d love to hear your thoughts on the route I’ve chosen, plus any tips you might have. I saw there’s the V70 veloroute, but I decided against it after hearing it has some *very* road-heavy sections.
