There are bike rental services in most of the towns on the route.
It is really worth renting side bags when renting a bike. They are very practical for carrying clothes and a picnic, even for a day trip. Some bike renters also provide trailer rentals or third wheel trailer bikes for your children.
How to find them
On the trail maps (under the “i”, "bike rental / repairers" section) tab) or using the search engine.
