10 More Trips An Hour From Paris is a set of ten unpublished daytrips to little-known places around an hour from Paris by train, available in PDF format, either separately or as a set.
Each destination includes a brief overview, the historical context and a detailed walk, as well as practical information, two colour photos and a hand-drawn colour map.
You can download the free sample trip and map (no. 2, Coulommiers) from http://anhourfromparis.com/10-more-trips-hour-paris. Here you can also download a brief overview of the 10 trips, a map of the Paris region showing the 10 destinations, a train map showing the stations mentioned in the walks and a useful explanation of French footpath signs, which appears in both my books in the Practical Details section at the end.
Happy exploring!
