Here is La Tour-du-Pin airport created by Claude Roure.
The La Tour-du-Pin/Cessieu aerodrome, between Grenoble St Geoirs to the south and Lyon Saint Exupéry to the northwest, has a grass runway 12/30 of 560x60.
Activity: ULM (the UL2V club is the largest in Rhône-Alpes), gliders, model aircraft (note: another mod exists on the web, but it does not conform to reality).
