Pros:
Disc Golf in France!
Pretty easy to get to using public transportation. I updated the directions after you get off the train, since they are different from the previous directions.
Mostly undeveloped part of large park, so few interferences, except for a few walkers and dog walkers.
Two tees on most holes.
Nice grass and mostly large trees to shape your shots.
Cons:
Several of the baskets were in bad shape.
Just natural tees.
Grass was long on most of course.
Some long walks between holes, especially 2 to 3.
Other Thoughts:
This was my first chance to play outside the US. I really wanted to play the Jablines course, 24 holes and appears to be well taken care of. But the hour + cab or Uber drive from Paris just didn't add up. So, a train ticket and 10 minute walk to the course made a lot more sense.
This course has only been in for 4 years, and it looks like not much has been done since then. Be sure to print the course map off here, since there are no next tee signs.
There are a couple of nice holes 8 & 9. #8 is a low ceiling hole turning right to left, good one for your rollers. #9 is across an open field with a 15' fairway cut down the middle of high grass. Basket is back by the trees. Fun hole to finish on.
I didn't take the time to check out the rest of the park (across the tracks and a canal), mainly because I was by myself and outside of Paris. But I did find a sandwich shop for lunch, they were very accommodating with my limited French.
