Looks like I'll be in Paris from July 13 - Aug 5. I'll be staying in La Defense - dog sitting for someone - which looks like it's probably not the most exciting area but well connected enough? Haven't read through this whole thread yet but assuming spot/park recommendations have probably already been dropped on page 1-2.
If any pals are around, would be stoked to meet up and go skate.
Don't trip about being in La Défense, it's super well connected to downtown Paris with the metro (ride isn't too short but also not too long) and most importantly, although it's no longer what it used to be 10, 20 years ago La Défense is basically ten square kilometers of spots, it's its own microcosm and full of nooks and crannies with all kinds of skatable stuff ranging from nugs you've definitely seen in videos (although a lot of them are gone now) to the most obscure piss corner. For a skateboarder it's basically akin to staying in Créteil or Ivry, you'll be alright.
(Anyone know if people still skate literally inside the mall on rainy Sundays there? Mega group sessions used to go down there with Fabien Le Toullec and all the usual Dôme heads, flatground lines for day then hit the four stair, but now I think this one underground parking lot with ledges nearby has replaced it as the go-to over the years).
Took note of your dates just in case but honestly am completely unable to predict the next time I'll be in Paris right now. Either way, hope you enjoy!
