@Yirkl Thanks for reaching out!
Unfortunately it does not look like there is any registered camping available yet. A post last week on their Facebook page indicates they're close to getting the information updated for folks. It does look like they are posting pretty regularly on their Facebook page so that would be where I would check in with them. You can also e-mail them at email@example.com . I hope this helps and that you have an awesome time at Trails Fest this year!
