There is overnight camping at the RV Village and that would be the closest to the trails. For overnight camping on LOLO pass there are a couple of overnight camping areas available. Cheaper but not as convenient. I believe reservations are definitely required at the RV Village. But it is much closer to the trails.
Lolo pass is about the closest legal camping area, it's about a 20 minute drive that you can take 26 or the road to sandy Ridge to.
