One of the most unique river experiences in Montana is the Smith River. It is a multiday float trip with limited access, meaning you get to enjoy beautiful scenery and good fishing in relative peace and quiet. Launch dates for the Smith are chosen via a lottery system, and you have to apply ahead of time. The deadline for applications is tomorrow, so don't delay if you haven't already applied!
You can send in a paper application or apply online. Get more information on how to apply on the Smith River State Park website here. This is one of those experiences that every fisherman should enjoy at least once!
