South Fork of The Snake
The South Fork is a 64-mile stretch of the Snake River in southeast Idaho. This portion of river is fast and deep, making it great for float trips, but if you’re looking to access the river by foot, there are plenty of access points near Swan Valley, Irwin, and Heise, ID. Cutthroat, brown, and rainbow trout are the primary fish in this section, with the exception of the occasional whitefish.
The ecosystem of the South Fork is wildly diverse and abundant in food sources for these native and wild fish, resulting in some very healthy catches. Most notably, the brown trout in this section are known to reach trophy level sizes with several 24-inchers being caught each season. If you’re looking to get a local’s take on the area, there are several fishing guides and outfitters who offer guided fishing trips and equipment rentals. These guides can provide valuable insight into the best fishing spots and techniques for catching trout on the South Fork.
