Rexburg to Island Park is a 50.9 mile point-to-point trail located near Rexburg, Idaho. The trail is primarily used for scenic driving and is accessible from May until November.
I'm from the East Coast so for me, this was an incredibly scenic drive for being on a highway. From Rexburg until you hit Caribou-Targhee National Forest, on a clear day you can see all the way to the Tetons. They loom over miles of undulating grain fields and the view is especially stunning at sunrise. Once you get into the national forest, the drive is forested but with the opportunity to see all kinds of wildlife such as moose and deer.
