Perrine Coulee Falls is a 2 mile out and back trail located near Twin Falls, Idaho that features a waterfall and is rated as moderate. The trail is primarily used for hiking and is accessible year-round.
Nice waterfall with patches of icey snow (early march). Short hike up has excellent view of gorge area. Not that hard or long.
Not really a trail, but still a beautiful waterfall. Especially since it is right off the interstate.
I'm not sure I would call this a trail, but it is a trek on the grade. A narrow road that is heavily travelled. People biking, walking, or driving all need to be mindful of each other and give plenty of space.
We only walked part of it; but was nice.
