I'm heading up to Idaho in about a month for 2 weeks of rafting. One of the runs I'm looking to float is the Teton Narrows below Felt Dam. I know it's a truely epic put in for a raft but am looking for some directions to where the "trail" down starts and the roads I'd take to get there. Have not had any luck on specifics yet. Can anyone help or even point me in the right direction for beta like that? It would be much appreciated.
