Payette River Scenic Byway is a 112 mile trail located near Boise, ID. The trail is primarily used for scenic driving and is accessible year-round.
Traveled this shuttling cars on a river trip years ago. Beautiful drive
I have driven this hwy countless times and no matter the season, the views are breathtaking. Some of my favorite in idaho. take your time and watch the road.
If you're heading north towards northern Idaho from the Boise area, definitely take this route (Hwy 55) rather than Hwy 95. Even though 95 may get you there quicker (negligible), this drive is well worth the extra couple minutes. The drive along the Payette gives you a glimpse of world class white water, beautiful forests, and opens up into a beautiful mountain valley.
I've traveled on this scenic byway several times and it's always been very pretty, no matter the season. It's also a fairly long drive, depending on how far you plan on going, so be prepared for anything and watch out for deer and falling rocks along the way.
