Description
Tucked in the Boise National Forest near Mores Creek Summit (Idaho Hwy 21) in Boise County, Sunset Mountain Lookout (7,869 ft) is a rewarding high-country detour for adventure motorcycle riders.
The staffed R-6 fire lookout tower, built in 1958 atop an older base, offers panoramic views of the Boise Mountains, North Fork Boise River country, and distant Sawtooths. Dual-sport and ADV riders tackle the rough, steep Forest Road #316 (some sections challenging with downed trees or exposure) from the summit parking area for a leg-stretch, photos, and epic vistas before rejoining backroads toward Idaho City or Lowman. Best in dry summer/fall—respect active fire lookout operations, pack in/pack out, and ride safe.

2 Check-Ins
So the first time up this on my 690 I got stopped by a downed tree. Then, Chatty and I rode to the top with our e-MTBs on Thursday the 11th. Then today (13th) I got up there with my 690. So here's the MTB pic AND the 690 pic. As previously stated in my first post (since deleted) I'm glad I rode my 690 although I have done this ride a few times on my BMW. I think Chatty gave this a 3.5 on a big bike...I'd concur, and add that there are one or two tricky sections that I thought were 3.5s on my 690, including a tricky lefthand hairpin about 3/4 of the way to the top. Finally, this is a really fun ride on an eMTB!! Highly recommended!
I'm counting this even though we were on eMTBs. John (FW190) was not so sure.
The road is open! It's probably a 3.5 on a big bike, especially going back down. 3 on a regular bike because of some of the ruts. 2.5 on a dirt bike.
