Access
Access Peak 6300 from Middle Fork Boise River Road and Slide Gulch Road [(C)(1) on Page 154]. Follow the Slide Gulch Road southeast from the Middle Fork Boise River Road to the first pass, which sits between Slide Gulch and Elk Creek. There is room for two vehicles to park on the pass.
Northeast Ridge, Class 2
From the pass, follow the wandering ridge line northeast and then southeast to the summit. Expect to work your way through brush in a few spots. The ridge has some ups and downs. When you reach the summit of Peak 6300, you will gain nearly 2,000 feet of elevation in 2.5 miles. Class 2. USGS Twin Springs
Start out on the south side of a fence line that runs up the ridge. This shot was taken from roughly 250 vertical feet above the pass. Peak 5424 is in the background, right of center.
As you ascend higher, you eventually see the summit.
The summit is guarded by two [lower] false summits. You can either go over them or side hill around them without difficulty.
Peak 6300 and Peak 5440 Loop
From Peak 6300, follow the connecting ridge over to Peak 5440. The only drawback of our walk was the need to hike 0.6 miles up the road to the pass where we started our hike.

Access
Park at a sharp bend in FSR-213/Slide Gulch Road on the south side of Peak 5453 at 4,295 feet and 43°37’56.8”N, 115°42’38.6”W. This bend is 0.7 miles north-northwest of the Lopez “Cattle Guard” launch point, which is 1.6 miles northeast of the FSR-221/FSR-213 road junction.
Southwest Shoulder/West Rib, Class 2
The Descent
From the summit, return northwest then west and skirt underneath Point 6086. This side-hilling is in reasonable veg and went pretty quickly. Reach the [obvious] magnificent southwest shoulder by dropping to cross a dry gully then angling 25 feet up to gain the crest of the shoulder. Once on the crest of this shoulder, follow it southwest then west on a spur to descend right down to the road bend.
The southwest shoulder has some thick sagebrush and not as many lanes/gaps/game trails as the northwest ridge but it also has no ups and downs. The west rib is fast and easy thanks to docile sagebrush, leafy veg, and dirt/gravel with gaps/lanes. Descend a final fast, steep section in leafy veg to reach a forested gully. Once in the gully, head left/southwest to quickly reach the road at the sharp bend. This is a shorter
