FATMAP difficulty grade
This peak is one of the more accessible in the Sawtooth Range, thanks to the Sawtooth Lake trail and a relatively mellow route to the summit from there.
The climb is typically done within a day, but camping at Sawtooth Lake or Alpine Lake makes a relaxed alternative.
Keep in mind that this area is very popular for day hiking and backpacking in the summer. Once atop Alpine Peak you’ll find a daunting panorama of Sawtooth Peaks, plus of course an unbeatable view down to the lake and across at the majestic Mount Reagan.
In the other direction you can see the town of Stanley down by the Salmon River.
Start from the Iron Creek Trailhead and follow the well-traveled trail to Sawtooth Lake.
The trail continues along the lake’s east shore, and as you follow this look up to find your route on the mountain’s west face.
There is no trail and maybe not a detectable climbers path either, so just pick a gully that looks reasonable and find the path of least resistance.
The climb should not involve anything tougher than Class 3, and serious exposure should be avoidable. By mid July you can ascend on rock and scree rather than snow, but the scree will likely become very steep and loose near the summit ridge.
If you top the ridge anywhere shy of the summit, expect to scramble through ledges and blocks to traverse the rest of the way.
Beware of loose rock.
On the descent you might enjoy some scree skiing or glissading, depending on conditions and the route you choose. Sources: https://idahosummits.com/alpine/alpine.htm https://www.peakbagger.com/climber/ascent.aspx?aid=1219
