Steepest Peak In Each Idaho County by Tim Worth

This list is shows the steepest peak in each Idaho county, based on calculations explained in the Top 500 Steepest ID Peaks List. A mInimum Prominence of 300 feet is required to be listed. Caribou and Bear counties share Meade Peak as thier steepest peak.

Please note that Bannock Peak is on the Fort Hall Reservation, Peak 2730 is on the Nez Perce Reservation and Peak 6575, Walters Butte and Hawk Benchmark are on private property and not open to the public. I am not familiar with access to several other peaks on the list. Thus, the fact that the rest of the peaks are on public land does not guarantee that access will always be straightforward. Always make there is public access before attempting an ascent. Also, climbing was banned on the Twin Sisters in 1998 by the National Park Service.

The “Rank” figure on the left is the peak’s steepness rank out of all 5856 ID summits. Information provided by Tim Worth.

The LoJ link for each peak will take you to the Lists of John website. The IACG Link will take you the peak page on this site. If the peak does not have a page on this site, clicking on the peak’s name will take you the LoJ page. You can also use the search box on this page. Note, as of yet, not all of these peaks have pages on this site or recorded ascents on LoJ.
