Lookout Pass straddles the Idaho-Montana border, with a summit at 5,650 feet dropping 1,148 vertical feet to a base at 4,502 feet across 38 runs spread over 540 acres. Terrain splits 47 per cent intermediate, 32 per cent advanced, 13 per cent beginner and 8 per cent expert, with average annual snowfall of roughly 424 inches, among the highest totals of any Idaho ski area. Four lifts, including two double chairs, one quad and one triple chair, serve the mountain, which carries no major multi-resort pass affiliation.

Lookout Pass is one of only a handful of ski areas in the country where skiers can cross a state line on the mountain itself, a novelty tied directly to its position on the historic pass. The resort's substantial snowfall total, well above most of Idaho, has built its reputation as a reliable deep-snow destination despite its comparatively modest acreage. Its lodge and facilities carry genuine historic character rather than modern resort styling.

Scandinavian skiers first used the pass in the early twentieth century, riding Northern Pacific freight cars to reach the terrain, before the area was officially established as an alpine ski area in 1935. A tow rope built the following year from car parts salvaged off an abandoned wreck on the old Yellowstone Highway, now Interstate 90, and on 24 February 1938 the Idaho Ski Club officially opened Lookout Pass Ski Area to the public. Its lodge, built in 1941, is the second-oldest ski lodge in the Pacific Northwest.

The resort's free ski school for children, founded in 1942, has introduced more than 60,000 kids to skiing and snowboarding and is recognised as the longest-running program of its kind. Lookout Pass became a commercial venture in 1991 under Lookout Associates LLC, which has operated and expanded the resort since. Adult daily tickets range from 60 to 75 US dollars, with season passes from 399 dollars, reflecting a historic, community-rooted mountain rather than a high-priced destination resort.
