Mount Borah (Borah Peak) rises to 12,668 ft (3,859 m) as Idaho's highest point and a revered challenge for high-altitude climbers and experienced hikers. Located in the Borah Basin above the Sacramento River and near Mackay, it exposes glacial caps, steep scree slopes, and rocky summit ridges. The standard route involves crossing the Helmer Lakes area, ascending flagstone- and shale-lined ledges, and navigating serrated summit. The climb demands route-finding skills, good weather, and minimal technical gear — but rewards include vast alpine vistas, isolation, and a true Idaho milestone. Nearby attractions include The Cathedral and multi-day approaches from Lakes Creek or Trail Creek trailheads. Practical trips combine long day-hikes with high-mountain camping, often with an overnight strategy depending on weather. Weather can change rapidly above treeline; proper alpine skills and preparation are essential for safety and success.
