Lost River Mountain Super Gully Trail

The Lost River Mountain Super Gully Trail is a challenging hike. While the Komoot tour suggests a duration of approximately 4 hours and 30 minutes, real-world experiences often range from 5 to 9.5 hours for a round trip, depending on conditions and hiker pace. It covers about 7.2 km (4.5 miles) with significant elevation gain.

This trail is rated as difficult. It features a relentlessly steep uphill climb from the start, with sections of loose scree, talus, and potentially snow and ice depending on the season. The upper gully can be particularly challenging with 'treadmill scree' where every step can result in backward sliding. The summit ridge may also involve considerable exposure.

The terrain is varied and demanding. It begins with a steep ascent, often above the treeline. The prominent Super Gulley itself starts fairly mellow but steepens considerably. You'll encounter loose rocks, scree, and talus fields, which can be 'extremely loose and rotten'. In spring, the gully is often snow-covered, requiring snow climbing techniques. The summit ridge can be a mix of snowy and rocky sections, sometimes described as a 'knife edge ridge'.

Hikers are rewarded with expansive high-alpine scenery. Key features include the distinctive Super Gulley, the 'stadium of the gods' section with its unique cliff bands, and the panoramic views from the summit of Lost River Mountain. From the top, you can see the surrounding Lost River Valley, the Lemhi Range, and other Idaho 12,000-foot peaks like Mount Borah and Mount McCaleb.

The best time depends on your preferred challenge. For a summer ascent, expect loose scree and talus, typically from late June to early October. For a snow climb, spring (May to early June) is popular, but requires snow climbing skills and gear. Early season hikes might also offer views of waterfalls.

Given the trail's difficulty and varied conditions, essential gear includes sturdy hiking boots, trekking poles (especially for scree surfing on descent), and plenty of water. If hiking in spring or early summer, crampons and an ice axe are often necessary for snow sections. A headlamp is recommended for early morning starts or if you anticipate a long day.

The trail typically starts at the Lost River Mountain Trailhead. Information on specific parking availability is best checked with local forest service resources, but generally, there is parking at the trailhead for this remote area.

The Lost River Mountain Super Gully Trail is located within the Salmon-Challis National Forest. Generally, there are no specific permits required for day hiking, nor are there entrance fees for the forest itself. However, it's always wise to check the latest regulations with the Salmon-Challis National Forest service before your trip, especially for group sizes or specific activities.

While many trails in national forests are dog-friendly, the extreme difficulty and rugged terrain of the Lost River Mountain Super Gully Trail make it unsuitable for most dogs. The loose scree, steep snow, and potential exposure could be dangerous for pets. If you do bring a dog, ensure they are experienced with challenging alpine conditions and always keep them on a leash.

No, the Lost River Mountain Super Gully Trail is not suitable for beginners or families with young children. It is considered a very challenging and difficult hike, requiring significant physical fitness, experience with steep terrain, and potentially snow climbing skills. The relentless steepness, loose scree, and exposure make it an advanced route.

Yes, for experienced hikers, 'scree surfing' is a common and rapid way to descend sections of the gully. This involves sliding down the loose scree fields. It requires good balance, appropriate footwear, and often trekking poles for stability. It can be exhilarating but also challenging and potentially risky if not done carefully.
