No, the Warner Route is an extremely challenging and strenuous hike, reserved for experienced hikers. It features very steep, rough terrain with loose gravel, rocks, and boulders, and includes significant scrambling with class 2 and 3 sections. The descent drops over 2,700 feet in a short distance, often exceeding 45-degree angles. It is considered one of the most demanding routes into Black Canyon of the Gunnison National Park.
The terrain is exceptionally steep and rugged. You'll encounter loose gravel, rocks, boulders, hardpacked dirt, and tree roots. Expect significant scrambling and sections that feel more like climbing down than walking. The route can be slippery due to loose rocks, and the path becomes faint and difficult to navigate, especially the last mile through a boulder field.
Due to its extreme difficulty and ruggedness, the National Park Service recommends planning for an overnight trip. While the tour data suggests a duration of around 5 hours, this is for the descent only and does not account for the return ascent or time spent at the bottom. Most hikers find it too strenuous for a single day round trip.
The Warner Route begins near the Warner Point Nature Trail. There is parking available at the trailhead, which is located within Black Canyon of the Gunnison National Park.
Yes, a wilderness use permit is mandatory for hiking the Warner Route. You must obtain this permit and attend a safety briefing before embarking on your hike. Permits are limited to a small number each day, so it's advisable to plan ahead.
Unlike some other routes into the canyon, a restroom facility is available at the bottom of the Warner Route, near the Gunnison River. However, there are no other facilities or water sources along the trail itself.
The Warner Route is popular with anglers, particularly during the Salmonfly hatch. Generally, spring and fall offer more moderate temperatures, which are crucial for such a strenuous hike. Summer can be very hot in the canyon, and winter conditions would add significant hazards due to ice and snow on the steep terrain.
As you descend, you'll be rewarded with stunning views of the narrow-walled gorge and the Gunnison River at the canyon's bottom. The initial section, which overlaps with the Warner Point Nature Trail, offers breathtaking panoramic views of the Black Canyon, the Gunnison River, and distant sights of the San Juan Range and the West Elk Mountains.
Given the extreme difficulty, unmaintained nature, and significant scrambling involved, the Warner Route is generally not recommended for dogs. The terrain is very rough and could be dangerous for pets. Always check current park regulations regarding pets on trails within Black Canyon of the Gunnison National Park.
Yes, beyond the mandatory wilderness permit for routes like Warner, hikers should be aware of general park regulations. These include practicing Leave No Trace principles, carrying out all trash, and being prepared for self-rescue. Always check the official National Park Service website for the most current rules and safety information before your visit.
Yes, the route also passes through sections of the Warner Point Nature Trail.
