North Bass Trail

North Bass Trail is a 13.5-mile, one-way route from Swamp Point to the Colorado River, losing about 5,300 feet as it drops through White Creek and Shinumo Creek. It is a remote, exceptionally strenuous backcountry hike for people with serious canyon experience. Allow about 20 hours of walking, usually divided over several days. The river is the end of the mapped trail, not a road exit; unless you have an arranged river pickup, plan the return too. A four-day out-and-back is a sensible itinerary, and overnight camping below the rim requires a permit.

Swamp Point is reached by rough Forest Service roads from the north; that approach is easier than driving in through Point Sublime and Kanabownits Roads. Bring a Kaibab National Forest map. Swamp Ridge Road is seasonally gated after the first snow until crews clear downed trees, and opening dates vary. The first mile switchbacks about 800 feet down to Muav Saddle. At the junction, take the left branch for North Bass; the middle route climbs toward Powell Plateau and the right branch goes to an old patrol cabin. The trail then skirts the pale Coconino cliffs to Queen Anne Spring, which is seasonal.

Below the spring, the route gets brushy and can disappear into White Creek's rocky bed. Cairns mark bypasses around waterfalls and pour-offs, but they take attention to follow. Near mile 4.5, a cairned traverse crosses four drainages along the Redwall before a steep, loose descent drops back to the creek. This is not a place to hurry or count on continuous tread. This is a stretch to give time, not rush or leave for tired, late-day route-finding.

After White Creek, the route climbs onto the Tonto Platform for a couple of miles, then descends to Shinumo Creek near the White Creek confluence, about 10.3 miles from Swamp Point. From there, expect several creek crossings as you follow the water downstream. Bass Camp, the remains of William Wallace Bass's tourist camp, is around mile 12. The final leg leaves the creek, climbs to a saddle, and drops to a broad sandy beach at the Colorado River.

Bass built this trail around 1899–1901 as a continuation of his South Bass route, first for mining and later for tourist trips. His camp below the rim had a garden and orchard; mining tools and household pieces remain near the creek. At the river, stacked stone and cable strands mark the old ferry landing. Leave the artifacts where they are. The 1925 Snowshoe Cabin at Muav Saddle is a nearby historic landmark on the cabin branch, not the North Bass route itself.

The upper route moves through North Rim forest and scrub, then cuts across the Coconino Sandstone, Redwall, Bright Angel Shale, Tapeats and Shinumo rock layers. Muav Saddle formed where a fault weakened the rock and helped erosion cut the notch. Lower down, White Creek's bare rock gives way to the greener Shinumo drainage and its cottonwood shade. At river camps, ringtail cats may get into food, so store it securely.
