One of the park's most difficult rim-to-river trails. Descend 9 miles with 4,650 feet of elevation loss and zero water sources—nothing but exposure, heat, and your grit. This barely-maintained route earns the name 'Furnace Flats' for its relentless sun and sparse shade. Expert desert hikers only.
Expert only
Reaching the Colorado River after 9 miles of suffering. The Grand Canyon Supergroup rocks frame the river in colorful striations—rust reds, purples, grays. The only reliable water source. Established campsites on the east bank of Tanner Canyon offer sunrise views of the canyon floor.
• The 75 Mile Creek Saddle (1.6 miles, 1,700 ft descent) is the realistic day-hike turnaround. It's brutal enough and offers canyon views without full commitment. The descent beyond is exposed and dangerously hot. • Upper section is a navigation puzzle. Cairns mark sections but rockslides erase them. Study the Toroweap-to-Coconino Sandstone transition before you start. • River runners call it 'Furnace Flats' because the silt-laden Colorado reflects heat like a mirror. Waterproof sunscreen is mandatory. • Night-hiking the descent is tempting but deadly—loose rock, eroded edges, exposed scrambles. Never attempt the dark descent. • The 1890s pioneers (Franklin French, Seth Tanner) carved this for miners. It's been 'improved' the same way since: barely.
October through March
Not family-friendly. Exposed drop-offs, extreme heat, dehydration hazard, and sustained physical demands make this unsuitable for children or inexperienced hikers. The NPS explicitly states this is 'not a recommended first hike into the canyon.'
Hikers who complete this call it one of the park's most punishing descents—9 miles of relentless exposure, heat, and eroded terrain with zero water sources. Most turn back at the 75 Mile Creek Saddle (1.6 miles). Only experienced desert backcountry hikers attempt the full descent; those who reach the Colorado say it's transformative—but not in a fun way.
Backcountry permit required for camping. Apply online at nps.gov/grca/planyourvisit/backcountry-permit.htm or request in person at the Backcountry Information Center. Tanner Canyon use area (BB9) allows at-large camping. Day-hikes require no permit beyond park entry.
No shuttle required. Private vehicle access to Lipan Point on Desert View Drive (23 miles from South Rim).
This is 'Furnace Flats'—summer temperatures exceed 100°F with near-zero shade. The upper section is steep, narrow, and badly eroded; rockslides have obliterated the original trail, forcing exposed scrambles on unstable ground. Winter ice transforms the slopes into a fall hazard. Monsoon lightning (July-September) strikes the open canyon with nowhere to shelter. The Colorado River, your only water source, is often silt-laden and time-consuming to purify. Hikers pushing beyond the 75 Mile Creek Saddle face increasingly exposed terrain with real drop-offs.
Rooty, steep, and badly eroded. Not accessible. Requires rock scrambling, route-finding through rockslides, and exceptional fitness and desert experience.

Lipan Point offers parking and views. Desert View Market & Deli and Desert View Trading Post (with ice cream) sit 2-5 miles away on Desert View Drive. No water, food, or services at the trailhead. Nearest full services: South Rim Village, 30+ miles away.

Yes. One of the park's most difficult developed trails. Zero water sources, rarely maintained, steep, exposed, and eroded. The NPS explicitly states it's 'not a recommended first hike into the canyon.' Expert desert hikers only.
Bright Angel is maintained, has water sources, and is popular for day-hikes. Tanner is barely maintained, has zero water until the river, and is a serious backcountry expedition. Tanner is several grades harder.
Technically yes—it's 9 miles. Realistically, no. Most turn back at 75 Mile Creek Saddle (1.6 miles). A full descent-and-return is 18+ miles with 9,300 feet elevation change. Budget 12-16 hours minimum. Most hikers aren't that committed.
Minimum 3-4L per person for a day-hike attempt. Drink constantly. The river won't help—it's 9 miles away and purification is time-consuming (30-60 minutes with silt-laden water). Most hikers run out before turning back.
Not without preparation. The eroded upper section is narrow with real exposure. Rockslides cover the original trail. It's safe if you: bring a map, move carefully on loose scree, never hike in darkness, file a trip plan, and never attempt it in summer heat or winter ice.
Yes, for backcountry camping. Apply online at nps.gov/grca/planyourvisit/backcountry-permit.htm or in person at the Backcountry Information Center. Day-hikes need no permit beyond the $20-35 park entry fee.
