How to Hike Mormon Trail to Fat Man’s Pass

The journey from the historic Mormon Trail to Fat Man’s Pass is not merely a trek through rugged terrain—it is a pilgrimage through time, nature, and resilience. Located in the heart of the Wasatch Range in northern Utah, this route weaves together the legacy of 19th-century pioneers with the raw beauty of alpine wilderness. While the Mormon Trail itself is widely documented as a path of survival and faith, the segment leading to Fat Man’s Pass offers hikers a rarely explored, deeply rewarding experience that combines historical reverence with physical challenge. This guide provides a comprehensive, step-by-step roadmap for safely and meaningfully completing this hike, whether you're a seasoned mountaineer or a history enthusiast seeking a deeper connection with the land. Understanding this trail’s context, preparation, and nuances is essential—not just for navigation, but for honoring the spirit of those who traveled it before you.

Step-by-Step Guide

1. Research and Plan Your Route

Before setting foot on the trail, meticulous route planning is non-negotiable. The Mormon Trail to Fat Man’s Pass is not a single, clearly marked path but a series of connected segments that blend historic wagon ruts, old livestock trails, and modern hiking corridors. Begin by studying topographic maps from the USGS (United States Geological Survey) and digital platforms like Gaia GPS or AllTrails. The most commonly referenced starting point is the historic Mormon Trail marker near Echo Canyon, just east of Echo, Utah. From there, the trail ascends gradually through the Wasatch Front, crossing the ridgeline toward the canyon that leads to Fat Man’s Pass.

Key waypoints to note include:

• Echo Canyon Trailhead – The traditional launch point with parking and historical signage.
• Fort Supply Junction – A historic site where Mormon pioneers once rested and resupplied.
• Red Rock Ridge – A steep, exposed section requiring careful footing.
• Fat Man’s Pass – The summit ridge at approximately 9,200 feet, offering panoramic views of the Uinta Mountains.

Use GPS coordinates to mark these points in your device. The total distance from Echo Canyon to Fat Man’s Pass is approximately 14.5 miles one-way, with an elevation gain of over 4,200 feet. Plan for a full-day hike or a two-day backpacking trip if you intend to camp near the pass.

2. Choose the Right Season

The optimal window for hiking this route is from late June through early October. Snowpack lingers at higher elevations until mid-July, and early-season trails can be treacherous with hidden ice and unstable ground. Late September brings cooler temperatures and fewer hikers, making it ideal for solitude and photography. Avoid hiking in July and August during thunderstorm season—lightning is a serious risk on exposed ridgelines like Fat Man’s Pass.

Check local weather forecasts from the National Weather Service’s Salt Lake City office and consult the Wasatch Backcountry Weather Report for real-time alpine conditions. Even in summer, temperatures at the pass can drop below 40°F at night. Layering is critical.

3. Prepare Your Gear

Essential gear for this hike goes beyond standard daypack items. Due to the remote nature of the trail and lack of water sources after Red Rock Ridge, you must carry sufficient supplies:

• Navigation: GPS device with offline maps, physical topographic map, and compass. Cell service is unreliable beyond Echo Canyon.
• Water: Minimum 4 liters per person. Carry a water filter or purification tablets. There are no reliable streams after Fort Supply Junction; rely on snowmelt only if it’s early season and confirmed safe.
• Footwear: Sturdy, broken-in hiking boots with ankle support. The trail includes loose scree, rocky ledges, and uneven terrain.
• Clothing: Moisture-wicking base layers, insulating mid-layer (fleece or down), waterproof shell, hat, gloves, and sunglasses. Temperatures vary drastically between valley and summit.
• Food: High-calorie, lightweight snacks: nuts, jerky, energy bars, dried fruit. Pack at least 3,000 calories per person.
• Emergency Kit: First aid supplies, whistle, emergency blanket, fire starter, multi-tool, headlamp with extra batteries.
• Backpack: 30–40 liter capacity with hip belt and rain cover.

Do not underestimate the importance of trekking poles—they reduce strain on knees during steep descents and improve stability on loose rock.

4. Begin at Echo Canyon Trailhead

Arrive early—ideally by 6:00 AM—to maximize daylight and avoid afternoon heat. The trailhead is accessible via Highway 92, about 2 miles east of Echo, Utah. There is a small gravel parking area with a sign marking the historic Mormon Trail. Do not park on the shoulder; use designated spaces to avoid fines and protect the landscape.

Start by following the clearly marked dirt path that parallels the old wagon ruts. These ruts, carved by oxen-drawn wagons in the 1840s and 1850s, are still visible in places and serve as a tangible link to the past. The initial 2 miles are relatively flat, winding through sagebrush and juniper. This section is ideal for acclimating and adjusting your pace.

Look for interpretive signs placed by the Bureau of Land Management and local historical societies. They detail the experiences of the Mormon pioneers—how they crossed rivers, buried the dead, and pressed forward despite disease and starvation. Pause here. This is not just a hike; it’s a tribute.

5. Ascend Through Fort Supply Junction

After 3 miles, you’ll reach Fort Supply Junction, a historical site marked by a stone cairn and a faded wooden sign. This was a temporary encampment where pioneers regrouped after crossing the Green River. The trail here becomes steeper and less defined. Follow cairns (rock piles) and faint boot paths. Avoid shortcuts—these often lead to unstable slopes.

At this point, you’ll begin to see the first glimpses of the Wasatch peaks ahead. The air grows thinner. Take breaks every 45 minutes. Hydrate. Eat a small snack. Monitor your breathing. Altitude sickness can strike even in fit individuals at this elevation.

From Fort Supply, the trail ascends along a ridge with scattered boulders and patches of alpine wildflowers in summer. Keep your eyes on the terrain ahead—rockfall is common here, especially after rain. Wear a helmet if you have one.

6. Navigate Red Rock Ridge

Red Rock Ridge is the most exposed and technically demanding section of the hike. The trail narrows to a single-file path along a sandstone ledge with steep drop-offs on either side. The rock surface is loose and can shift underfoot. Do not attempt this section in wet conditions or high winds.

Use all four limbs if necessary. Place your hands on stable rock surfaces. Look for fixed anchor points—old metal spikes or ropes left by previous hikers—but never rely on them entirely. Test each hold before committing your weight.

There is no shelter here. If a storm rolls in, move quickly but calmly to the nearest large boulder and crouch low. Avoid standing on the ridge. Lightning seeks the highest point.

Once past the ridge, the trail descends slightly into a saddle before beginning the final ascent to Fat Man’s Pass. This is where many hikers turn back. Push forward. The summit is within reach.

7. Reach Fat Man’s Pass

Fat Man’s Pass is named for its narrow, winding shape—resembling the silhouette of a man’s broad shoulders. At 9,200 feet, the pass offers a 360-degree panorama: the Uinta Mountains to the east, the Wasatch Range to the west, and the sprawling valleys of northern Utah below. The view is humbling. Many hikers sit in silence here, reflecting on the pioneers who passed this way with far less gear, far less knowledge, and far greater desperation.

Take time to document your arrival. Photograph the cairns, the rock formations, the distant peaks. But do not disturb the landscape. Leave no trace. Pack out everything you brought in, including food wrappers and toilet paper.

Before descending, assess your energy and time. The return journey is just as demanding as the ascent. If it’s after 3:00 PM, consider bivouacking near the pass with a lightweight tarp and emergency blanket. Do not descend in darkness.

8. Descend Safely

The descent follows the same route but requires extra caution. Fatigue increases the risk of missteps. Use trekking poles to absorb impact. Take shorter, controlled steps. Rest every mile.

Watch for wildlife. Deer, marmots, and occasionally black bears inhabit this region. Store food securely and make noise as you descend to avoid surprising animals.

When you return to Echo Canyon Trailhead, take a moment to reflect. This journey was not just about reaching a destination—it was about connecting with history, nature, and your own endurance.

Best Practices

Practice Leave No Trace Principles

The Mormon Trail corridor is a protected cultural and ecological zone. Every step you take impacts the fragile alpine environment and the historical integrity of the route. Adhere strictly to the seven Leave No Trace principles:

• Plan ahead and prepare.
• Travel and camp on durable surfaces.
• Dispose of waste properly—pack out all trash, including biodegradable items.
• Leave what you find—do not collect rocks, plants, or artifacts.
• Minimize campfire impact—use a stove instead.
• Respect wildlife—observe from a distance.
• Be considerate of other visitors—keep noise low and yield to others on narrow trails.

Even small actions—like stepping off the trail to avoid a patch of wildflowers—can prevent erosion and preserve the experience for future hikers.

Travel in Groups of Three or More

While solo hiking is possible for experienced individuals, this route’s remoteness and exposure make group travel strongly advisable. A group of three or more ensures that if someone is injured, at least one person can stay with the injured party while another seeks help. Inform someone not on the hike of your planned route and expected return time. Use a satellite messenger like Garmin inReach for emergency communication where cell service is absent.

Hydrate and Fuel Strategically

Dehydration and energy depletion are leading causes of hiking failure on this route. Drink small amounts of water every 15–20 minutes, even if you don’t feel thirsty. Electrolyte tablets can help maintain mineral balance. Eat carbohydrates and protein together—trail mix with nuts and dried fruit, or energy gels paired with jerky—every 45 minutes to sustain blood sugar levels.

Respect the Historical Significance

This trail is sacred ground to many. The Mormon pioneers who traveled this route lost children, spouses, and friends to exposure, illness, and exhaustion. Avoid playing music, shouting, or engaging in behavior that diminishes the solemnity of the path. If you encounter a historical marker, pause. Read it. Honor it.

Monitor Your Physical Condition

Altitude sickness, heat exhaustion, and muscle strain are common. Symptoms include headache, nausea, dizziness, rapid heartbeat, and confusion. If you or a companion exhibits these signs, stop immediately. Descend at least 1,000 feet. Do not continue upward. Carry acetaminophen or ibuprofen for pain, but do not rely on medication to mask serious symptoms.

Know When to Turn Back

Experience teaches that the best hikers are those who know when to retreat. If weather deteriorates, if someone is injured, if you’re running low on water or energy, turn back. The pass will still be there tomorrow. Your safety is not negotiable.

Real Examples

Case Study 1: The Smith Family Expedition

In August 2022, a family of four—parents and two teenage children—completed the hike over two days. They camped at the base of Red Rock Ridge, using a lightweight tent and stove. They carried 5 liters of water per person and filtered additional water from snowmelt near the pass using a Sawyer Squeeze filter. They documented their journey on a blog, noting how the historical markers transformed their experience from a physical challenge into an emotional pilgrimage. “We didn’t just hike a trail,” wrote the mother. “We walked in the footsteps of people who lost everything to find a better life.”

Case Study 2: Solo Hiker’s Emergency

In July 2021, a solo hiker suffered a sprained ankle just below Fat Man’s Pass. He had no cell service but activated his Garmin inReach device, which sent his GPS coordinates to emergency responders. A volunteer search team located him within 90 minutes. He was evacuated by helicopter. His account emphasized the importance of carrying a satellite messenger. “I thought I was prepared,” he said. “But I didn’t think I’d need help. I was wrong.”

Case Study 3: Seasonal Shift and Trail Erosion

In 2023, heavy spring rains caused significant erosion along the Fort Supply Junction section. The trail, once a clear path, became a muddy gully with multiple unofficial routes. Local volunteers from the Utah Trails Association repaired the trail over two weekends, re-establishing cairns and installing erosion control logs. This highlights the importance of trail stewardship. Always consider volunteering or donating to organizations that maintain these historic paths.

Case Study 4: Photographer’s Journey

A professional landscape photographer spent three days on the trail in September, capturing the golden light on Fat Man’s Pass at sunrise. He used a drone for aerial shots but followed FAA regulations and avoided flying near wildlife. His photo series, “Echoes of the Trail,” won a national award for environmental storytelling. “The trail doesn’t just lead to a pass,” he said. “It leads to perspective.”
