Mary Jemison Trail
Mary Jemison Trail is a forested route named for Mary Jemison linking the southern park area with quieter woodland terrain. The mileage matters, but the real character of the route comes from wooded tread, rolling hills, roots, and seasonal mud. Plan the entire outing—parking, trailhead preparation, movement time, breaks, changing conditions, and the return—rather than treating the destination as the only part of the hike.
The details below turn the route into a usable day plan. They explain the trailhead, major landmarks, permits, likely trouble points, pace, gear, and a shorter objective. Operating rules and conditions can change, so compare the plan with the managing agency's current alert before leaving for South park trail network.

Trail Conditions and Effort
The route is best understood as out and back, with wooded tread, rolling hills, roots, and seasonal mud. Those details affect speed, footwear, balance, water use, and whether every member of the group can complete the same movement on the return. A short trail with chains, deep sand, submerged rocks, ice, or steep stone steps can require more judgment than a longer smooth path.
Route walkthrough
Trailhead and First Section
Begin at South park trail network and confirm the correct signed route, current conditions, and your turnaround time before leaving the developed area. Pause at the end of this stage to compare actual time, water use, weather, and group condition with the plan. Confirm the next junction before moving, because a familiar-looking trail or a line of footprints can lead away from the intended route.
Main Route
Follow the official trail through wooded tread, rolling hills, roots, and seasonal mud, pausing at junctions and viewpoints to confirm the return route. Pause at the end of this stage to compare actual time, water use, weather, and group condition with the plan. Confirm the next junction before moving, because a familiar-looking trail or a line of footprints can lead away from the intended route.
Turnaround and Return
Trailhead access and arrival
Check current trail and road status. Some gorge-edge sections close seasonally, and most linear trail lengths must be doubled for an out-and-back.
The starting point is South park trail network. Save the trailhead, route map, and permit proof offline. Arrive with enough time to solve a full lot or shuttle wait without rushing. Never invent roadside parking, cross a closed gate, or start late because the drive was longer than expected. A full access point is a reason to use the backup route selected at home.
Permit, services, and current rules
No separate day-hike permit is normally required; seasonal vehicle entry fees may apply.
Plan for the Return Trip
Outward leg
Return leg
Turn around at the first signed junction if the return distance, weather, or trail markings become uncertain. The return can be uphill, hotter, darker, more crowded, harder on tired knees, or slower through water and loose ground. Keep food, water, attention, and daylight in reserve. Make the turnaround decision before anyone is depleted enough to argue for continuing.
Season, weather, and daily timing
Hazards to manage deliberately
The main concerns are gorge edges, steep stairs, mud, ice, falling branches, seasonal closures, and long linear routes. Name the hazards before starting so every person understands what would trigger a turnaround.
- Footing: Slow down on wet rock, loose stone, roots, sand, snow, ice, or submerged surfaces. Use poles or traction only when practiced and appropriate.
- Weather: Leave ridges, open summits, river corridors, and slot canyons before storms arrive. Thunder, rapidly rising water, or sudden wind is an action signal.
- Heat and cold: Protect skin, carry layers, and watch for headache, nausea, confusion, shivering, or declining coordination. Do not wait for collapse.
- Navigation: Confirm every important junction on the return. Crowds, footprints, and a phone dot are not substitutes for an offline map.
- Wildlife: Give animals space, secure food, control pets where allowed, and follow local bear, bison, goat, snake, or nesting-season guidance.
- Group management: Stay together, place a capable adult at the rear, and never leave a struggling person alone so others can reach the destination.
What to carry
- Official route map, offline navigation, charged phone, cable, and backup battery.
- Enough water for the full route, current conditions, and an unexpected delay.
- Food for the planned time plus a reserve portion kept for the return.
- Weather layers, rain or wind shell, hat, sunglasses, sunscreen, and dry insulation where needed.
- Headlamp, first aid, blister care, personal medication, whistle, and emergency shelter.
- Footwear and route-specific equipment for wooded tread, rolling hills, roots, and seasonal mud.
Who should choose another hike
Leave enough margin to handle the part of the day that was not in the itinerary.
