Plan a hiking tour with trail selection, time estimation, elevation analysis, and safety assessment for groups of varying fitness levels.
Establish the parameters that constrain trail selection.
Group Fitness Classification:
┌──────────────┬──────────────────────────────────────────────────┐
│ Level │ Capabilities │
├──────────────┼──────────────────────────────────────────────────┤
│ Beginner │ 3-4 hrs walking, <500 m elevation gain, │
│ │ well-marked paths only (SAC T1-T2) │
├──────────────┼──────────────────────────────────────────────────┤
│ Intermediate │ 5-7 hrs walking, 500-1000 m elevation gain, │
│ │ mountain trails with some exposure (SAC T2-T3) │
├──────────────┼──────────────────────────────────────────────────┤
│ Advanced │ 7-10 hrs walking, 1000-1500 m elevation gain, │
│ │ alpine trails, scrambling (SAC T3-T5) │
├──────────────┼──────────────────────────────────────────────────┤
│ Expert │ 10+ hrs, 1500+ m gain, via ferrata, glacier, │
│ │ technical terrain (SAC T5-T6, UIAA I-III) │
└──────────────┴──────────────────────────────────────────────────┘
SAC Hiking Scale Reference:
T1 - Hiking: Well-maintained paths, no exposure
T2 - Mountain hiking: Marked trails, some steep sections
T3 - Demanding: Exposed sections, scree, basic scrambling
T4 - Alpine hiking: Simple scrambling, steep exposed terrain
T5 - Demanding alpine: Challenging scrambling, glacier crossings
T6 - Difficult alpine: Very exposed climbing, technical ice/rock
Document the group's weakest-link fitness level, as this determines the maximum difficulty.
Expected: A clear requirements profile with group level, time budget, elevation tolerance, and any must-include or must-avoid constraints.
On failure: If the group has mixed fitness levels, plan for the weakest member but identify optional extensions for stronger hikers (e.g., a peak side trip while others rest at a hut).
Research and shortlist trails matching the requirements.
Sources for trail data:
sac_scale)For each candidate trail, collect:

└─────────────────────┴──────────────────────────────────────┘
Shortlist 2-3 candidates that fit the requirements plus one easier backup option.
Expected: A shortlist of trail candidates with complete data sheets, all within the group's capability range.
On failure: If no trails match all constraints, relax the least important constraint first (typically distance before difficulty). If trail data is incomplete, note the gaps and plan to verify on-site or contact local tourism offices.
Estimate hiking time using the Swiss Alpine Club (SAC) Munter formula for realistic planning.
Munter Formula:
Time (hours) = (horizontal_km + vertical_km) / pace
Where:
- horizontal_km = trail distance in km
- vertical_km = elevation gain in meters / 100
(each 100 m up counts as 1 km)
- pace = km/h achieved on flat ground
Pace by Fitness Level:
┌──────────────┬────────────────┬──────────────────────────────┐
│ Level │ Pace (km/h) │ Notes │
├──────────────┼────────────────┼──────────────────────────────┤
│ Beginner │ 3.5 │ Includes frequent stops │
│ Intermediate │ 4.0 │ Steady pace, short breaks │
│ Advanced │ 4.5 │ Efficient pace, few breaks │
│ Expert │ 5.0 │ Fast and steady │
│ With kids │ 2.5-3.0 │ Very frequent stops │
│ Heavy pack │ Subtract 0.5 │ Multi-day with full pack │
└──────────────┴────────────────┴──────────────────────────────┘
Descent Adjustment:
- Gentle descent (<20% grade): adds minimal time
- Steep descent (>20% grade): add elevation_loss_m / 200 hours
- Very steep/technical: add elevation_loss_m / 150 hours
Example calculation:
Trail: 12 km distance, 850 m elevation gain, 400 m steep descent
Group: Intermediate (pace = 4.0 km/h)
Ascent component: (12 + 850/100) / 4.0 = (12 + 8.5) / 4.0 = 5.1 hours
Descent component: 400 / 200 = 2.0 hours additional for steep descent
Total estimate: 5.1 + 2.0 = 7.1 hours (round to 7-7.5 hours)
Add breaks: +30 min lunch, +15 min x 3 short breaks = +75 min
Total with breaks: approximately 8.5 hours trailhead to trailhead
Expected: Time estimates for each trail candidate, including break time. Estimates should be conservative (better to arrive early than to hike in darkness).
On failure: If calculated times exceed the available daylight, the route is too long. Either shorten it (find a closer end point or skip a section via transport) or split into two days. If the group is untested, use the beginner pace for the first day and adjust based on actual performance.
Evaluate objective and subjective hazards for the selected route.

Overall Safety Rating:
GREEN - All factors favorable, proceed as planned
YELLOW - One or more concerns, proceed with extra caution and backup plan
RED - Significant hazards present, postpone or choose alternative route
Expected: A completed safety assessment with all hazards rated and mitigations documented. An overall GREEN/YELLOW/RED rating for the go/no-go decision.
On failure: If the assessment yields RED for the primary route, switch to the backup option from Step 2. If all options are RED (e.g., severe weather forecast), postpone the hike. Never override a RED safety rating for schedule convenience.
Organize practical details for the hiking day or multi-day tour.
Logistics Checklist:
┌──────────────────────┬──────────────────────────────────────────┐
│ Category │ Details to confirm │
├──────────────────────┼──────────────────────────────────────────┤
│ Trailhead access │ Driving directions, parking, bus/train │
│ Hut reservations │ Booking required? Half-board available? │

│ Emergency contacts │ Mountain rescue #, local emergency │
│ Map and navigation │ Paper map, offline GPS, waypoints loaded │
│ Group communication │ Meeting points if group separates │
│ Return transport │ Last bus/train time from endpoint │
│ Parking shuttle │ If start != end, how to retrieve car │
└──────────────────────┴──────────────────────────────────────────┘
For multi-day tours:
Expected: All logistics confirmed or flagged as pending. Hut reservations made. Transport to/from trailhead arranged. Emergency plan documented.
On failure: If huts are full, check for nearby alternatives (bivouacs, camping, lower huts with longer approach). If trailhead access is complicated (e.g., closed road), arrange alternative transport or adjust the starting point.
Compile everything into a complete hiking plan document.
Hiking Plan Document Structure:
1. Summary
- Route name, dates, total distance/elevation
- Group members and emergency contacts
- Overall difficulty and safety rating
2. Day-by-Day Itinerary
- Start/end points with times
- Distance, elevation gain/loss, estimated time
- Key waypoints and navigation notes
- Water sources and meal plans
- Escape route options
3. Safety Information
- Weather forecast (to be updated day-of)
- Known hazards and mitigations
- Turn-around time and triggers
- Emergency procedures and contacts
4. Logistics
- Transport arrangements
- Accommodation bookings
- Gear checklist reference
5. Maps
- Overview map with all days
- Elevation profile for each day
Expected: A complete hiking plan that can be shared with all participants and left with an emergency contact. The plan should be actionable without additional research.
On failure: If the plan has gaps that cannot be filled before departure, document them clearly and assign someone to resolve each item. Critical safety gaps (no escape route identified, no weather check plan) must be resolved before departure.
