Why hiking difficulty is personal
Workload
Distance, ascent and pack weight shape the physical effort and likely duration.
Terrain
Rough, steep or exposed ground changes pace, concentration and consequence.
Resilience
Fitness, experience, navigation confidence and group pace affect how manageable the same route feels.
This is not a mountain-safety rating. Check official trail status, weather, daylight, hazards, access restrictions and rescue guidance, and turn back when conditions or ability require it.
