Start With the Route, Not a Universal Packing List
Packing needs change with the route's length, terrain, exposure, weather, access rules, water availability, mobile coverage, and distance from help. First confirm the correct trailhead, expected duration for your own pace, return transport, current weather and warnings, daylight, permission or ticket requirements, and whether the responsible authority requires or recommends a guide. A short established walk near town should not be planned in the same way as an unmarked Knuckles or forest route.
