The standard pre-hike checklist is an inventory: boots, pack, map, snacks, water, first aid kit. These items matter. But a hiker who ticks every box on the inventory and has answered none of the situational questions — about the weather, the route, the group’s capability, the communication plan — has completed the easy part of pre-hike preparation and skipped the hard part.

The serious hiking accidents that are preceded by no equipment failure almost always involved a decision made before the walk started that was not adequately examined. The route that was too long for the available daylight. The group member whose fitness didn’t match the grade. The weather that was checked at the valley, not at the summit. The emergency contact who didn’t know they were an emergency contact.

This checklist addresses both categories — the inventory and the decisions — in the sequence they should be addressed.

Stage 1: Route Assessment (Day Before)

Basic route metrics

• Total distance: realistic estimate including approach to trailhead and any detours
• Total elevation gain and loss: gain tells you cardiovascular demand; loss tells you knee and ankle demand; these are different and both matter
• Estimated time: use the Naismith Rule as a base (5km/hour on flat + 30 minutes per 300m of ascent) and add 25–50% for your group, terrain and pack weight; the guidebook time is an average for fit hikers with light packs in good conditions
• Technical sections: does the route include any sections requiring scrambling, fixed ropes, exposed traverses or creek crossings? Does everyone in the group have the skills for these?
• Escape routes and turnaround points: at what point on the route is a turnaround still possible? Where are the safe bail-out options?

Weather assessment

• Check the mountain-specific forecast for the route’s maximum altitude — not the valley town. Sources: MeteoSwiss, ZAMG, Météo France bulletin montagne, bergfex.at, yr.no (Norway/Scandinavia)
• What is the forecast temperature at the highest point? Wind speed?
• Afternoon thunderstorm probability? On any route above 2,000m with convective potential, plan to be below exposed terrain by noon
• Any severe weather warnings for the route’s region? (AlertSwiss, DWD Warnwetter, Meteoalarm EU)

Group capability assessment

• What is the least fit / least experienced member’s capability in the expected conditions? The route ceiling is their ceiling, not the group average
• Does anyone have a relevant medical condition — knee problems, altitude sensitivity, heat intolerance, medication that affects performance?
• Has everyone hiked at this grade before, or is this an upgrade in difficulty?

Stage 2: Communication Plan (Day Before)

An emergency contact who doesn’t know they’re an emergency contact is not an emergency contact. The communication plan must be explicitly established, not assumed:

• Designate a specific person as your emergency contact — not “my family knows roughly where I am”
• Tell them specifically: the trailhead name and location, the route or summit name, your planned return time, the number to call if you haven’t checked in by return time + 2 hours (the local mountain rescue: 140 in Austria, 1414 in Switzerland, 112 everywhere in the EU)
• Check in protocol: agree whether you’ll call at the summit, at the trailhead return, or by a specific time; make it a two-way agreement, not a passive assumption
• Vehicle information: tell them the make, colour and registration of the car at the trailhead — rescue teams use this to confirm a group has not returned

Stage 3: Equipment Check (Morning Of)

Navigation

• Physical map of the route area at 1:25,000 scale
• Compass (checked against a known bearing)
• Phone: fully charged, offline map downloaded and route loaded, emergency contact saved, location sharing enabled with emergency contact
• Power bank (charged) if a full day’s navigation will strain battery

Clothing system

• Base layer: merino or synthetic — no cotton
• Mid layer: fleece or down jacket; easily accessible in pack top or side pocket
• Shell: waterproof and windproof; hood functional; in pack, not at home “because the forecast is good”
• Hat and gloves: even in summer above 2,000m; summit wind and unexpected weather make these from optional to essential within minutes
• Spare socks (for multi-day or long days)

Sustenance

• Water: minimum 1.5 litres per person for a half-day; 2.5–3 litres for a full mountain day; know where water sources are on the route if relying on refills
• Food: sufficient calories for the estimated duration plus 20% emergency reserve; don’t rely on hut availability as your primary food plan
• Electrolyte supplement: for any walk over 3 hours in warm conditions

Safety and emergency

• First aid kit (appropriate to route length and technical difficulty)
• Emergency bivouac bag (foil or reinforced; top pocket of pack)
• Headlamp with fresh or tested batteries
• Whistle (attached to pack or person, not buried inside)
• Satellite communicator or PLB (for any route beyond reliable mobile signal)
• Sun protection: SPF 50+, sunglasses (appropriate category for altitude), lip balm

Technical equipment (route-specific)

• Crampons or microspikes if snow or ice is possible
• Ice axe if self-arrest terrain is possible
• Via ferrata set if any Klettersteig sections
• Trekking poles (winter baskets if snow)
• Harness and helmet (for any technical route)

Stage 4: Trailhead Go/No-Go (On The Day)

The trailhead is the last decision point before the mountain. These questions should produce a genuine go or no-go assessment — not a rubber stamp on a decision already made:

• Does the actual sky match the forecast? Unexpected cloud, building cumulus by 8am, or a barometric drop between yesterday and this morning are all reasons to reassess
• What do local sources say? The hut warden who answered the phone yesterday; the other hikers who came down the route this morning; the tourist office trail conditions update — these are more current than the forecast
• Is everyone genuinely ready? Someone who slept badly, has a developing illness or is already uncomfortable at the trailhead will not improve on the mountain. A group member who is not ready is a group member who should not go — or a route that needs to be changed to match their actual state
• Is the turnaround time agreed? State it out loud. Make it a contract. Write it on a visible piece of paper.

Stage 5: Ongoing Trail Assessment

The checklist doesn’t end at the trailhead. The conditions on the mountain are not the conditions in the forecast, and the group’s state at hour 5 is not their state at hour 1. The questions that should be running continuously throughout the day:

• Are we on time? If behind schedule, what does that mean for our descent and return time?
• Is the weather tracking the forecast, or diverging from it?
• Is everyone still physically and psychologically in the same condition they started in?
• Has anything changed in the terrain that we didn’t expect — snow conditions, trail quality, technical difficulty?
• What is our current go/no-go assessment? Would we start this route now, from where we currently are, with the information we now have?

That last question is the most powerful ongoing assessment tool in mountain safety. It strips away the momentum and commitment of a day already in progress and forces a fresh evaluation. If the answer is “probably not” — the turnaround conversation should happen immediately, not at the next col or the next waypoint or the summit that is now visible above you.
