Hiking alone: the safety checklist for solo hikes

Hiking alone has a freedom of its own. You walk at your pace, stop when you like and hear more of the mountain than you would in a group. The price is easy to name: if something goes wrong, nobody is beside you to fetch help or notice that you are missing.

That is no reason to stay at home. It is a reason to sort out a few things properly beforehand. This checklist walks through a hike from planning to return. It doesn’t replace a course or experience, but it closes the usual gaps.

1. Planning: the right hike for going solo

Choose a route below your limit

What you would just about manage with company is often one step too far alone. Nobody can steady you on an awkward section, and nobody shares the decision to turn back. So plan solo hikes deliberately a notch easier than you could do.

Switzerland’s accident prevention bureau advises calculating time, distance and above all elevation gain realistically and generously. For demanding or remote tours, it recommends not going alone at all (BFU, sicher-bergwandern.ch, in German, as of October 2026).

Read the trail markings

In Switzerland, the colour of the signpost tells you what to expect (Swiss Hiking Trail Federation, trail categories, in German, as of October 2026):

Marking	Category	What it means
Yellow	Hiking trail	Ordinary attention and care are enough.
White-red-white	Mountain trail	Steep, narrow and exposed in places. You need to be sure-footed, free from vertigo and in good physical shape.
White-blue-white	Alpine trail	May cross snowfields, glaciers, scree and short climbing sections, partly without a path. Very good fitness and knowledge of alpine hazards needed; depending on the route also rope, ice axe and crampons.

For solo hikes, that means yellow and white-red-white trails are well suited to planning on your own. White-blue-white routes are only for people with a lot of alpine experience when alone, and even then company is the more sensible choice.

Plan exits and alternatives

Before you set off, mark at least one shortcut or bail-out point: a cable car, a hut, a descent into the next valley. Note the last public transport connections and the time of sunset. If you know where you can turn back, you are more likely to turn back in time.

Maps offline, not just online

On remote paths there is often no signal. Download the map to your phone for offline use, and on longer hikes take a printed map or a printout of the route. Paper needs no battery.

2. Weather: check before, watch during

In the mountains, weather decides more than fitness. Check the forecast the evening before and in the morning, ideally with a source that covers mountain locations.

The MeteoSwiss app shows forecasts and measurements, and you can subscribe to the federal natural hazard warnings for your locations as push notifications (MeteoSwiss blog on warning notifications, in German, as of October 2026).

When thunderstorms are possible, the BFU advises starting early, knowing your alternatives and postponing if storms are likely, not only once they are certain. Rain from the previous day also counts, because paths can stay wet and slippery for days (BFU, as of October 2026).

3. Tell someone: route and latest return time

This is the point that matters most when hiking alone, and the one many people treat too casually. The BFU recommends telling people you know about your route and destination, and getting back in touch after you return (BFU, as of October 2026).

What belongs in the message:

• Start and finish, with place names or the car park.
• The planned route and any variants. A link to the route or a screenshot of the map is enough.
• Your expected return and a latest return time. The second is the important one: from when should the person act?
• What to do then. Call you first. If that fails, alert Rega (1414) or the police (117) and pass on the route and starting point.

The weak spot in this plan isn’t the message, it’s the remembering. The person at home has to think at 8 pm that you should have been in touch. If you don’t want to rely on that, you can hand this part to a check-in app. More on that below.

4. Battery and kit

Your phone is your emergency phone

A flat phone is more than annoying when you are alone in the mountains. A few habits help:

• Start fully charged and carry a charged power bank with a cable.
• Use battery saver, and flight mode in areas without signal. Constant network searching drains power.
• Keep the phone warm. Cold empties batteries faster; an inside pocket helps.
• Use navigation sparingly. Open the offline map briefly, then close it.

The basics

Good boots, rain and cold-weather layers, enough to eat and drink, a small first-aid kit, a head torch and a foil blanket. On alpine trails, add whatever the route demands. Winter hiking or avalanche terrain needs training and avalanche equipment. That is a discipline of its own and beyond this checklist.

5. Emergency numbers and the Rega app

Save these numbers before you go (Graubünden emergency call centre, emergency numbers, in German, as of October 2026):

Number	For
1414	Rega, Swiss air rescue
144	Ambulance, medical emergency
112	European emergency number
117	Police

From abroad you can reach Rega on +41 333 333 333. For emergencies outside Switzerland, Rega recommends the local services or 112 (Rega, Rega app, as of October 2026).

The free Rega app is worth having on every solo hike. One tap alerts Rega, opens a phone connection and automatically sends your location to the operations centre. You can also share your location with Rega or with contacts. Important: the app needs at least minimal network coverage. With no network at all, it cannot raise the alarm either (Rega, Rega app, as of October 2026). Use the test alarm beforehand to check that everything works.

6. If you are back later than planned

You are on the trail and running late

Get in touch as soon as you have signal, even if you are fine. A quick “Taking longer, all good” stops someone at home from alerting rescue unnecessarily. If you notice time is getting tight, take the bail-out rather than carrying on in the dark.

You are injured or stuck

Call 1414 or 112, or raise the alarm through the Rega app. If possible stay where you are, put on warm layers and save battery. If you have no signal where you are, moving a short distance may help, as long as you can do so without risk.

The person at home hears nothing

This is where the latest return time pays off. Once it has passed, they try to reach you first. If that fails, they alert Rega or the police and give the starting point, route and time of your last message. The more precise this information, the more targeted the search.

Where a check-in app helps, and where it doesn’t

A check-in app such as Ondira takes over the remembering. Before the hike, choose an interval and check the resulting deadline: it should allow for your expected return plus a buffer. If you miss it, the app reminds you first. Only if that goes unanswered does your trusted contact get an email. There is no live tracking; the app only sends your location if you switch that on, and only at the moment you check in. The step-by-step flow is on How it works.

The limits matter just as much. The app needs a brief internet connection to check in, so you check in after the hike. And it does not alert Rega or any rescue service; it only emails your contacts. For the acute emergency, the Rega app is the right tool. If you would rather share your location continuously, our location sharing comparison explains the differences.

• Checked in after you’re back.

Frequently asked questions

Is it dangerous to hike alone?

Hiking alone isn’t dangerous in itself, but a mishap has bigger consequences because nobody can fetch help straight away. Choosing a suitable route, checking the weather and telling someone your route and latest return time reduce that risk considerably.

What does white-blue-white mean on Swiss trails?

White-blue-white marks an alpine trail in Switzerland. It may cross snowfields, glaciers, scree and short climbing sections, and requires very good fitness and knowledge of alpine hazards.

Which number do I call in a mountain emergency in Switzerland?

1414 for Rega or 112. For a medical emergency in the valley, 144. From abroad, Rega can be reached on +41 333 333 333.

Does the Rega app work without signal?

No. The Rega app needs at least minimal network coverage. With no network at all, it cannot raise the alarm.

Who should I tell when I go hiking alone?

Someone who is reachable and knows what to do if you haven’t been in touch by your latest return time. They should know the starting point and route. If you also live alone, it’s worth sorting out the everyday side at the same time.
