Mountain vacation rental guests face unique risks: altitude sickness, sudden weather changes, trail difficulty misjudgment and limited phone signal. A welcome book with a clear mountain safety section — including trail difficulty ratings and emergency procedures — is essential for any property above 800 meters.
Altitude Sickness: Symptoms and What to Tell Your Guests
Acute mountain sickness typically appears above 2,500 meters, though sensitive guests can feel the first symptoms from around 2,000 meters — well within range for many alpine chalets. Warn guests staying at higher elevations about headache, nausea, dizziness and poor sleep on the first night or two, and tell them these usually fade as the body acclimatizes.
The one instruction that actually matters is simple: if symptoms worsen rather than improve, guests should stop ascending, rest, and descend if things don't improve within a day. Confusion, severe breathlessness at rest, or unsteady walking are warning signs that need a doctor immediately, not a "sleep it off" approach. Guests arriving straight from sea level by car or cable car are most at risk, since they skip the gradual altitude gain that hikers get naturally.
"If you get a headache, feel unusually tired or slightly nauseous during your first day here, that's common at this altitude. Rest, drink water, and avoid alcohol. If it gets worse instead of better, please contact us or call 112."
Trail Difficulty Ratings Explained (European Systems)
Trail difficulty is not standardized across Europe, and a guest who hiked comfortably in one country can be caught out by a differently graded trail elsewhere. The three systems your guests are most likely to encounter are the Swiss SAC/CAS hiking scale, French GR/PR waymarking, and the Italian CAI scale — and none of them map neatly onto each other.
| System | Where used | Grades (easy → hard) | What it means for guests |
|---|---|---|---|
| SAC/CAS hiking scale | Switzerland, parts of Austria | T1 Hiking → T2 Mountain hiking → T3 Demanding mountain hiking → T4 Alpine hiking → T5 Demanding alpine hiking → T6 Extremely difficult | T1–T2 are fine in trail shoes; T3 and above need hiking boots, sure-footedness and a head for exposure; T4+ can involve scrambling or via ferrata-style terrain |
| GR / PR waymarking | France | PR (yellow marks, local day walks) / GR (red-and-white marks, long-distance) / GRP (red-and-yellow, regional loops) | The marking indicates the type and length of route, not a strict difficulty grade — a long GR stage can be far tougher than a short one |
| CAI scale | Italy | T (Tourist) → E (Hiking) → EE (Expert hikers) → EEA (Expert hikers with equipment) | E is the everyday range for capable walkers; EE and EEA trails are not suitable for casual guests, and EEA usually means via ferrata gear is required |
Tell guests plainly which grade the trails near your property fall into, and don't assume the color of a waymark alone communicates difficulty.
Phone Signal and Emergency Calls in Remote Mountain Areas
112 is the emergency number across the EU and also works in Switzerland, but coverage in valleys and on north-facing slopes can drop to nothing, sometimes for long stretches of a trail. Tell guests exactly where signal typically disappears near your property, and recommend they download offline maps before setting out rather than relying on a live connection.
A text message can sometimes get through where a call fails, since SMS needs far less signal strength — worth mentioning explicitly, since few guests know this. Suggest guests tell someone their planned route and expected return time before a longer hike, since this is often what turns a delay into a manageable situation rather than a search operation.
Avalanche Awareness for Winter Rental Guests
The European avalanche danger scale runs from 1 (low) to 5 (very high), and it's published daily by the national avalanche service for your region — guests should check it before any winter walk or ski tour that leaves marked, secured pistes. A rating of 3 ("considerable") already means avalanches can be triggered by a single skier or walker, which surprises many guests who assume danger only starts near the top of the scale.
Point guests to the specific website or app used locally, and make clear that marked ski pistes are avalanche-controlled while backcountry and off-piste routes are not, even if they start right next to a lift.
What to Include in a Mountain First Aid Kit
Beyond a standard first aid kit, mountain properties benefit from a few extra items: a foil emergency blanket, a whistle, blister plasters, and a printed card with the local mountain rescue number and your property's exact coordinates or what3words address. Cell signal gaps make a physical, printed card more reliable than a phone note in a genuine emergency.
Store the kit somewhere guests will actually find it — by the front door or with the hiking maps — rather than in a drawer no one opens, and mention its exact location in the welcome book itself.
FAQ
At what altitude does altitude sickness start?
Symptoms typically start above 2,500 meters, though some guests notice mild effects from around 2,000 meters. Below that, most people acclimatize without any issue.
Which trail difficulty system should I use in my welcome book?
Use whichever system is signposted on the trails near your property, and briefly explain what the grades mean rather than assuming guests already know the local convention.
Does 112 work everywhere in the mountains?
It's the standard emergency number across the EU and in Switzerland, but signal coverage in remote valleys can be patchy or absent — encourage guests to download offline maps and note dead zones in your welcome book.
Is it safe to hike off-piste in winter if the avalanche risk is only "moderate"?
Not automatically — even at moderate risk, avalanches can be triggered on steep terrain. Advise guests to check the daily bulletin and, ideally, stick to marked and secured routes unless they have relevant experience.
What's the single most important thing to include in a mountain safety section?
Clear guidance on when to turn back or call for help, in plain language — most guest incidents come from pushing on rather than from a single dramatic event.
