Quick personal advice
These terms apply to the optional “Wetter Flex” service that you can add to a hut-night booking arranged through Bookatrekking. Bookatrekking acts as an intermediary between you and the mountain huts; it is not a tour operator and not an insurer. Wetter Flex supplements Bookatrekking’s standard cancellation terms. In the event of a conflict on the subject of weather conditions or wildfire closures, these terms prevail.

1. Definitions

In these terms, the following terms have the meanings set out below:

  • Bookatrekking: the intermediary for booking hut nights. Bookatrekking does not itself provide transport or package travel and is not an insurer.
  • Accommodation amount: the total amount you pay through Bookatrekking for the mediated hut nights, including any half board offered and booked through the hut. Self-booked flights, your own transport and other third-party costs are not included.
  • Wetter Flex fee: the one-off service fee for adding Wetter Flex to your booking.
  • Trek / trip: the consecutive multi-day route fixed at the time of booking, including the dates and hut nights.
  • Trek day: a calendar day on which you actually walk a stage of the booked route.
  • Trek region: the geographic area in which the booked route lies, as recorded in the booking confirmation and traceable to the warning areas (warning zone) of the national weather service.
  • Qualifying weather warning: an official orange or red weather warning that meets the conditions in article 4.
  • Wildfire closure: an official closure or evacuation of (part of) the booked route or a booked hut because of a wildfire or the threat of one, ordered by a competent authority (for example the prefecture, region, municipality or national park). See article 4.
  • Official weather warning (allerta): the official warning bulletin with a colour code (yellow/orange/red) from the competent weather service for a specific warning zone. This is the legally binding signal — not an ordinary weather forecast.
  • Warning zone: the area delimited by the competent weather service for which the colour code applies, and which the trek region falls within.
  • Validity horizon: the period for which an official warning is issued and remains valid (see article 4.1).
  • National weather service: the official weather service of the country in which the trek region lies (e.g. GeoSphere Austria, MeteoSwiss, DWD). For Italy this is the regional Centro Funzionale Decentrato (CFD) and ARPA. If the route runs through several countries or regions, the service of the area in which the relevant stage lies applies.

2. What is Wetter Flex?

Wetter Flex is an optional flexibility service. With Wetter Flex you extend the cancellation and amendment options of the hut nights booked through Bookatrekking, in case your trek is affected by a qualifying weather warning or a wildfire closure. In that case Bookatrekking, as intermediary, arranges the cancellation or rebooking with the huts and refunds the accommodation amount in accordance with the basis set out in article 6.

Wetter Flex is expressly not insurance. You are not buying cover against loss and you do not receive a claim payout. Wetter Flex is an extension of the terms of your own booking: it concerns the refund and rebooking of your own reservation, not compensation for an external risk.

What Wetter Flex refunds. Wetter Flex refunds only the hut nights booked through Bookatrekking that you are unable to use because of the weather or a wildfire closure. Your own costs for replacement accommodation or transport are not reimbursed and remain for your own account (where applicable, via your travel insurance).

3. Adding Wetter Flex and costs

  • Wetter Flex can be added at the time of booking and up to 14 days before your first trek day.
  • The amount of the Wetter Flex fee is shown when booking and is payable once when Wetter Flex is added. If you pay a deposit, you pay the Wetter Flex fee with the remaining payment.
  • The Wetter Flex fee is the service fee for the flexibility and is non-refundable, with two exceptions: you get the Wetter Flex fee back if you cancel your booking 8 weeks (56 days) or more before departure, or if your whole booking is cancelled by the hut or by Bookatrekking (see article 10). If you cancel later, or if you make use of Wetter Flex, the fee is not refunded.
  • One Wetter Flex service applies per booking, regardless of the number of travellers on the booking.

4. When can you use Wetter Flex

You can make use of Wetter Flex once there is a qualifying weather warning. This is the case when all of the conditions below are met at the same time:

  • there is an official orange or red weather warning (for Germany and Switzerland: the equivalent level, see article 5);
  • the warning concerns rain, thunderstorms, wind, snow and/or heat;
  • the warning has been issued by the national weather service (or, for Italy, the regional CFD/ARPA) of the relevant country;
  • the warning applies to the warning zone in which the trek region of your booked route lies;
  • the warning is in force on at least one of your trek days.

Assessment per trip. Whether there is a qualifying weather warning is assessed at trip level: one valid warning on one trek day is enough to activate Wetter Flex. This keeps the assessment objective and simple. The amount of the refund then follows from the tiered model in article 6.

Wildfire. Wetter Flex also applies if there is a wildfire closure (see article 1) for the booked route or a booked hut on at least one of your trek days. A wildfire danger level or warning, smoke or poor air quality without an official closure or evacuation does not count. The refund follows the tiered model in article 6, in the same way as for a qualifying weather warning.

4.1 Timing and horizon of the warning

Only the official colour code counts as a trigger — not a weather forecast, however unfavourable. It is important to understand how the timing works:

  • The competent weather service issues the official warning bulletin (the allerta / bollettino di criticità) as a rule daily, by 13:00 at the latest, with a validity horizon of approximately 36 hours.
  • An official orange or red code is therefore usually only known about 24–36 hours in advance. A poor weather forecast earlier in the week is not yet a qualifying weather warning; the code for a given day only appears in the bulletin of the preceding day(s).
  • The reference point for the assessment is the official code that applies to your trek day(s). A forecast or outlook that is not subsequently converted into an official code does not activate Wetter Flex.

5. Objective criteria — what counts and what does not

Counts (qualifying weather warning or wildfire closure) Does not count
  • Official orange or red code
  • For rain, thunderstorms, wind, snow or heat
  • From the competent weather service
  • Valid in the warning zone of the trek region
  • On ≥1 trek day
  • Or: an official closure or evacuation due to wildfire, ordered by a competent authority, for the route or a booked hut on ≥1 trek day
  • Yellow warnings
  • Wildfire danger levels, smoke or poor air quality without an official closure or evacuation
  • Disappointing or unfavourable forecasts (incl. multi-day previsioni or vigilanza outlooks) without an official code
  • Subjective judgements or "unpleasant weather"
  • Warnings outside the trek region or outside your trek days

Which level counts per country. Weather services do not all use the same scale. Where these terms and conditions mention an orange or red warning, the following applies:

Country Counts
France, Spain, Austria, Italy and other countries with a yellow, orange and red scale Orange or red
Switzerland Danger level 3, 4 or 5
Germany Level 3 (“Unwetterwarnung”, red) or level 4 (“Warnung vor extremem Unwetter”, dark red). For heat: “extreme Wärmebelastung”. Level 2 (“markantes Wetter”, orange) does not count.

This clear delineation keeps the assessment objective and transparent and prevents later disputes.

6. The refund — tiered model

The form of the refund depends on when the qualifying weather warning or wildfire closure affects your trip. Where this article refers to a warning, this also means a wildfire closure. We distinguish three situations.

6.1 Tier 1 — Weather warning before departure (trip not yet started)

The warning applies before your first trek day and concerns at least one planned trek day. You have not yet used any nights. You have the choice between:

  • rebooking free of charge to another available date;
  • cancelling the mediated hut nights with a refund of 100% of the accommodation amount. The Wetter Flex fee is not refunded.

6.2 Tier 2 — You abandon the trek during the trip

The warning occurs while you are en route and you decide to abandon the trek. Bookatrekking refunds all hut nights booked through Bookatrekking that you no longer use from that point onward. Nights already used are not refunded, as they have already been provided.

Example: you have booked 7 hut nights and abandon the trek after the 4th night due to an orange warning. The 3 unused hut nights are refunded.

6.3 Tier 3 — You continue, but skip one or more days

The warning affects one or a few days, but you largely complete the trek. For example, you skip a day due to bad weather and walk on afterwards. Bookatrekking refunds the hut night(s) booked through Bookatrekking that you skipped and did not use as a result.

You arrange and pay for any replacement accommodation in the valley and any transport yourself; these costs are not covered by Wetter Flex.

6.4 Overview

Situation When Refund
Tier 1 Warning before departure; nothing used yet Free rebooking or 100% of the accommodation amount refunded. Wetter Flex fee not included.
Tier 2 You abandon the trek during the trip Refund of all unused hut nights from the moment you abandon
Tier 3 You continue but skip 1+ days Refund of the skipped, unused hut night(s); replacement accommodation and transport at your own expense

7. Making use of Wetter Flex

To use Wetter Flex, you submit a request to Bookatrekking. You provide:

  • your booking number;
  • proof of the official orange/red warning from the national weather service, with date and area, or, in the case of a wildfire, the official closure or evacuation notice of the competent authority (for example a screenshot or link). This proof is mandatory;
  • for Tier 2 and Tier 3: a statement of which hut nights you did not use.

A request must be submitted within 30 days of your last planned trek day. Wetter Flex can be used once per booking. A free rebooking under Tier 1 does not count as use: Wetter Flex remains valid for the new date.

8. Handling and refund

  • Bookatrekking assesses your request solely against the objective criteria in articles 4 and 5 and the official weather data or closure notice. Because those criteria are objective, there is no assessment at our own discretion.
  • Approved refunds are paid within 30 days of approval to the account used to pay for the booking.
  • In the case of rebooking (Tier 1) no payment is made; the value of the booking and the Wetter Flex service move to the new date.

9. Exclusions

There is no right to a refund under Wetter Flex in the following cases:

  • no official orange or red weather warning has been issued for the warning zone of the trek region on a trek day, and there is no wildfire closure (see articles 4 and 5);
  • the warning is a yellow warning;
  • there is only a wildfire danger level or warning, smoke or poor air quality, without an official closure or evacuation;
  • there is only an unfavourable weather forecast or outlook that has not (yet) been converted into an official code (see article 4.1);
  • costs of alternative accommodation, transport, self-booked flights or other items not included in the accommodation amount; these remain at your own expense;
  • cancellation or interruption for reasons other than the qualifying weather warning or wildfire closure (for example illness or personal circumstances);
  • costs already covered by insurance (see article 10).

10. Interaction with other terms

  • Wetter Flex does not affect Bookatrekking’s standard cancellation terms and applies in addition to them. The existing option to cancel free of charge up to 8 weeks (56 days) before departure remains in place; in that case you also get the Wetter Flex fee back. Wetter Flex is mainly relevant in the period after that and during the trip.
  • If a hut or Bookatrekking cancels or changes your booking for a reason other than a qualifying weather warning or a wildfire closure (for example because there is no availability), the standard terms of Bookatrekking and the hut concerned apply, not Wetter Flex. If your whole booking is cancelled in this way, you also get the Wetter Flex fee back. If a hut is closed or cannot be reached because of a qualifying weather warning or a wildfire closure, Wetter Flex does apply (articles 4 to 6).
  • Wetter Flex does not refund costs already covered by insurance (such as travel or cancellation insurance). Double compensation of the same costs is excluded.

11. Final provisions

  • Bookatrekking may amend these terms for future bookings. The version that applied at the time of booking applies to your booking.
  • These terms are governed by Dutch law.
  • Questions about Wetter Flex or a request can be addressed to Bookatrekking’s customer service.

Carefree Plus

Carefree Plus is an optional service you can choose when booking: Wetter Flex, plus free cancellation up to 31 days before departure and one free rebooking. Carefree Plus is not insurance. Anything not covered here is governed by the general terms and conditions and the Wetter Flex terms above. Where those terms differ from what is stated here, these terms take precedence.

What it costs

The surcharge is 7% of the trek price (after any discount code), on top of the Wetter Flex fee. You can only choose Carefree Plus when booking, for treks where it is offered and when your departure is more than 30 days away. If you pay a deposit, you pay the surcharge with the remaining payment. Carefree Plus applies per booking, for all travellers.

Cancellation

If you cancel 8 weeks (56 days) or more before departure, you get everything back: the trek price, the Wetter Flex fee and the surcharge. If you cancel later, but no later than 31 days before departure, you get the full trek price back, but not the Wetter Flex fee and the surcharge.

CancellationTrek price backWetter Flex fee and surcharge back
56 days or more before departure100%Yes
55 to 31 days100%No
30 to 29 days50%No
28 to 15 days25%No
14 days or less, or no-show0%No

The percentages apply to the trek price. We count full calendar days before the departure date.

Rebooking

You can rebook once for free to another available start date if you request this more than 30 days before the original departure date. After a rebooking, the standard cancellation terms apply to the new date; Wetter Flex remains. You pay no rebooking fee; any price difference with the new date will be settled. Once you have rebooked, you no longer get the surcharge back, also not if you later cancel 8 weeks (56 days) or more before the new departure date. A change made by a hut or by us does not count as your rebooking.

Cancelling part of your trek

If you cancel part of your trek (for example one day or half of the route) between 55 and 31 days before departure, this counts as your one free rebooking. You get back the trek price of the part you cancel. After that, the standard cancellation terms apply to the rest of your booking, and you can no longer rebook or cancel for free. You do not get the Wetter Flex fee or the surcharge back, also not in part. If you have already rebooked, the standard cancellation terms apply to a partial cancellation.

Severe weather and wildfire

In the event of an official code orange or red on your route, or an official closure due to wildfire, the Wetter Flex terms apply: before departure you get 100% of the amount for your hut overnight stays back or rebook for free; on the trail you get back the money for the overnight stays you no longer use.

How to arrange it

You cancel in the customer portal or via customer service, and rebook via customer service. Approved refunds are paid within 30 days of approval to the account you paid with. The terms in force at the time of booking apply to your booking; Dutch law applies.
