An AI planner for hut-to-hut treks in the Alps

In short

TrailNights is a free AI trip planner. Tell it your budget, how many nights and the kind of trek you want, and in a minute or two you get a day-by-day itinerary where every mountain night is a real hut or refuge from a table of 5,826 shelters across 48 areas, with altitude, beds, warden season and how to book. You can plan 3 trips a month, with an account or without.

Every flight, stay and activity comes back with a live booking link.

How it works

You start from the brief, not the destination. Say in one sentence what you want, for example "six days hut to hut in the Dolomites in July, under 1,200 euros each", and set the budget, the nights and who is going. If you have no destination yet, give it a budget and a mood and it will suggest one.

The route is built from huts retrieved from the table, not from the model's memory. When the planner proposes a night in the mountains it chooses among the shelters that exist near the route, and a stay it could not match to a real record is marked as unverified on the page instead of looking certain.

Every item comes with the way to book it: for huts, the Alpine Club booking system or the hut's own phone number; for flights, a current fare; for valley hotels, a direct link. A day that does not suit you can be rebuilt, and the whole trip can be saved and shared as a link.

What it draws on

5,826 huts and shelters across 48 areas of the Alps, the Pyrenees and Corsica, 2,459 of them staffed in season. 1,537 publish a phone number and 158 carry a direct booking link. Alongside them, 10 classic routes, among them the Tour du Mont Blanc, Alta Via 1 and 2, the GR20 and the Haute Route, with the huts along every stage.

The records come from two open databases that hikers maintain, refuges.info and OpenStreetMap. Where something was not published, a warden season or a bed count, the page says so instead of guessing.

Who it is for

This section is our advice and judgement, not a sourced figure. Prices, dates and counts elsewhere on the page come with a source below.

People planning a first hut trek who want to see what a week in the mountains looks like on their budget. People who have picked a route and want every hut along it in one place. And people who have dates and a figure but no destination yet.

It plans trips that are not in the mountains too: a city, a coast, a weekend away. The real huts are what sets it apart, not a requirement.

What it does not do

This section is our advice and judgement, not a sourced figure. Prices, dates and counts elsewhere on the page come with a source below.

It does not check live availability and it does not book for you. You reserve the bed with the hut or its system, and the guide to hut availability explains why it works that way.

Nor does it replace checking the weather and the state of the path before you set out. An itinerary written by an AI is a good starting point, not confirmation that a path is open or a pass is safe that week.

Questions people ask

How much does the planner cost?
Planning is free. You can plan 3 trips a month, with an account or without. Huts, flights and hotels are paid to the providers directly. Some booking links earn us a commission, and it never changes your price.
Where do the huts in the itinerary come from?
From a table of 5,826 shelters built from refuges.info and OpenStreetMap. Each keeps its altitude, beds, warden season, winter room, booking policy and phone number where they were published.
Can I book a hut through the site?
No. Each hut shows how to book it, a link into the Alpine Club system where there is one and its phone number otherwise, and you reserve with them. We do not show live availability.
Which regions have real huts in the itinerary?
The Alps of France, Italy, Switzerland, Austria, Germany and Slovenia, the Pyrenees and Corsica: 48 areas in all. The planner runs for any destination, but nights in huts from the table exist only in those areas.
Does it work in Hebrew?
Yes. The itinerary is written in Hebrew, place names appear in Hebrew where a standard Hebrew name exists, and the whole interface runs right to left. The same trip opens in English too.
How long does an itinerary take?
Usually a minute to a minute and a half. The first day appears after about 20 seconds and the rest is written while you read.
