Find hut-to-hut routes you can actually book
668 hut calendars checked once a day, last checked 4 September 2026. We read the huts' own booking systems, then build a walking route that joins the huts that have beds.
Free this season, on the web and on Android and iOS.

Booking a hut-to-hut trek means checking a different reservation system for every hut, on every night, and starting again when one of them is full. HutScanner checks them for you and links the huts by real walking routes, so you can see which sequences work before you start booking.
Why you can trust the numbers
Anyone can put a bold claim on a website. These are the four things that make ours checkable.
Read from the huts' own booking systems
Not from a list we typed. The alpine club portal, the Italian CAI portal, the Tour du Mont Blanc platform and a number of individual hut booking pages. Every hut page shows when that hut was last checked and links to the calendar the figure came from, so any night can be checked by hand in a few seconds.
A daily record, in public
Our Tour du Mont Blanc page is rebuilt every morning from that morning's calendars. Of the 37 mornings recorded since 13 June 2026, it found a complete loop on 37. The record is public, so a morning it could not would be visible too. See today's. Behind it, 46 days of availability across the Alps are banked.
Two named bots, and a stop switch
HutScannerAvailabilityBot does the once-a-day pass. HutScannerUserBot fetches on demand, only for the huts on someone's own route. Both name themselves and carry a contact address, and any hut warden can ask for either one to stop. How that works.
Planning, not booking
HutScanner never holds a bed and never takes a payment. It finds the nights that work and sends you to the hut's own reservation page. That is also why we have no reason to overstate what is open.
Start here
The pages worth reading before the map: the Tour du Mont Blanc stage by stage, whether it is still bookable this season, and what our record of the huts' own calendars says about where there is space.
- Tour du Mont Blanc: every stage, hut and walking time
Walking times from our own routing, the huts on each stage, and the shorter versions.
- Can you still do the Tour du Mont Blanc right now?
Rebuilt every morning from the huts' own calendars: the earliest departure with a bed every night.
- How to plan a hut-to-hut Tour du Mont Blanc
Booking order, the platforms involved, and what to do when one stage is full.
- The Alps are not full, they are concentrated
A settled month of the huts' own calendars, hut by hut, and what the alpine clubs themselves say about it.
- When do alpine huts fill up?
Measured from daily snapshots rather than folklore: which nights and which massifs fill first.
- How alpine hut booking actually works
Seven booking platforms, club portals, email and phone, and which huts use which.
- Walker's Haute Route huts
Chamonix to Zermatt: which nights are huts, which are valley towns, and how the two booking systems split.
- Bernese Oberland huts
SAC huts on one booking platform, with the calendar open to anyone.
- Vanoise huts
Park refuges and CAF refuges on two portals, and the traverses between them.
- For hut wardens and booking platforms
How the daily check works, which bots do it, and how to correct or stop it.
Plan it on the web, walk it with your phone
The things that matter are on both: the whole alpine hut network across 69 regions, availability synced daily, chains of huts that have beds on consecutive nights, and routes computed over real trail data with grades - so a "shortcut" across a glacier is labelled as one. What follows is what each one is better at.
In your browser
-
Nothing to install
Open it and start planning. No app store, no account, no sign-up - and a big screen for the part that involves a lot of dates.
-
The route in detail
Elevation profiles for each day and for the whole trip end to end, every alternative line for a leg, and the terrain grade behind each one.
-
Share a plan by link
Send the itinerary to whoever you are walking with. They do not need the app, or an account, to open it.
On your phone
-
Works with no signal
The maps, the hut network and your routes are bundled onto the device. The valleys worth walking are the ones without a bar of reception, and that is where a plan has to survive.
-
The hut's details in the valley
Phone numbers, booking pages and opening seasons come with the pack, so you can still ring ahead from the trail when a night falls through.
-
The same trip, either place
Build it on a laptop at home and it is on the phone in your pocket. Availability catches itself up the next time you have a connection.

Know when the huts open before they fill
The stages everyone walks are booked out months ahead, and every hut opens its season on its own schedule. At most one email a month, from the same daily sync the planner runs on.
-
The availability picture
Which regions still have beds on the popular nights, which are filling, and where the quiet ground is.
-
New regions before anywhere else
When a region pack goes live it is in that month's letter first.
-
No account, and no other mail
An address is all we take. We send a link to confirm, and every issue has a one-click way out.

Start from a classic route
Open one of these and the map draws the line, the huts along it, and where there is space right now.
- Tour du Mont Blanc The classic circuit of the Mont Blanc massif, through France, Italy and Switzerland. Every stage ends at a hut or gite you can book. Open on the map →
- Walker's Haute Route Chamonix to Zermatt on foot, across eleven passes. Most nights are in valley towns rather than huts, so we show the line and let you build the chain. Open on the map →
- Tour des Glaciers de la Vanoise The circuit of the Vanoise glaciers from Pralognan, France's first national park. Every stage ends at a bookable refuge. Open on the map →

Questions
- What is HutScanner?
A planner for hut-to-hut treks across the Alps. It reads hut availability from the huts' own booking systems and finds chains of huts with beds on consecutive nights, connected by walking routes you can do in a day. It is built by one person; the details are on the about page.
- What can HutScanner do?
It maps 3562 huts across 69 regions with walking routes between them, and shows availability for 668 of them. It will find a route for you from a start hut, a date window and a number of nights. It will find the best dates for a route you already have, including hut swaps and rest days. It re-checks a route's huts on demand when you are about to book. It can watch a hut or a whole route and email you when beds return. Any route exports as GPX or as a booking plan, and the maps and hut details work offline on the phone.
- What can't it do?
It cannot book or hold a bed for you. It cannot read a calendar for a hut that does not publish one, and those huts are shown in blue or gold rather than pretending to a status. And it cannot promise you a bed: availability is checked once a day and a hut can fill at any moment, so treat it as a strong guide and confirm with the hut.
- Is there a tool that automatically finds a bookable hut-to-hut route?
Yes, that is what the route finder does. Give it a start hut, the dates you could leave and how many nights you want, and it searches combinations of huts that have beds on consecutive nights and are a day's walk apart. Open the planner, or see a worked example rebuilt every morning on the Tour du Mont Blanc.
- Can HutScanner find a route if I do not know where I want to go?
Yes, and that is what the route finder is for. Give it a date window and how many nights you want and it searches for chains of huts that have beds on consecutive nights and are a day's walk apart, without you naming the huts. If a chain does not quite work it will shift the dates or swap in a neighbouring hut to make one that does. If you plan trips through ChatGPT or Claude, they can run this same search for you and hand back a link that opens the result in the planner; how that works is described in using HutScanner with AI assistants.
- How do you know which huts have space?
We read the huts' own booking systems, the alpine club portal, the Italian CAI system, the French club systems and several individual hut engines, and refresh them daily. It is a best-effort guide, not a reservation: you still book with the hut, and you should always confirm with them directly.
- Does it book the huts for me?
No. It finds the nights that work and links you straight to each hut's own reservation page. Booking, payment and cancellation all happen with the hut.
- What does it cost?
It is free this season to use, on the web and on Android and iOS.
- Does it work without a phone signal?
The mobile app bundles the maps and the hut network, so your route and the map still work in a valley with no coverage. Live availability needs a connection, so check it before you set off.
- When should I book an alpine hut?
For popular routes in July and August, weeks to months ahead. Many huts open their season's bookings in the spring and the well-known stages fill first. Quieter regions and shoulder-season dates are often bookable much later.
- Can I be told when a hut that is full has space again?
Yes. You can set a watch on the nights you want and get an email when space opens up. A watch covers the whole route rather than one hut, so it only tells you when a set of nights works together, not when any single bed appears. It needs no account. Watches work on huts whose booking system publishes a live calendar, which is how we can see a night change from full to free.
- Can I export a route as a GPX file?
Yes. Any route exports as GPX, with a waypoint for each hut and the walking line for each day, so it opens in Garmin, Komoot, OsmAnd, Gaia and most other navigation apps. Always check the line against a map before you walk it.
- Can it use cable cars, buses and trains?
Yes, if you turn them on. Lifts and mountain railways are part of the route network, so a day can start or end with a ride rather than a walk, and the planner leaves the ride out when the hut is an easy enough walk anyway. Ride times for the hand-checked lines come from their timetables; elsewhere they are estimates, so check the operator before you rely on a connection.
- Which areas are covered?
The Alps, across France, Italy, Switzerland, Austria, Germany and Slovenia, with the Pyrenees and Scandinavia in preview.
- Can an AI assistant use HutScanner to find me a route?
Yes. HutScanner publishes a structured API, so an assistant you already use can search with your trip details and get back real bookable routes, each with a link that opens it in the planner. The endpoint and its limits are documented in using HutScanner with AI assistants.
- Does HutScanner cover the whole Alps or just the Tour du Mont Blanc?
The whole Alps. The Tour du Mont Blanc is our busiest region, not our only one: 3562 huts are mapped across 69 regions in six countries.
