Travel itineraries, calculated, not guessed.

From a weekend to a four-week trip — the route, the stages, the activities and the hikes — by destination and month. You choose the balance of culture and nature, a relaxed or packed pace, and how far you want to walk; the engine calculates the rest, and warns you about anything that will not hold.

The problem

We counted the nights of long trips sold by different operators on four continents. Everywhere, the same pattern:

• a different hotel every day and a half;
• more culture than we had asked for;
• no breather in the middle of the trip;
• and, back home, two or three days nobody remembers.

It is not one operator's fault: it is how itineraries are composed. Places get stacked, and every stage is a line on the quotation. Nobody calculates the rhythm.

What we do instead

We calculate the itinerary instead of composing it. In three steps.

1. You choose.

• Where and when: the area, the departure date, and your duration — fixed, or flexible if your programme calls for another.
• Who with: as a couple, with friends, as a family.
• The balance: the share of culture you want; the rest is nature.
• The pace: a relaxed, balanced or packed daily load, to make the most of it.
• Walking: how far you want to go, from a gentle stroll to a full day's hike.
• Your activities: hiking, kayak or canoe, easy cycling, via ferrata, wildlife watching, village strolls, city visits.
• Your heat ceiling and your type of lodging.

2. The engine calculates. The real climate of the month in your area, during the hours you will be outdoors. How many days your programme needs — and, if your duration is flexible, what a different length would change. How to cut it into stages, how many nights each, where the days with no plan fall. Distances on the real road. Then it checks that the whole thing holds together.

3. You get variants, not a programme. Two or three itineraries that do not resemble each other, each with its strengths and its choices explained — day by day, hikes included if you want them. And if something does not hold — an overloaded day, an impossible link, a ferry, a mountain road or a permit to check for your dates — you are warned.

What it changes

The trip you chose. The share of culture and nature is counted in nights, and it matches your setting.

Your pace, not the catalogue's. Relaxed or packed, every day is sized to hold — no forced idle time, no rush.

The effort that suits you. Walks stay within the limit you set.

Stages that make sense. You change lodging when the content justifies it, not to fill a programme.

A breather at the right time. Days with no plan fall in the middle of the trip, where they help — never at the end.

The right month, the right hours. Days are built under your heat ceiling, with the month's real rain.

No surprises on the spot. What you need to check yourself is listed, with the source to consult.

And compared with an operator, or ChatGPT?

An operator takes everything off your hands, control included: the rhythm follows the catalogue. An AI assistant answers what you ask it — you still have to know what to ask. We ask the questions, we calculate, and we explain every choice.

The full argument

Why trust us

It started with field observations on our own trips. Behind them is research into how the industry builds itineraries, an engine modelled and tested with AI on more than forty simulated circuits — over 1,000 stages and 900 legs measured — and a comparison with itineraries published by agencies and travel bloggers. The studies that came out of it:

• Eleven hotels in twenty nights — why itineraries move you so often.
• It isn't the north you're looking for — escaping heat is a matter of ceiling, not latitude.
• Where to put the day with no plan — in the middle, never at the end.
• The Baltics repeat themselves — when repetition is a problem, and when it isn't.

Every figure has a source, and our errors are published. All studies · The method

Also in the studies: How many hotels for a road trip · Is your itinerary too packed? Four counts · What is your heat ceiling? · Rain days or rain hours · Six campgrounds, six nights
