PATHFINDERS

Frequently asked questions

Where the routes come from, how accurate they are, how the Go arrow works, shelters, offline use, weather and aurora.

What is Pathfinders?

One place for every mapped route in Denmark — hiking, MTB, cycling, running and canoe — with the weather where the route starts, shelters nearby and an arrow that points you to the trailhead. Free, no ads.

Where do the routes come from?

From OpenStreetMap, the free world map maintained by thousands of volunteers. We fetch every route in Denmark at regular intervals. The featured routes on the front page are partly written by us, partly chosen automatically among national and regional routes.

How accurate are they?

As accurate as the map. Most major routes are drawn precisely; small local ones may have gaps or be out of date. Length is calculated from the map when OpenStreetMap doesn't state it. Always follow the waymarks on the ground rather than the screen.

A route is missing or wrong — what do I do?

Fix it in OpenStreetMap. Anyone can create an account at openstreetmap.org and edit; the change reaches Pathfinders at the next update. Every route page links straight to the route in OpenStreetMap.

How does the Go arrow work?

It uses your phone's GPS and compass to show direction and distance to a point — a trailhead, a shelter, or a pin you dropped yourself. The link can be shared so everyone gets the same arrow. Nothing is stored on a server; your position never leaves the phone.

The arrow points wrong or doesn't move

Enable the compass when asked and step outside — indoors and near cars or metal the compass drifts. Wave the phone in a figure-eight to calibrate. Open the site in Safari or Chrome, not inside Facebook's or Instagram's built-in browser, which blocks the sensors.

Does it work offline?

Yes. Add Pathfinders to your home screen and the pages you've opened, your saved routes and the route list work without a connection. Map tiles do need signal.

Where does the weather come from?

From Open-Meteo, which combines national weather services' models including DMI's. The forecast is for the route's start point. "Start by" assumes an easy pace — 4 km/h on foot, 12 km/h on an MTB — and a 30-minute margin before sunset.

What does the aurora forecast mean?

The Kp number is NOAA's forecast of geomagnetic activity. From Denmark the northern lights are usually visible at Kp 5 and above, and only with clear skies and a dark northern horizon. Look for a faint greenish glow low in the north.

Can I count on a shelter?

No. Shelters and tent sites come from OpenStreetMap and don't show whether a site is taken or needs booking. Always check udinaturen.dk, where the Danish Nature Agency shows rules and booking.

Can I get the route as a file?

Yes — "Download GPX" on the route page gives a GPX file for watches, bike computers and apps like Komoot and Garmin.

What does the site store about me?

Nothing on our side. There are no cookies, no analytics and no account. Your phone keeps your saved routes and your view preference in the browser's local storage, which you can clear at any time in the browser settings. Your position is used only in the browser, for the weather and the Go arrow, and is never sent to us. Weather, map and aurora data are fetched directly from Open-Meteo, CARTO, OpenStreetMap and NOAA, which therefore see your IP address as with any other request on the web.

Who is behind it, and what does it cost?

Pathfinders is a private project. It is free, ad-free and doesn't track you. Map: © OpenStreetMap contributors and CARTO. Weather: Open-Meteo. Photos: Wikimedia Commons, with photographer and licence shown by each image.
