Ridgeflow Get started

The world's great hikes.
On a real topo map.

Plan the Routeburn, the Tongariro Crossing or the trek to Everest Base Camp on contour topo and 3D satellite terrain. See every hut on the way, the climb in each day, the weather at each stop — then take it all with you, offline.

Try every feature for 7 days. A card starts the trial; nothing is charged until day 7, and you can cancel in the app before then. No ads, and we never sell your data.

Why this exists

Most maps stop where the road does.

General-purpose maps are built for driving. In the mountains the things that decide your day are not there: how steep the next kilometre is, whether there's a hut at the far end, what the weather does on the pass, whether the track is even open. Then you lose signal and the map goes blank.

Contours, not just lines

A trail drawn on a flat grey background hides the 1,200 m of climb in it. Terrain is the information.

The agency's own data

Park services publish grades, walking times, huts and closures. Ridgeflow carries them, so you don't find out at the trailhead.

Offline, or it doesn't count

Download a region before you go and the map, the 3D terrain and the trail data stay on your phone — 42 regions on six continents.


The map

A printed topo sheet, computed for anywhere on the planet.

Contour lines are usually a national mapping-agency product, which is why most apps have them for one country and nowhere else. Ridgeflow draws them in your browser from elevation data, so the map over Patagonia is the same map as over the Southern Alps.

Contour cartography, drawn live

Index and intermediate contours with height labels, glaciers, water, hillshade, peaks, passes and huts — drawn as a topo sheet, not a street map with trails on top.

  • Metres or feet, switched anywhere in the app
  • Peak heights from the publisher's own figures
  • Labels stay upright when you rotate or tilt

Contours drawn in the browser. In New Zealand they come from LINZ's 8 m bare-earth elevation.

Satellite and 3D terrain

Tilt into 3D and the route becomes a shape: which side of the ridge, how the spur runs, where the pass actually is. Switch between the topo sheet and aerial photography at any time.

Official trails, and the routes hikers map

Government and park-agency trails carry the publisher's own grade and walking time. Named routes from OpenStreetMap fill in what the agencies never drew. Nothing is given a grade it does not have.

  • 405,705 official agency trails — US Forest Service, NPS, swisstopo's full Wanderweg network, DOC New Zealand, France, Norway, Ireland, Czechia, Bavaria, South Tyrol, Tyrol, Slovenia, Parks Canada, BC, Alberta, Ontario, Quebec, Manitoba, NSW, Tasmania, Queensland, South Australia
  • 350,165 named routes, from Te Araroa to the GR network
  • 1,266,930 huts, shelters, campsites and water points
  • Every country on Earth

Plan a trip

Pick two points. Get the whole trip.

Ridgeflow routes on hiking trails, not roads, and times the walk from the gradient — so a 12 km day with a saddle in it is not costed like 12 km of valley floor. Then it tells you where you can sleep.

Distance, time, climb — and the profile

  • Total distance, walking time, climb and descent, at a glance
  • An elevation profile with the high point, low point and range
  • Times tuned separately for hiking and trail running
  • Export the exact line as GPX, or get driving directions to the trailhead
  • Distance, time and arrival stay on the map while you look around

Days, nights and every hut on the way

  • Huts and campsites in walking order, with distance, height and whether they can be booked
  • Multi-day trips split into days by the huts that actually exist
  • Press and hold the map to stay here overnight — the days re-plan around it
  • The longest stretch with nowhere to stay: the day you have to be able to walk
  • Drag the planned line to send the route another way

Tap any hut

Every hut, with what it actually has

Tap a hut for what the agency records: water, toilets, mattresses, cooking, the fee, how to book and the height you will sleep at. Then the things you would otherwise ask at the visitor centre: what is nearby, the week's forecast, and whether your phone will get a signal.

  • Facilities and booking from the Department of Conservation in New Zealand, dated with their age
  • Estimated cell coverage at the hut for each carrier, in New Zealand today
  • A 7-day forecast for the hut itself, not the nearest town
  • A field the source leaves blank says "not listed", never "none"

Weather

The forecast where you'll be, when you'll be there.

A town forecast tells you about the valley. Ridgeflow fetches the weather for each stop on your route, for the day you will reach it, and keeps it on your phone for when the signal goes.

  • Along the route — temperature, rain and wind for the start, every stop and the finish, on the day you get there
  • Offline — a 7-day forecast is saved along the whole line, so it rides with you into dead zones
  • Live rain radar over the map, in 2D or 3D
  • Official warnings — Official severe-weather warnings and avalanche advisories where we carry them, and a plain "none issued" where they don't
  • After dark — told when a plan would finish after civil dusk
  • Overlays — temperature, wind, rain and cloud across the map
Weather along the Routeburn Track on a phone: snow at the start, heavy snow at Lake Mackenzie Hut on Friday, light drizzle at the Divide on Saturday, with temperature, rain and wind for each.

The part we care most about

It tells you when it doesn't know.

Coverage is uneven, and pretending otherwise is how people get hurt. Where an authority publishes closures, avalanche advisories or severe-weather warnings, Ridgeflow shows them. Where it has none, it says so in plain words instead of showing a calm empty map that reads like an all-clear.

Absence is never an all-clear

"No warnings here" and "we don't carry warnings here" are different sentences, and you get whichever one is true.

Data is dated and sourced

Hut and closure information carries the date it was retrieved and the agency it came from, because a month-old notice is not today's conditions.

No invented numbers

If there's no elevation data for a track it says so rather than printing a confident "+0 m" that reads as flat ground.


Anywhere means anywhere

What it costs

7-day trial.Every feature unlocked. A card starts it and nothing is charged until day 7. Then your plan starts, unless you cancel in the app before then.

Make an account with your email address or with Google, then start the 7-day trial: Stripe takes a card, nothing is charged today. Cancel in the app any time before day 7 and you pay nothing. If you don't cancel, your plan starts on day 7.

One plan, every feature: the topo sheet and 3D satellite terrain, the trail data and huts, route planning, offline map downloads, weather along the route. Offline downloads are the honest reason there is a price at all — serving gigabytes of terrain costs real money every month.

Earlier versions of this page said the map would stay free after the trial. From 29 October 2026 Ridgeflow is one plan with a trial that a card starts (7 days since 5 November 2026), and this is the announcement of that change. A route someone shares with you still opens for anyone, with no account.

Questions

Before you go.

Do I need to create an account?

Yes — with your email address or with your Google account, and then a plan. Every plan starts with a 7-day trial: a card starts it, nothing is charged until day 7, and you can cancel in the app before then. A route someone shares with you still opens without any account at all.

Which countries does it cover?

The contour topo map, 3D terrain and community trail data are worldwide. Official agency data exists for a growing list — the United States, Switzerland, France, Norway, Ireland, Czechia, Slovakia, Luxembourg, Slovenia, Germany (Bavaria), Italy (South Tyrol), Austria (Tyrol), Canada, Australia, Hong Kong, Singapore, Taiwan and New Zealand, which has the deepest coverage. Where an area has thin data, the app says so in the Layers panel rather than leaving you to guess.

Is it an app or a website?

It runs in the browser on a phone or a laptop, and installs to your home screen like an app — including working with no connection. An Android build is in progress.

How accurate are the walking times?

They are estimates from distance and gradient, tuned differently for hiking and running. Where an agency publishes its own time for a track, that figure is shown too — and if ours disagrees with theirs by much, you are told both rather than just ours.

Can I trust the closure information?

Treat it as a prompt to check, not a clearance. It is only as fresh as the agency's own feed, it carries the date it was retrieved, and for most of the world no such feed exists at all — which the app states plainly. Always verify locally before you go.

Does it replace a map and compass?

No, and it isn't meant to. It is a planning and navigation aid running on a device with a battery. Carry a paper map, tell someone your intentions, and use your own judgement about conditions.

Where does the data come from?

OpenStreetMap contributors, national mapping agencies and park services, each under its own licence — credited in full at the bottom of this page and inside the app.
