viaTopo plans a hike on the official Swiss national map, and takes it with you.

Tap your waypoints and viaTopo works out the path between them from the federal topographic model, so the line takes the switchbacks of the real trail instead of cutting straight across the slope. It reports the distance, the ascent, the descent and a walking time from the model Schweizer Wanderwege publishes, stage by stage and for the whole route, with the elevation profile under the map.

On the mountain, without a signal
• Save the map for a region, or along the route you drew, and it is kept on your device, ready to read with no signal at all.
• Your position on the map, and the direction you are facing.
• Import a GPX somebody sent you. Export the one you drew through the share sheet.
• Routes are saved on the device. An account is optional, and keeps them on your other devices too.

The map itself
• The swisstopo colour and grey sheets, the winter map, aerial imagery, and a community topographic base.
• Drawn in LV95, the Swiss coordinate system, rather than stretched to fit a global one: the sheet on your screen is the sheet that was surveyed.
• Slope gradient, ski and snowshoe routes, signposted winter trails, hiking-trail classes, wildlife rest areas, and the rest of the federal catalogue, each with its own opacity.

Before you leave
• Trail closures, and the detours published around them.
• Military shooting-danger zones, with the days they fire.
• The alps where livestock guardian dogs are working.
• MeteoSwiss by hour and by day for the point you picked, rather than for the town down in the valley. Rain radar for the last hour, the altitude the snow lies at, and what the automatic stations are measuring right now.
• Swiss Alpine Club huts, with the page each takes bookings on.
• The yellow signposts of the Swiss network, photographed where they stand, so you know the junction before you reach it.
• Public transport stops, with the next departures from each.

Free, and quiet about you
Planning, importing and exporting all work without an account, and nothing you draw leaves the device unless you choose to save it. Your position is read only when you ask for it and is never sent to us. No advertising, no profiling, no tracking, nothing to buy.

French, German, Italian and English, light and dark, following your device or set by hand.

The route search is experimental. It runs on your device rather than on a server, and it says so plainly when it cannot find a way between two points.
