Mountain bike maps that match the trail.

Better maps from your fellow riders.

Built to use on the trail.

If you've used a phone map, you already know most of this. A few controls are worth pointing out:

Where am I?

Tap Locate to show where you are. The map follows you as you ride, and the screen stays on if your device supports it.

Pan away and the icon turns hollow. Tap it to follow again, or tap once more to turn it off.

Let's go back...

Lost your place? Tap Reset to snap back to the default view.

Customize!

Open Options to change labels, the season, difficulty markers, direction arrows, trail markers, light or dark mode, and more. The choices vary by map, and they're saved for next time.

Options is also where you install the map like an app, Share your current view, and read About the map.

I know it's around here somewhere...

Tap a route in the Routes key to highlight it. Hide the key when you don't need it.

Tap Search in the key to find the trail your friend told you about, parking, a trailhead, toilets, water, or anything else along the way.

Curated, local, and styled like the trails.

Each map starts from OpenStreetMap and other public data. Riders who know the trails then plan it, check it, and style it the way the trail system is marked.

Color-matched to signage

Trails use the same routes and colors as the signs and markers.

Direction arrows

One-way trails show their riding direction. On alternating-direction systems, the arrows switch automatically.

Winter mode

A season toggle shows winter-only trails, like groomed fat-bike loops.

Free and private

Anyone can use the maps, with no account. No tracking, no telemetry, no cookies. I don't watch you.

Static

A map changes only when it's rebuilt. Trail managers get no surprise edits from crowdsourced data.

Works offline

Install any map like an app. It keeps working without a signal.
