If you've used a phone map before, you've probably got this, but a few controls are worth pointing out:
Where am I?
Tap Locate to show your position. The map follows you as you move. If you pan away, the icon becomes hollow. Tap it again to resume following, or one more time to disable.
Let's go back...
Lost your place? Tap Reset to snap back to the default view.
Customize!
Open the Options menu to adjust labels, change the season, turn on or off difficulty indicators, direction arrows, trail markers, set light/dark mode, and more. (Available toggles vary by map.)
These settings are saved for the next time you load the map.
In here you'll also find a link to make the map install like an app, a view Sharing tool, and more info About the map.
I know it's around here somewhere...
Use the Route key to highlight a route or loop with a single tap. Or hide it out of the way.
Tap Search in the key to go deeper to find the trail or route your friend told you about, a toilet, drinking water, or any other feature along the trail.
Curated, local, and styled like the trails.
Ever wish for a map in your pocket that clearly shows the local riding trails and matches the official map and the signs? That's what these maps get you.
Each map here is built from a snapshot of OpenStreetMap data, layered with other open data, focused on mountain biking, and styled the way the trail system is marked. Curated, built, and used by riders who know these trails.
Trail lines are styled to match the colors used on each park's signs and trail markers.
One-way trails show riding direction arrows, automatically changing on alternating-direction systems.
A season toggle shows winter-only trails such as groomed fat-bike loops.
Anyone, including visitors from out of town, can open the map and ride. No login, no paywall.
No user tracking, no telemetry, no cookies. I don't watch you.
Maps are reviewed by someone who knows the trail before they go live.
Once a map is created it does not change until it is regenerated. For trail managers, no more surprise map changes.
trailmaps.app maps can be installed on your Android and iOS device like an app for easy access and offline use.
Hi, I'm Steve.
trailmaps.app is a personal project site that hosts maps I've made so I can share them with others. The code for making these interactive maps, PDF maps, and some of my other tools, are all open source.
Say hello, request a map, or send a donation.
Creating and hosting these maps costs money. Help pay for some of it.
