Hiking Trails by City.

Community-mapped routes with real lengths, in kilometres and miles — and an honest account of what the data does not cover.

Named hiking routes near 8 US cities — 163 of them — each with its length in kilometres and miles, computed from OpenStreetMap geometry rather than copied from a guidebook.

Which cities do these trail guides cover?

These guides cover Asheville, Boulder, Denver, Phoenix, Portland, Salt Lake City, San Diego and Seattle — 8 cities, 163 named hiking routes in total. Each city page lists the routes OpenStreetMap has mapped within a set radius of the centre, sorted shortest to longest, with lengths in both kilometres and miles.

How are the trails on these pages chosen?

Every route is a named hiking relation in OpenStreetMap inside a fixed radius of the city centre, between 1 and 60 km long, with no guarantee of public access, difficulty or day-hike suitability. Where a city has more than 30 of them the page keeps the 30 shortest and says on the page that it is capped.

Do these pages show trail difficulty?

Only where OpenStreetMap actually grades a route on the SAC hiking scale, which today is almost nowhere. Rather than fill a column with dashes or invent ratings, each city page says plainly that no grade is mapped and points you at the land manager for the trail you choose.

Can you record and share a hike from these trails?

Yes. TrailsPals records your route on your iPhone and gives someone you trust a link showing your last synced position, when it was recorded, and when you said you would be back — they install nothing. Out of coverage the track keeps recording and syncs when signal returns.

Before you go

Pick the length first, then read up: our day-hike safety checklist covers what to do before you leave, the beginner gear checklist covers what goes in the pack, and what to do if you get lost covers the part nobody plans for. If someone at home wants to follow along, live location sharing explains what they actually see, and the hiking safety app page covers expected-return times and check-ins. Recording the walk itself is its own guide.
