New GIS App Instructions

SWTrails introduces a mobile application that lets you follow your favorite trails on a mobile device.

As part of our GIS mapping initiative, SWTrails is happy to announce a mobile mapping option for SWTrail Routes! Searchable maps that include markup and measurement tools will help you to easily find your way. The four steps outlined below will have you out there exploring SW Portland with your mobile device guiding you along in no time!


“Explorer for ArcGIS” in the application store for your type of device. The download is free; however, data charges vary depending on your data plan. Click the link below for your device type to get started:

Apple App Store
Google Play
Amazon AppStore


Once the application is installed, you can access SWTrail published maps from your mobile device. Content published to ArcGIS online, and shared publicly, is accessible through the Explorer app. To find content published by SWTrails search for keywords such as: “SWTrails” or “4T Trail”. Maps with these keywords will show up on your screen below the search bar.


After you have found a map of an area you are interested in, touch it on the screen to open it. You will be able to zoom or pan to the area you are exploring. Make sure that your location tracking is turned on so that your device can pinpoint your location.


There are over 45 miles of established urban trails in SW Portland for you to explore. With the app open and running, you are now able to view interactive SWTrail Routes on your mobile device. Check back periodically as we are updating and adding new content.

Please note: SWTrails is not liable for any use of or reliance upon this map or data, or any information contained herein.
