The Bivy app has over 20,000 adventures mapped across the United States. These adventures include a detailed path and a description of each.  You can save/download the information for offline use.

To save an adventure to your profile, follow these steps: 

1. Tap on the "Map" screen from the bottom menu bar.
2. Navigate to the adventure (the green, blue, red, and brown pins) you want to save/bookmark.  
   • • You can either tap on the specific pin on the map to open the adventure, or search for the adventure by name using the "Find" bar. If these are not visible, tap the magnifying glass icon in the top-right corner.
3. Once you've selected the specific adventure, press the "Save" icon (next to the "Track" button).
4. A message will appear, giving you the option to download a map for offline use to accompany your adventure details. If you plan to do this adventure offline, it is a good idea to download the map.  

This will download the adventure so you can access and use it when out of cell range or just refer back to it easily.  Once you've saved an adventure, it will appear in your "Profile" screen under the "Saved" tab.
