Big Sur Trailmap Geospatial PDF Maps
Many trail/camp locations on
USGS/USFS/WildernessPress/NationalGeographic/Garmin maps of the Big Sur Ventana & Silver Peak Wilderness Areas are incorrect -
these geospatial PDF maps from the on-line Big Sur Trailmap provides accurate trail and camp locations
based on local knowledge (mostly GPS'd), and also locally-known "use
trails", water sources, waterfalls, and other features in the Ventana
and Silver Peak Wilderness areas and in Big Sur state parks.
Smartphone GPS apps Avenza Maps (free for 3 maps, else $30/yr)
and Mappt ($30/yr)
can utilize these geospatial PDF files (more info)
Also Adobe Acrobat Reader
for viewing - but it is not a GPS app and cannot display your current location
Note: these files are too large for some PDF apps. They were useable in Adobe Reader on desktop and android smartphone - but I've also had difficulties on smartphones.
If you know of other apps with the same capability, let me know so they can also be linked here
These geospatial PDF maps are new - if you notice a problem, please let me know so it can get fixed!

(1) To app directly: "Copy" desired file URL from table below (using long press), then "Paste" into app's import page (for Avenza, use "+" icon on "My Maps" page).
- OR -
(2) To smartphone cache/directory:
left click on ID of desired map, then use smartphone "Import"
to import downloaded file into app.
(Note: this may fail if the smartphone wants to automatically display the PDF file, as iphones are wont to do, since the files
are too large for some PDF apps)
