If you own either TOPO - Yosemite or TOPO - Sequoia/Kings Canyon,
you can download complete trail files for the John Muir Trail! Click
on the links below to download the files (in two segments, one
for each software package.) I do not know how well they will
work if you happen to have the complete California set. To
order the software sets from REI, click the images to
the right or left.

John Muir Trail North (Happy Isles to Senger Creek)
John Muir Trail South (Senger Creek to Whitney Portal)

NOTE: The files are zipped, and will require decompression
such as WinZip to prepare for viewing.
