There are plenty of GPS track sites on the interenet but these sites seem to have more Indonesian tracks.
They also have an iPhone app for GPS tracking and following routes. Free or membership options.
If you want to geotag your photos so they will show up in the correct location on Google Maps, this software my help.
Alternatively Nikon's ViewNX can quickly Geotag your photos using the gpx log of a track.
Unfortunately you need to have a Nikon Camera registered to use it, although it works with any camera and jpg format.
There may be other camera brands that sell with equivalent software.
