Google Maps provides less functionality than the other interactive map.  Check out both of them and decide which you prefer.

This is a simpler map and is the better option if you have a slow connection.

Presently, this is the only interactive map that allows you to show your current location along with trails.  Use the Full Screen button on the upper right corner of the map to open it in a new window (or the Google Maps app if it is installed).  When it opens, you can use the Show Your Location tool.
