The most popular route up Takao-san is Trail No 1, which is paved all the way and passes by all the major points of interest. If you're after more of a walk-in-the-woods experience, we recommend hiking up the lovely Trail No 6, and descending via Trail No 1. If following this route, wear sturdy shoes as there are some stream crossings and places where the trail is narrow or slippery. You can also take a funicular railway up the mountain from Takaosanguchi station, and hike back down.
