Hike a section of the Nakasendo Trail on a 3- or 4-day self-guided tour from Tokyo or Kyoto that includes all rail transport. A series of forested trails and paved village paths linking the two cities comprise the Nakasendo, a trail situated along an ancient network of Japanese highways. Follow in the footsteps of travelers from the Edo period who walked this mountain route via the Kiso Valley. Stop in the best-preserved post towns – known as 'juku' – where you'll stay overnight in local 'minshuku' (guest houses). Traditional Japanese dinners and breakfasts are included.
