1. Shimanami Kaido, Japan


A charming day-long seaside cycling route
Arguably Japan’s best and most popular cycling route, this 70-kilometer inter-island trail goes from Onomichi City to Imabari City. Perfectly paved, the route’s pathways are clearly marked with a blue line, so it’s virtually impossible to veer off course. But what’s all the fuss about? This route connects Seto Inland Sea’s six cultural islands via seven unique bridges. And in classic Japanese form, everything along it is well set up, from excellent public toilets to Instagrammable cafes, historic temples and uber-clean guesthouses.
Difficulty: Easy; this is one for the whole family, with no real change in elevation and plenty of places to rest.
