Pilgrimages aren’t only for the religious. They can be fun and inspiring, challenging yet rewarding and don’t necessarily involve prayer. The best ones, however, do involve a bit of a trek.

A hot spring hotel to soothe aches and pains at the end of the day is never far away. This is one of only two UNESCO-recognized pilgrimage walks, after the Camino de Santiago in Spain.

Here, the apostle St. James is said to be buried. There are a number of different routes to the final destination – these can take anywhere from a week to months. The French Way is one of the most popular and has been declared part of a UNESCO World Heritage Site.

Beckett quickly became known as a miracle maker and was later canonized. The main pilgrim route that ran between Winchester and Canterbury is sadly no longer a viable walking trail due to traffic. The modern pilgrim can follow the St. Swithun’s Way to Farnham and then the North Downs Way to Canterbury.

Char Dham (India) Char Dham refers to four pilgrimage sites in the Uttaranchal state at the foot of the Himalayas. These sites are particularly important to Hindus, who aim to visit them at least once in their lifetime. For the non-religious, this journey is an excellent way to learn more about Indian culture and tradition and to experience the natural beauty of the country. More than 250,000 visitors from around the globe make the trip annually.
