You don't actually have to walk bare foot, although, as you can see, quite a few people do.
The closing date for those who want to walk the 55 miles from Ely to Walsingham is fast approaching. It is Mon 15th August. Don't leave it too late!
For those not intending to walk, it is quite possible to attend as a day visitor. The Mass at Walsingham is at 2pm on Sunday 28th August, and it is followed by a procession along the holy mile, ending in the Abbey grounds fir final devotions.
Day visitors can just turn up, but those undertaking the three day pilgrimage must book in on the LMS website.
