Is it necessary to book hostels in advance?
It is not possible to book public hostels in advance, as they operate on a first-come, first-served basis and prioritize the rotation of pilgrims.
However, private hostels do allow advance reservations. If you travel during the low season, booking is not very necessary, although it is always advisable. In high season, however, it is almost mandatory to book, as you risk not finding accommodation, or finding it far from the stage’s end point.
