The most popular in all guides is the middle Camino, going along the N-1110 to Estella.
The original Way bypasses Estella altogether, and leads through Luquin (Albergue Casa Tiago) to Los Arcos through an amazing landscape at the foot of Montejura, lots of it through woods (nice in summer!).
The northern variant (amazing!) leaves Villatuerta by the bakery on the other side of N-1110 at the exit of the town. Brings you to Estella by the new traffic circle - you will walk through the center of the town.
All three variants are very well marked now (from the end of 2019 pilgrimage season).
