What route does Gawain follow

Gawain rides away from Camelot and spends months traveling through a rough, unfriendly, and godless land. Often alone, Gawain has no friends but his horse and talks to no one but God. On Christmas Eve, after toiling through a daunting wood, Gawain beseeches the Lord and Mary to guide him to some haven where he may attend mass and properly pray on Christmas morning. Almost immediately, Gawain stumbles upon a moated fortress, a beautiful castle with strong defenses and intricate architectural flourishes.
