Mauritania from Morocco

I crossed the border at the beginning of last year and paid 55€. From the reports I have seen on travel fora, the price has not changed at all. Make sure you have exact change, because the Mauritanian border guards often don’t have change. You don’t need passport photos, they will take your photo there in the office.

Be prepared for a lot of police harassment in Western Sahara. The Moroccan authorities will let you cross the region, but they will often follow you on a motorcycle, or insist that you sleep at certain hotels. They are very nervous that foreign cyclists may actually be human-rights activists concerned about the indigenous Saharawi people.
