Border Crossing

The border between Chile and Argentina is still strictly maintained, but crossing it doesn't present much difficulty beyond getting out your passport and waiting in a line to get the stamp. Most travelers end up crossing the border by bus, which means getting out of the vehicle for 30-45 minutes to go through the bureaucratic proceedings, then loading back in. Crossing by car is also quite manageable (check with your car-rental company for restrictions on international travel). Chilean customs officers are extremely strict about bringing food into the country, especially compared to their Argentine counterparts.
