You receive a tourist visa from immigration upon your arrival. Campgrounds are also found along this coastline. Day boats go out from La Paz to nearby dive sites year-round, weather permitting. The sky is usually clear and blue, the wind moderate to light, and the sun intense, so don't forget that high SPF sunscreen. The Mexican peso is the official currency, although US dollars are widely accepted in the cities.
Most merchants also accept traveler's checks and credit cards.
