Use chloroquine, beginning one week before and Continuing two weeks after your visit. Chloroquine is reputedly safe for pregnant women and children. Food Like so much about Costa Rica, food runs the gamut from traditional fare to modern fast food, from rice and beans to hamburgers and french fries. Just about everything you might want can be found in main towns, including natural foods like peanutbutter, granola, whole wheat bread, and fruit juice. Tortillas are sold packaged and make a good bread substitute.
Fresh produce is excellent and sold at markets in large towns or produce shops in smaller villages.
Variety is good, including a broad range of tropical fruits. Food shops are easy to find, with at least two or three even in the smaller towns. For an inexpensive meal out, find a small restaurant frequented by locals. Only lightweight clothing is needed throughout the country with the exception of something warmer for a visit to the cloud forest and higher elevations. Bring lightweight rain gear during the rainy season.
