Southern Costa Rica is generally considered the better option for bird watching. Most hotels, as well as tourist information centers, will provide bird watching guides, maps and other essentials for bird watching. Do not forget to bring a hat, rain gear, boots, binoculars and camera. In hot areas, an umbrella can be more useful than a poncho or jacket.
Marijuana traffic, distribution and commerce is illegal in Costa Rica.
