Cayo District
The Cayo District is mostly an agricultural district. The chief crops are citrus, (oranges, grapefruit, and tangerine), as well as bananas.  Recently oil was found in Spanish Lookout and is now in production.  In addition to the ruins listed above there are several other important nature reserves including two National Parks, Blue Hole (park) and Guanacaste National Park. Ecotourism is also an important part of the region's economy.
