Treasure Lagoon is located at east of Boca de Guama, and it’s reached by boat a canal of 4 km (2½ miles) into the lagoon. According to legend, Taíno aboriginals dumped gold and other loot in this lake to hide it from the Spanish. No treasure has ever been found, although Taíno relics have been recovered from the lake and are now displayed in the Guamá Museum. A lifelike recreation of a Taíno village spans across several small islands. This impressive replica has 32 life-size figures of Taínos going about their daily business, was created by Cuban sculptor Rita Longa.

In the Zapata Peninsula, the sea has formed a series of natural pools by entering through underwater caves, creating the largest flooded cavern in Cuba. It has large colonies of different kinds of coral, plus a great variety of yellow-, violet- and orange-colored barrel-, tube-, basket-and cup-shaped sponges. In addition, there are many kinds of marine plants, large gorgonians and many tropical fish. Experienced, well-equipped divers can follow a 25-meter (83-foot) tunnel through the limestone leading out to the sea. There's no need for boats as the dive area is close. Night dives can also be arranged. The on-site restaurant is open until 5 and specializes in shrimp and lobster. 

The Zapata National Park was declared a UNESCO Biosphere Reserve. The park covers an area of 4,520 km2 (1,641 miles2) encompassing mangroves, cactus, dry woods, savannahs, salt pans and forest, providing habitat for reptiles, mammals, and many birds. Bird-watchers from all over the world flock to this national park in hopes of feasting their eyes on some 190 bird species, including 21 endemic species such as the eponymous Zapata Rail and Zapata Wren, along with the red, white, and blue tocororo—Cuba's national bird and the zunzuncito (Bee Hummingbird), the smallest bird in the world. Even if you're not a passionate birder, you can still enjoy watching a mass of wading birds—flamingos, wood storks, sandhill cranes—feeding here. There are many marine and freshwater fish in the area, including Manjuaríes, which are considered to be living fossils because of the primitive nature of their bodies. Many pre-Columbian archaeological remains have been found on the Zapata Peninsula, and the region’s history also includes the narrow channels that early inhabitants dug to facilitate river travel. The main access to the park is via Playa Larga at the head of the Bahía de los Cochinos. 

Fiesta Campesina is a casual farm-cum-zoo where visitors can see two of Cuba's distinctive animals: the manjuarí, a primitive water creature with an alligator-like head and a fish body, and the jutía, a large-eared, muskrat-like tree rat, once prized for guajiro stews. Around the farm yard there are other animals such as: deer, peacocks, rabbits, ducks, and guinea fowl. There are souvenir kiosks scattered around, and an open-air restaurant mostly set up for tour-group buffets. At the guarapa bar, you can buy a glass of fresh-pressed cane juice, with or without rum. The musical entertainment is provided by a caged Cuban Bullfinch, a small black bird, so prized for its song that Cubans organize bird-song competitions.
