This generosity of nature has facilitated diverse activities for the visitor that include horseback riding through natural scenarios; canopy tours, water sports, hiking, mountain biking and wildlife observation. The region combines the fertile plains of Guatuso, San Carlos and Sarapiquí with the volcanic mountain ranges of Guanacaste and Tilarán.

One of the main attractions is the Arenal volcano, a perfect cone of 1633 meters of altitude (5.307 Ft), in constant activity that offers the visitor a fireworks spectacle with eruptions and lava. At its base, the Arenal reservoir, an artificial lagoon of 87 kilometers of longitude, characterized by its scenic beauty, constitutes one of the best places in the world to practice windsurfing, thanks to winds that reach 72 kilometers per hour. It is also center of other water sports activities as are boat rides and sport fishing.

The Tabacón River that runs along the vicinity of the volcano, is the source of thermal waters that, in public and private areas, offers visitors a delicious therapeutic relaxing bath. The volcano and its bordering forests have the category of National Park and trails are available that allow exploration of the surrounding areas of this colossus.

Another place of great beauty is the Cerro Chato, an extinct volcanic crater crowned by a beautiful blue green colored lagoon, which is also part of the Volcán Arenal complex. Nearby, one can also admire the 70 meters high La Fortuna waterfall. In the cloudy summits of the Tilarán Mountain range you can find the town of Monteverde, well known for its biological reserve of the same name, which protects species like the quetzal and the bell bird.

Areas of great biodiversity like Sarapiquí are also source of scientific investigation and the country last haven of endangered species such as the green macaw.
