Pozo Azul, located in the municipality of Maisí in Guantánamo Province, stands as one of the most singular natural attractions in Cuba. Situated near the Faro de Maisí — the easternmost point of the country — this geographical formation captivates visitors with its intense, crystal-clear waters, the depth and vivid blue hue of which give the site its name.

The site corresponds to a doline formed by the collapse of a flooded cavern, making it a notable example of karst geological processes in Cuba's eastern region. Pozo Azul rests at an elevation of 1,499 feet (457 meters) above sea level and is surrounded by tropical vegetation, offering a landscape of exceptional appeal to hikers and nature enthusiasts alike.

Pozo Azul holds considerable ecological and touristic value, positioning it as an ideal destination for ecotourism. Recommended activities include hiking, nature photography, geological exploration, and combined excursions with the nearby Faro de Maisí. The transparency of its waters and the scenic richness of the surrounding area underscore its potential as a site of interest for both domestic and international visitors.

Also located in the same region is the Arroyo Pozo Azul, an intermittent watercourse at approximately 430 feet (131 meters) above sea level. This hydrological feature complements the natural appeal of the area and forms part of Guantánamo's broader water system.

Access to Pozo Azul is best approached from Baracoa or Maisí, combining road transportation with hiking. The optimal time to visit is during the dry season, between November and April, when the waters are at their clearest and the trails most accessible. The area lacks developed tourist infrastructure; accordingly, visitors are advised to bring water, food, and basic hiking equipment.

A visit to Pozo Azul can be complemented with excursions to the Faro de Maisí and nearby beaches, allowing for a comprehensive experience at the eastern tip of Cuba. However, the site faces ongoing challenges related to limited accessibility and the need to conserve a fragile natural environment. Visitors are strongly encouraged to avoid pollution and respect local biodiversity in order to preserve this natural heritage.

Despite its singularity, Pozo Azul remains largely unknown outside local ecotourism circles, a reality that constrains its national and international promotion. Increasing its visibility represents a pending challenge for the advancement of sustainable tourism in Guantánamo and for raising awareness of Cuba's natural wonders.
