Sloths of Costa Rica show some of their most fascinating behaviors at night, especially the two-toed sloth species that are naturally nocturnal and rely on darkness for feeding, movement, and protection. After sunset, sloths often leave their daytime sleeping positions and begin climbing through the canopy, searching for tender leaves, flowers, and young shoots that form the bulk of their diet. Night tours guided by wildlife experts provide travelers with special lighting and techniques that help them observe sloths without causing stress or interrupting natural behavior. Visitors may notice sloths moving more frequently, grooming themselves, or exploring different branches to maintain safe sleeping locations for later in the night. Two-toed sloths tend to be more agile and active after dark, showing behaviors rarely seen during slow daytime movements. Guides explain how sloths use their strong grip, curved claws, and exceptional balance to navigate tree canopies under low-light conditions. Some tours also highlight ecological relationships between sloths and nocturnal insects, algae, fungi, and other organisms that interact with the sloth’s fur ecosystem. Nighttime conditions amplify rainforest sounds such as frog calls, insect rhythms, and rustling leaves, giving travelers an immersive sensory experience. Travelers often pair night sloth tours with nocturnal frog tours or night hikes to maximize wildlife sightings. Experiencing sloths at night gives visitors a deeper understanding of the species’ natural patterns and adds a magical, intimate component to Costa Rica’s wildlife exploration.
