La Marta

La Marta Wildlife Refuge is a protected area of 1,518 hectares located in the Pejibaye district of Cartago province, Costa Rica, distinguished as the first private wildlife refuge established in the country. Situated near Turrialba, approximately 60 km east of San José, the refuge encompasses 60% primary forest and 40% secondary forest on the Caribbean slope of the Talamanca foothills. La Marta forms part of the broader protected landscape connecting to La Amistad International Park—a UNESCO World Heritage Site—and contributes to the ecological integrity of the Turrialba-Chirripó biological corridor. The refuge is managed as both a conservation and ecotourism facility, offering access to an extensive 20-trail network totaling approximately 18 km through diverse forest types.

La Marta Wildlife Refuge supports an exceptional diversity of mammals, including large felids such as jaguars and ocelots that use the refuge as part of their broader territory in the Turrialba corridor, as well as tapirs, giant anteaters, sloths (both two-toed and three-toed), kinkajous, and collared peccaries. The refuge's combination of primary and secondary forest across different successional stages creates habitat diversity that supports over 300 bird species including numerous highland forest specialists, raptors, and the great green macaw. Amphibians are particularly diverse, with multiple tree frog species, glass frogs, and salamanders inhabiting the moist forest floor and streams. The refuge's streams support freshwater fish and aquatic invertebrates, and serve as important water sources for mammal populations.

The forests of La Marta Wildlife Refuge are characterized by remarkable richness in timber trees, palms, and epiphytes spanning multiple forest layers. Canopy trees include species of Terminalia, Cedrela tubiflora (cedro), Licania arborea, and various palms that reach heights of 30–40 meters. The forest floor and subcanopy are rich in tree ferns, selaginellas, and ground orchids, while the canopy itself is festooned with hundreds of species of epiphytic bromeliads, orchids, lichens, and mosses. The refuge contains areas of old-growth primary forest with enormous veteran trees draped in moss, alongside recovering secondary forest in various stages of succession that together provide a comprehensive representation of Caribbean slope forest dynamics. Medicinal plants recognized by indigenous communities are catalogued within the refuge.

La Marta Wildlife Refuge sits on the Caribbean-facing slopes of the Talamanca foothills, in a zone of complex geology where the igneous intrusions of the Talamanca range meet the sedimentary and volcanic rocks of the Caribbean lowlands. The terrain is characterized by steep ridges, stream-carved valleys, and waterfalls formed where resistant rock bands create knickpoints in the drainage network. Soils are generally deep, weathered, and rich in organic matter, supporting the dense forest growth characteristic of high-rainfall Caribbean slope environments. The high precipitation and year-round moisture lead to significant weathering and soil development, creating the nutrient-cycling conditions that sustain the refuge's diverse tree community.

La Marta Wildlife Refuge experiences a wet Caribbean tropical climate with high rainfall distributed throughout the year, characteristic of the Turrialba region. Annual precipitation exceeds 3,000 mm and can reach 4,000 mm, with no true dry season—only relative dry periods in February–March and September–October when rainfall is somewhat reduced. Temperatures range from 18°C to 26°C at the refuge's elevations, with the cloud cover and high humidity keeping conditions comfortable but damp year-round. The refuge is frequently shrouded in cloud or mist, particularly in the mornings and afternoons, contributing to the atmospheric quality of the forest experience and supporting the dense epiphytic vegetation.

The Turrialba region has been inhabited since pre-Columbian times, with the Guayabo archaeological site—Costa Rica's most important pre-Columbian monument, located near Turrialba—documenting complex indigenous societies that flourished from approximately 1000 BCE to 1400 CE. The Pejibaye district where La Marta is located takes its name from the pejibaye palm (Bactris gasipaes), a culturally important food plant cultivated by indigenous peoples throughout the region. European settlement of the Turrialba valley began in the colonial period and intensified in the 19th century with coffee cultivation and later sugarcane. The establishment of La Marta as a private wildlife refuge represented a conscious decision by its owners to dedicate the land to conservation rather than continued agricultural use.

La Marta Wildlife Refuge was established as Costa Rica's first private wildlife refuge under the country's wildlife conservation law, which recognizes and incentivizes private landowners to formally protect biodiversity-rich areas on their properties. The refuge's 1,518 hectares were declared a wildlife refuge to provide legal protection for the primary forest and to formalize a management framework for ecotourism and research activities. The establishment of La Marta contributed to the connectivity of protected lands between the Turrialba area and the La Amistad International Park, which was jointly designated a UNESCO World Heritage Site by Costa Rica and Panama in 1983 for its extraordinary biodiversity and cultural significance.

La Marta Wildlife Refuge features 20 interconnected trails totaling approximately 18 km (11 miles), ranging from short interpretive walks to full-day wilderness routes through primary forest. Waterfalls are among the most popular attractions, with several dramatic cascades accessible via forest trails, particularly during and after the rainy season. Night hikes led by trained naturalist guides reveal the refuge's nocturnal wildlife, including frogs, night insects, sleeping birds, and occasionally large mammals. Birdwatching tours focus on Caribbean slope forest specialists and rarities, with the great green macaw a particularly sought species. The combination of jaguar presence and primary forest makes La Marta one of the more accessible locations in Costa Rica for experiencing a functioning, intact tropical forest ecosystem.

La Marta Wildlife Refuge is located in Pejibaye, Cartago, approximately 60 km east of San José via Route 10 toward Turrialba. The refuge offers visitor facilities including a reception area, guided tour services, and camping options for multi-day stays. Guided hikes, birdwatching tours, and night walks can be arranged directly with the refuge administration. The town of Turrialba (approximately 15–20 km from the refuge) provides a full range of accommodation, restaurants, and services. The refuge is accessible year-round, though the Caribbean climate means visitors should always be prepared for rain regardless of season. The best months for wildlife observation vary by species, but the relative dry periods of February–March and September–October offer somewhat more comfortable trail conditions.

La Marta Wildlife Refuge plays a critical role in maintaining biological connectivity between the Turrialba valley and the La Amistad World Heritage Site, serving as a wildlife corridor for species including jaguars and tapirs that require large territories spanning both protected and unprotected landscapes. The refuge's private management model demonstrates that economically sustainable ecotourism can generate sufficient revenue to fund conservation activities, providing a replicable model for private land conservation in Costa Rica. Research activities within the refuge contribute to scientific understanding of Caribbean slope forest ecology, tropical mammal population dynamics, and amphibian diversity. The refuge participates in regional conservation planning through SINAC's Amistad Caribe Conservation Area, coordinating with neighboring landowners and protected areas to strengthen corridor connectivity.
