El Valle

Parque Natural Regional El Valle is a 2,442-hectare (24.42 km²) protected area in Boyaca department, Colombia, declared in 2016 and managed by the Corporacion Autonoma Regional de Boyaca (Corpoboyaca). ^[1] The park straddles the municipalities of Arcabuco and Combita in the Eastern Cordillera of the Colombian Andes, a short distance from the historic towns of Villa de Leyva and Tunja. It conserves high-Andean forest and paramo ecosystems and forms part of the broader Iguaque-Merchan conservation corridor, an interconnected chain of reserves protecting the headwaters and biodiversity of central Boyaca. The park safeguards strategic water sources that supply surrounding rural and urban communities.

El Valle's high-Andean forests and paramo shelter a representative community of central Boyaca fauna. Mammals reported for the area and the surrounding Iguaque corridor include the spectacled bear, white-tailed deer, paca, tayra, and various small carnivores, among 23 mammal species recorded across the corridor. ^[1] Birdlife is especially rich, with 83 bird species recorded, encompassing tanagers, hummingbirds, flowerpiercers, and high-Andean specialists frequenting the forest edges and paramo shrublands. By linking with neighbouring protected areas, El Valle helps maintain habitat connectivity that supports wider-ranging species moving through the Iguaque-Merchan corridor.

The park protects a mosaic of high-Andean forest and paramo vegetation typical of the Eastern Cordillera between roughly 2,800 and 3,500 metres. Forested slopes feature encenillo (Weinmannia), oaks, gaque, and other montane trees draped in mosses, orchids, and bromeliads, with dense Chusquea bamboo in the understorey. Above the treeline, paramo communities are dominated by frailejones (Espeletia), tussock grasses, and cushion plants adapted to cold and high solar radiation. These plant communities are central to the park's hydrological function, capturing fog and rainfall and feeding the streams that descend toward Arcabuco, Combita, and the wider region. ^[1]

El Valle sits within the Eastern Cordillera of Colombia, a range built largely of folded and faulted sedimentary rocks—sandstones, mudstones, and limestones—deposited in ancient marine basins and later uplifted during Andean orogeny. The terrain is mountainous and dissected, with ridges, valleys, and escarpments shaped by tectonic deformation and long-term erosion. Soils derived from these sedimentary substrates, combined with the organic-rich soils of the paramo, give the area its sponge-like capacity to store water. The park's elevated ridges form part of the divide that channels water into the surrounding valleys near Villa de Leyva and Tunja.

The park experiences a cool, humid high-Andean climate that grows colder with elevation, with average temperatures generally ranging from around 6 to 14 degrees C and frequent frost in the highest paramo. Rainfall follows a bimodal pattern, with wetter months typically around April-May and October-November separated by drier interludes. Persistent mist and low cloud are common in the montane forest, sustaining high humidity that is essential to the park's water-regulating role. These cool, moist conditions support the slow accumulation of organic soils and the year-round flow of the park's headwater streams.

The region around El Valle has been inhabited since pre-Columbian times by the Muisca, whose territory encompassed the high plateaus of Boyaca and centred on important settlements near present-day Tunja and Villa de Leyva. After Spanish colonization, the area developed into one of Colombia's historic agricultural heartlands, and the nearby colonial town of Villa de Leyva remains a celebrated heritage site. The municipalities of Arcabuco and Combita, which contain the park, are rural communities engaged in farming and livestock raising, and their inhabitants depend directly on the forests and paramos of El Valle for the water that sustains their fields and aqueducts.

Parque Natural Regional El Valle was declared through Acuerdo 025 of December 2015 by Corpoboyaca, formally inaugurated in January 2016, as part of an effort to expand the network of protected high-Andean ecosystems in central Boyaca. ^[1] Its establishment was motivated by the need to conserve remnant forest and paramo and to protect strategic water sources for the surrounding municipalities. By formalizing protection over roughly 2,442 hectares, the designation strengthened the Iguaque-Merchan corridor, knitting El Valle into a regional system of reserves intended to preserve biodiversity and ecological connectivity across the upper Boyaca highlands. ^[2]

El Valle's appeal lies in its accessible high-Andean scenery of cloud forest and paramo set close to two of Boyaca's major tourist destinations, Villa de Leyva and Tunja. Visitors are drawn by birdwatching, nature walks, and the opportunity to experience frailejón-studded paramo and montane forest within a short drive of historic colonial towns. The park can be combined with visits to the nearby Iguaque sanctuary and other attractions of the Villa de Leyva area. As a relatively young regional reserve, its trail network is modest and exploration is best undertaken with local guides familiar with the terrain around Arcabuco and Combita.

The nearest town to El Valle is Arcabuco, about five kilometres away, which together with Combita provides the main access points; the regional hub of Tunja and the tourist town of Villa de Leyva are both within easy reach. Roads to the park are largely secondary routes, and reaching the higher forest and paramo may require travel on foot or by sturdy vehicle. Formal facilities within the park are limited, so visitors typically base themselves in Arcabuco, Villa de Leyva, or Tunja for lodging and services and coordinate access with Corpoboyaca or local community organizations. ^[1] Its location near a well-developed tourism circuit makes the park comparatively easy to incorporate into a regional itinerary.

Conservation at El Valle focuses on protecting high-Andean forest and paramo and the water resources they regulate for central Boyaca. As part of the Iguaque-Merchan corridor and managed by Corpoboyaca, the park contributes to maintaining habitat connectivity for species such as the spectacled bear across a fragmented landscape. Principal threats include agricultural expansion, cattle grazing into paramo, and clearing of remnant forest. Management emphasizes safeguarding water catchments, restoring degraded areas, and working with the farming communities of Arcabuco and Combita to encourage sustainable practices that reconcile rural livelihoods with the protection of these sensitive high-mountain ecosystems. ^[1]
