Juan Castro Blanco National Park

Juan Castro Blanco National Park (Parque Nacional Juan Castro Blanco) is a 14,258-hectare protected area in the northern highlands of Alajuela Province, established in 1992 to protect critical watershed areas and cloud forest ecosystems. The park sits between 700 and 1,550 metres elevation and encompasses the headwaters of several important rivers that supply water to the northern plains and Central Valley.

The park is one of the least-visited national parks in Costa Rica, offering a pristine wilderness experience for adventurous travellers. The cloud forest is dense and rich in biodiversity, harbouring quetzals, toucans, howler monkeys, and a diverse array of orchids and ferns. The terrain is rugged and trails are limited, making this a destination for experienced hikers and nature enthusiasts.

The climate is cool and wet year-round (15–22 °C), with heavy rainfall especially from September to November. The park has minimal infrastructure — no visitor centre, limited signage, and no maintained trails in some sections. A local guide is strongly recommended.

By Plane

Juan Santamaría International Airport (SJO IATA) is approximately 80 km south (2 hours by car).

By Car / Road

From Alajuela, take Route 1 north toward Naranjo, then Route 707 north toward Zarcero, and follow local roads toward the park — approximately 80 km, 2 hours. Access roads are unpaved and can be difficult during the rainy season. A 4x4 vehicle is essential. No public transport serves the park directly.

There is no internal road system in the park. All exploration is on foot via rough trails. Hiring a local guide from Zarcero or the surrounding communities is strongly recommended for navigation and wildlife spotting.

• Cloud forest — Dense, moss-draped forest with towering trees, epiphytes, and a rich understory. The forest is home to resplendent quetzals (best spotted December–April during nesting season).

• River headwaters — Several pristine rivers originate within the park, flowing through deep forest gorges.

• Wildlife — Howler monkeys, white-faced capuchins, coatis, peccaries, and a remarkable diversity of bird species including quetzals, bellbirds, and toucans.

• Volcanic terrain — The park encompasses volcanic formations from the Tilarán range, with interesting geological features.

• Hiking — The park has limited but rewarding trails through primary cloud forest. Trails are rough, steep, and often muddy. Allow a full day for any significant hike.

• Birdwatching — Excellent for highland species including resplendent quetzals, three-wattled bellbirds, and numerous hummingbird species.

• Photography — The pristine cloud forest and misty atmosphere offer dramatic photography opportunities.
