Guide to Barra Honda: Costa Rica’s Fascinating National Park

Barra Honda National Park is one of Costa Rica’s lesser-known protected areas, yet it offers a fascinating window into the country’s geological and ecological diversity. Located in the Nicoya Peninsula of Guanacaste Province, the park is best known for its extensive system of limestone caves.

The park was established to protect both subterranean formations and the surrounding tropical dry forest. Today, Barra Honda appeals to adventurous travelers, nature lovers, and those seeking a quieter alternative to Costa Rica’s more famous parks. Its dramatic underground landscapes and scenic hilltop views make it a rewarding destination for exploration.

The defining feature of Barra Honda National Park is its cave system, formed over millions of years as rainwater slowly dissolved limestone rock. More than 40 caves have been identified, though only a handful are accessible to visitors. Here’s our comprehensive guide to Barra Honda National Park;

Overview of Barra Honda National Park

Barra Honda National Park is a remarkable natural attraction in northwestern Costa Rica near the Nicoya Peninsula. Covering roughly 5,000 acres, the park is celebrated for its rare geological features and adventurous appeal. It safeguards an extensive limestone cave system filled with stalactites, stalagmites, and intricate mineral formations, including soda straws, cave pearls, curtains, and terraces.

The park’s highest point, Barra Honda Peak, rises about 1,476 feet and is composed of ancient coral reefs uplifted by tectonic activity. Water erosion has carved more than 40 underground caverns through Cerro Barra Honda and neighboring hills. These caves, some reaching depths of over 780 feet, remain largely pristine due to their vertical entrances.

They require climbing equipment, advance permission from the national park authority, and a certified guide. Terciopelo Cave is the most renowned, accessed by a steep ladder or a nearly 60-foot rappel and admired for its dramatic formations. Another crowd favorite is Pozo Hediondo, named after the strong scent of bat guano.

Before their exploration in the late 1960s, the sounds of bats and rising cave vapors even led locals to believe Barra Honda was a volcano. Beyond its subterranean wonders, the park also features well-maintained hiking trails that wind through protected tropical dry forest.

Wildlife in Barra Honda National Park

Wildlife in Barra Honda National Park reflects the richness of its dry tropical forest and the hidden ecosystems within its limestone caves. Above ground, mammals such as howler monkeys and white-faced capuchins are frequently seen moving through the trees. Hikers will also encounter coatis, agoutis, raccoons, armadillos, white-tailed deer, and anteaters roaming the forest floor.

More elusive species, including pumas, also inhabit the park, though they are rarely encountered. The caves themselves are vital refuges for large bat colonies and support unusual underground life, including blind fish and salamanders. Birdlife is particularly impressive, with more than 150 species recorded, ranging from king vultures and parrots to the striking scarlet macaws found in nearby areas.

Best Time to Visit Barra Honda National Park

The best time to visit Barra Honda National Park largely depends on planned activities. December to April is the dry season. The window brings mostly sunny days, minimal rainfall, and comfortable temperatures averaging around 88°F during the day and 70°F at night. It’s the most popular and practical time to explore the park.

Clear skies and lower humidity levels make it ideal for hiking, wildlife spotting, and cave exploration, which is only permitted during this period. May to November is the wet season. The window introduces frequent afternoon and evening rains, with September and October experiencing the heaviest downpours. The park’s annual rainfall is roughly 110 to 130 inches.

While temperatures remain similar to the dry season, high humidity and lush vegetation define this time of year. However, the caves are closed during the wet months because of the risk of flooding. Occasional showers occur year-round, so you should always be prepared for changing conditions. However, the dry season is the best choice for access and activity options, particularly for those interested in spelunking.

Getting to Barra Honda National Park

Reaching Barra Honda National Park is easiest by car, especially for travelers coming from San José. The drive follows the Interamerican Highway north, passing the turnoff for Las Juntas de Abangares before branching left onto Route 18 toward San Joaquín. From there, the route connects to the spur leading to the newer Tempisque bridge, after which the road continues southwest for roughly 10 kilometers.

A right turn toward the villages of Barra Honda, also known locally as Nacaome, and Santa Ana leads to clearly marked signs for the park. The entrance gate opens onto a well-maintained gravel road less than a mile long that leads to the park headquarters, and a four-wheel-drive vehicle is not necessary.

Public transportation is more challenging, as there is no direct bus service to the park. You must first take a bus from San José to Nicoya, with daily departures from Terminal Alfaro at a 2-3 hour interval. The journey takes about 6 hours, and costs around $5.20 with Alfaro Bus. From Nicoya, only one bus per day departs at 12:30 p.m. for Santa Ana. So, plan your trip appropriately if you’re determined to use these means.
