This 2,896-meter (9,500-foot) volcanic summit is the highest point in Braulio Carrillo National Park. Dormant for 300 years now, Barva is massive: its lower slopes are almost completely planted with coffee fields and hold more than a dozen small towns, nearly all of which are named after saints. On the upper slopes are pastures lined with exotic pines and the occasional native oak or cedar, giving way to the botanical diversity of the cloud forest near the top. The air is usually cool near the summit, which combines with the pines and pastures to evoke the European or North American countryside.
Barva's misty, luxuriant summit is the only part of Braulio Carrillo where camping is allowed, and it's a good place to see the rare resplendent quetzal early in the morning. Because it's somewhat hard to reach, Barva receives a mere fraction of the crowds that flock to the summits of Poás and Irazú. A two- to four-hour hike in from the Barva ranger station takes you to the main crater,
which is about 162 meters (540 feet) in diameter. Your efforts should be rewarded by great views (as long as you start before 8 am, to avoid the mist). The almost vertical sides of the crater are covered in sombrillas de pobre, a plant that thrives in the highlands, and oak trees laden with epiphytes (nonparasitic plants that grow on other plants). The crater is filled with an otherworldly black lake. Farther down the track into the forest lies a smaller crater lake. Bring rain gear, boots, and a warm shirt. Stay on the trail when hiking anywhere in Braulio Carrillo; even experienced hikers who know the area have lost their way up here, and the rugged terrain makes wandering through the woods very dangerous. In addition, muggings of hikers have been reported in the park. (This is the closest national park to San José and its attendant urban problems.) Go with a ranger.
For access to the volcano, start from Sacramento, north of Heredia. North of Barva de Heredia the road grows narrow and steep. At Sacramento the paved road turns to dirt, growing worse as it nears the Barva ranger station. We recommend a 4WD vehicle, especially during the rainy season. From the ranger station you can take a 4WD vehicle over the extremely rocky road to the park entrance (dry season only), or hike up on foot.
