By Car: Follow the directions to Liberia. When you reach Liberia, head straight through the major intersection, following signs to Peñas Blancas and the Nicaraguan border.
To reach the Las Pailas (Las Espuelas) entrance, drive about 5km (3 miles) north of Liberia and turn right on the dirt road to the park. The turnoff is well marked. In about 12km (7 1/2 miles), you’ll pass through the small village of Curubandé. Continue on this road for another 6km (3 3/4 miles) until you reach the Hacienda Guachipelín. The lodge is private property, and the owners charge a small toll to pass through their gate and continue on to the park. Pass through the gate and continue for another 4km (2 1/2 miles) until you reach the park entrance.
Two routes lead to the Santa María entrance. The principal route heads out of the northeastern end of Liberia toward the small village of San Jorge. This route is about 25km (16 miles) long and takes about 45 minutes. A four-wheel-drive vehicle is required. Alternatively, you can reach the entrance on a turnoff from the Interamerican Highway at Bagaces. From here, head north through Guayabo, Aguas Claras, and Colonia Blanca. Though the road is paved up to Colonia Blanca, a four-wheel-drive vehicle is required for the final, very rough 10km (6 1/4 miles) of gravel road.
