However, it is also the most popular park to visit. It is located on the central pacific coast, in the province of Puntarenas. There is a paved road from Quepos which leads you to the center of the village and the main beach. From there you can enter park by walking behind the souvenir shops, crossing a bridge, and paying a small fee at the park entrance. The trails inside the park are very well maintained, and fairly easy to hike. You will find people of all ages hiking through the park and at the end, you will find this gorgeous beach.
