How to Get to Diriá National Park #

The park lies on the Nicoya Peninsula in Guanacaste; the usual access is by car from Nicoya town or the coastal towns of Samara and Nosara. Expect gravel roads near the park; a vehicle with reasonable clearance is recommended. Local guides and small tour operators from nearby towns can arrange transport and trails.

Tips for Visiting Diriá National Park #

  • Visit early morning to catch the most wildlife activity-mammals and birds are far more visible at first light.
  • Hire a local guide from Nicoya or Santa Cruz: trails are poorly signed and guides know seasonal waterholes and viewpoints.
  • Bring insect repellent in the wet season (May-November); some trails can become muddy and slippery.
