Parque Nacional Guanacaste is located in northern Guanacaste, adjacent to Parque Nacional Santa Rosa (with which it shares administration under the Área de Conservación Guanacaste) — a large, lightly visited park of dry tropical forest transitioning to rainforest depending on altitude.
**Three sectors, each distinct**:
**How to visit**: unlike a park with direct entrance, visits to the Maritza and Pitilla sectors **are coordinated first from the Santa Rosa sector** — it is not a "arrive and pay at the ticket office" entry.
**Fee**: ₡1,100 for nationals/residents (confirm the current fee for non-residents directly, as no verified amount was found for this entry).
**Contact**: phone 2666-5051, WhatsApp 8886-9510, email ecoturismo@acguanacaste.ac.cr — the best first step before planning the visit, since entry must be coordinated.
Note: for the historic sector of Santa Rosa (the Casona), see the separate entry for Parque Nacional Santa Rosa — it is a sector with its own fee and schedule, administered under the same Área de Conservación Guanacaste but as a distinct park.
