Map of Costa Rica: Orientation to Regions
You'll find Daniel Oduber International Airport on the detailed map of Costa Rica just outside of Liberia, which is located just northwest of Guanacaste's center.
At the top left of the map you can see a crescent shaped gulf just above the 'G' in Guanacaste. This is the Gulf of Papagayo, a major development hot spot for Costa Rica resorts.
Down the Nicoya Peninsula, you see the tip belongs to the Puntarenas province. You can actually reach the mainland from the peninsula via ferry in the towns of Playa Naranjo and Paquera to the south. Both ferries cross the Gulf of Nicoya and head to the town of Puntarenas. This is a great way shortcut.
The little peninsula you see at the bottom on the Pacific side of the map of Costa Rica is the Osa Peninsula. The body of water between the peninsula and the mainland is Golfo Dulce, which is lined by the popular destinations of Golfito, Zancudo, and Puerto Jimenez. The Osa Peninsula itself is highly popular for the gorgeous Corcovado National Park which is rich in both flora and fauna; a great place to see wildlife.
