Guanacaste is Costa Rica's dry northwestern province on the Pacific coast, approximately 215 kilometers northwest of San José. You come here for the beaches of the Pacific coast, for volcanic landscapes like the Rincón de la Vieja, and for the light blue Río Celeste.From November to April, there's hardly any rain here, which makes Guanacaste the country's most reliable beach destination during this time; from May to October, it usually rains daily. The landscape is characterized by pastureland, dry forest, and volcanic ranges; the Area de Conservación Guanacaste in the north is a UNESCO World Heritage site.The capital is Liberia, home to the country's second international airport, the Aeropuerto Daniel Oduber Quirós. From there, you can reach the beaches around Tamarindo as quickly as the national parks inland.
Guanacaste, covering around 10,000 square kilometers, is Costa Rica's second-largest and most sparsely populated province. The territory joined Costa Rica from Nicaragua in 1824 after a plebiscite; the anniversary of this annexation on July 25th remains a public holiday today. Cattle ranching, the culture of the Sabaneros, and the Marimba, the national instrument, shape the province's identity.On the coast lies Tamarindo, the region's most famous beach resort, home to Las Baulas Marine National Park, where Leatherback sea turtles lay their eggs. Inland, the Guanacaste Volcanic Range, featuring Rincón de la Vieja National Park, and further east, the Río Celeste in Tenorio National Park, attract most visitors.Liberia serves as the practical starting point: car rental companies are located at the airport, and the Interamericana connects the city with the north and San José.
The Río Celeste is a glowing light blue river in the Tenorio Volcano National Park in Guanacaste, near the town of Bijagua de Upala in the north of the country.
Tamarindo is Guanacaste's most famous beach resort on the Pacific Coast of the Nicoya Peninsula, about an hour's drive from Liberia International Airport.
Rincón de la Vieja National Park protects its namesake volcanic massif in Guanacaste, about 25 kilometers northeast of Liberia. You come here to hike through tropical forest among fumaroles, bubbling mud pots, and waterfalls.
