Tempisque River
The Tempisque River It belongs to the Pacific Ocean Slope. It is the third longest river in the country, after the Río Grande de Térraba and the Reventazón River. The Tempisque is the largest river in Guanacaste, giving life to this Costa Rican province, as its course runs through a large part of the territory. This giant river is born in the Guanacaste mountain range , on the slopes of the Orosí volcano, and is called the Tempisquito River. It runs for about 144 km in a south and southeast direction through the province of Guanacaste, bordering the Nicoya Peninsula, until it empties into the bottom of the Gulf of Nicoya, an inlet of the Pacific Ocean.
Before emptying into the ocean, the Tempisque River drains the low, swampy area that characterizes Palo Verde National Park. Its main tributaries are the Bebedero, Colorado, Liberia, and Salto rivers. The stretch of river between its mouth and the town of Bolsón is navigable, for approximately 36 kilometers. Important Guanacaste cities such as Liberia, Santa Cruz, and Filadelfia lie on its banks or those of its tributaries.
