Sucio River

The Sucio River (Spanish: Ro Sucio, meaning "filthy river") is a Costa Rican river. The river's name comes from sulfur deposits on the Iraz Volcano, which give the water a brownish hue. It is a San Juan River tributary. The Sucio River originates half a kilometer from the summit of the Iraz Volcano and flows into the San Juan River, then into the Caribbean Sea, where it meets the Sarapiqu River near Boca Rio Sucio.

The Chirripo Norte River, a tributary of the Colorado River, is formed when one of the Sucio's branches joins the Patria River. The Sucio River is one of the most beautiful and distinctive rivers of Costa Rica. Because of the special color of the river, it has attracted a large number of tourists to visit.

Visitors often take pictures or participate in water sports here. Both sides of the river are large and small rocky beaches, so visitors need to be very careful if they want to move on it. On one side of the river is a forest of tall trees, which is very cool in the hot season. This is considered one of the longest rivers in Costa Rica.
