There are two major rivers in the Nosara area, the Montana and Nosara. Costa Rica law bans development on the banks of waterways, so both rivers are pristine. The Rio Montana has mangrove trees along its banks that are essential in a tropical environment because they help to stabilize the soil. Also, Mangroves have very elaborate root systems that help to support the tree and to maximize nutrient intake. This river shares a common boca (Spanish for mouth) with the Rio Nosara. This means that they both flow into the ocean at the same point. The Rio Nosara is the largest river is the Nosara area. A major road in the area travels through this river. When rainfall is low, people can travel by car and cross the river with no problem. However, when rainfall is high, people must travel by foot to cross the river. The area around the Rio Nosara is so rich with flora and fauna that some locals want the Costa Rican government to declare it a national park.

	How about a kayak trip? It's both enjoyable and easy.
	Picture 3.1	As kayakers travel down the Rio Nosara towards the ocean, changes in plant life, animal life, and water clarity are quite obvious. Right before the river empties into the ocean, an estuary forms. This creates an environment where salt and freshwater mix, called brakish water.

 

Traveling up a stream, you can explore the area in and around the waterway.
