National Route 18 (Costa Rica)

National Route 18 is a primary road in Costa Rica. It runs along the Pacific coastline in the northern part of the country, within the province of Guanacaste. The route is often referred to as the "Ruta Costanera" or "Coastal Route" because of its proximity to the ocean.

The highway generally follows a north-south trajectory, connecting various coastal towns and communities. Significant locations along its path include, but are not limited to, the area of the Tempisque Bridge (Puente de la Amistad), which provides a crucial link across the Tempisque River, and various access points to popular beaches and tourist destinations within Guanacaste.

The condition of National Route 18 can vary along its length. While some sections are well-paved and maintained, other segments may experience potholes or require improvements. Travelers should exercise caution and check current road conditions, especially during the rainy season when flooding or landslides can occur.

National Route 18 is an important artery for tourism, commerce, and local transportation in the Guanacaste region. It provides access to numerous hotels, resorts, and ecotourism destinations, and facilitates the movement of goods and people between communities. The route also serves as an alternative to the more inland National Route 1 (Pan-American Highway), particularly for those seeking coastal access and scenic views.
