The Ruta Panorámica (Scenic Route), officially the Ruta Panorámica Luis Muñoz Marin (Luis Muñoz Marin Scenic Route), is a 167-mile (269 km) network of some 40 secondary roads which traverse the island of Puerto Rico from west to east along its Cordillera Central (Central Mountain Range). Most of the route consists of three roads, PR-105, PR-143, and PR-182. The route starts in Mayagüez and ends in Maunabo. The first major segment of the route runs from Mayagüez to Maricao as Route 105, then from Adjuntas to Aibonito as Route 143, and then follows Route 182 toward Maunabo.
Early in the 1970s, the Autoridad de Carreteras de Puerto Rico (Puerto Rico Roads Authority) developed a 220-kilometer route along the Cordillera Central. The route was finished in 1974. According to the original plans, the route started at Cerro Las Mesas in Mayagüez, ran along the full length of the central mountains, including along parts of the length of the Sierra de Cayey to end at Cuchilla de Pandura, in Yabucoa. The development of the route included the building of overlooks, rest areas, and recreational facilities at a cost of $4 million. In 1975, it was estimated that the cost of the necessary facilities to complete the Route - but excluding roads already built - amounted to $20 million. National Geographic has called the route "an assemblage of 40-plus roads that cuts through the island's lush Cordillera Central." 
As the Route is a two-way road, it can be traveled starting at either its western or its eastern terminii. To travel the Route in a westerly direction (i.e., from Maunabo to Mayagüez), the course of the road is reversed from what is given here. Starting from Mayagüez and ending in Maunabo, as of August 2010, the course of the Route is as follows:
