In rock climbing and ice climbing, a pitch is a steep section of a route that requires a rope between two belays, as part of a climbing system. Standard climbing ropes are between 50 and 80 metres long, so a pitch is always shorter, between two convenient ledges if possible; longer routes are multi-pitch, requiring the re-use of the rope each time. In free climbing, pitch refers to classification by climbers of the difficulty of ascent on certain climbing routes.

The Parque Nacional de las Cavernas del Río Camuy is a cave system in Puerto Rico. It is located between the municipalities of Camuy, Hatillo, and Lares in northwestern Puerto Rico, but the main entrance to the park is located in Quebrada, Camuy. The caverns are part of a large network of natural limestone caves and underground waterways carved out by the third-largest underground river in the world, the Río Camuy. The cave system was "discovered" in 1958 and was first documented in the 1973 book Discovery At The Río Camuy (ISBN 0-517-50594-0) by Russell and Jeanne Gurnee, but there is archaeological evidence that these caves were explored hundreds of years ago by the Taíno Indians, Puerto Rico's first inhabitants. Over 10 miles of caverns, 220 caves and 17 entrances to the Camuy cave system have been mapped so far. This, however, is only a fraction of the entire system which many experts believe still holds another 800 caves. Only a small part of the complex is open to the public. The 268-acre park built around the cave system features tours of some of the caves and sinkholes, and is one of the most popular natural attractions in Puerto Rico. As of January 2019, the park is still closed for Hurricane Maria recovery.
