trilha

Trilha is a Portuguese noun with several related meanings centered on marked or visible routes. The most common sense designates a narrow path or route through natural or rural terrain, used for walking, hiking or trekking. Trilhas can vary in width, surface and level of difficulty and may be public, private, or part of a protected area.

A second sense refers to a planned route for exploration or recreation, such as a cycling trail (trilha de bicicleta), a walking circuit (trilha de observação de animais), or a network of paths promoted for tourism. In this use, trilhas are often signposted and mapped.

In Brazilian Portuguese, trilha is widely used in outdoor contexts and to describe bike trails, running routes, and exploratory paths. In Portugal, the term is understood and commonly encountered in everyday language, though caminho or senda may be used in some contexts. A related word, trilho, can mean a groove, a rail track or a line within a field, and is sometimes used interchangeably with trilha depending on region.

Trilha sonora is a phrase meaning soundtrack, notably for films, television, or video games; trilhas can also refer to multiple audio tracks in a recording, with faixa or faixa de áudio more common in some contexts.

Conservation and safety: Trails may pass through fragile ecosystems, so user responsibility—sticking to marked routes, avoiding disturbing wildlife, and packing out waste—is emphasized by park authorities and trail associations.
