A "circuitous way" describes a route that takes an indirect or roundabout path, often resulting in a lengthier trip. Some synonyms for this phrase include "labyrinthine," "meandering," "roundabout," "serpentine," and "tortuous." "Labyrinthine" refers to a confusing or complex series of paths, while "meandering" describes a route that follows a winding path. "Roundabout" is a more straightforward synonym that simply means taking a longer route to reach a destination. "Serpentine" specifically refers to a route that twists and turns like a snake, while "tortuous" suggests a difficult and convoluted path. All of these words can be used interchangeably with "circuitous way" to describe a longer, more winding route.
