A growing body of scientific literature emphasizes the role of the built environment in shaping commuting behavior among adolescents. However, the comparison of the built environment on adolescents&rsquo: route choice remains underexplored. A total of 317 Spanish adolescents participated in the study, of whom 67 adolescents provided a valid GPS-identified walking route between home and school (54.5% girls: mean age = 14.4 ±: 0.7 years). Built environment variables&mdash:including residential density, number of intersections, land use mix, number of services, number of visible services from the route, street width, walkability, park area, elevation gain, elevation loss, and topographic cost&mdash:were measured using 3.28.8 QGIS software. A paired-sample analysis was performed using the Wilcoxon signed-rank test and the sign test to compare the actual route with the shortest available route. The results showed a deviation of 63.96%. Comparisons between the actual routes and the shortest ones revealed a statistically significant difference in the number of intersections (p = 0.009) and topography cost (p = 0.050). Likewise, a significant trend was found with the residential density (p = 0.080). These findings suggest that in this case study, the built environment plays an important role in adolescents&rsquo: decision-making when choosing routes for commuting to school. Some urban planning and design recommendations were given to address the results from a school built-environment-oriented approach.
