Effort (1-9) is computed from distance, ascent and terrain; technical (A-E) follows the trail class, from a clear path (A) to real climbing (E). Elevations, grades and trail data are indicative - always verify with the LGU / DENR before a climb. Routes come from OpenStreetMap and can be partial or outdated; a mapped line does not prove a safe or open path.
