Cerro Tetakawi East Peak Trail

The Cerro Tetakawi East Peak Trail climbs the eastern summit of Cerro Tetakawi, the twin-peaked landmark rising above San Carlos in the Guaymas municipality of Sonora. The trailhead sits just off Federal Highway 15 / Boulevard Manlio Fabio Beltrones, reachable by car or taxi from central San Carlos in about ten minutes, with informal roadside space to park near the start of the path; no permit or entrance fee is required. From the trailhead, the route covers roughly 2.1 kilometers round trip and gains about 300 meters to the east summit, a compact but steep outing that typically takes 1.5 to 2 hours. The lower third follows a dirt path through desert scrub and thorn forest before tightening into a rocky, loose-surface scramble over exposed volcanic rock, with hand-over-hand movement required on the final approach; there is little to no shade anywhere on the climb. A series of cairned switchbacks leads to a natural rock notch that marks the last stretch before the summit; this notch is a sensible turn-around point for hikers uncomfortable with the exposed scrambling above it. From the top, views extend over the Sea of Cortez, Bahía San Carlos, and the marina below. There are no water sources, refuge huts, or shelter anywhere on the mountain, so hikers must carry everything they need for the full outing, and the loose volcanic rock becomes considerably more hazardous when wet.
