Sonora is a vast desert state in northwestern Mexico bordering Arizona, spanning the Sonoran Desert from the Sea of Cortez coastline to the Sierra Madre Occidental foothills. Its capital, Hermosillo, sits at the base of Cerro de la Campana, while the coast delivers the resort towns of San Carlos and Puerto Peñasco (Rocky Point), the historic port of Guaymas, and the UNESCO-listed volcanic dunes of El Pinacate y Gran Desierto de Altar. Inland, the restored silver-mining Pueblo Mágico of Álamos preserves one of Mexico's best-kept colonial cores, far from the standard tourist circuit.
Top trails
Routes worth lacing up your boots for.
Trail difficulty levels
Pick a route that matches your fitness and experience.
Flat or gently rolling paths under 3 km, such as the Parque La Sauceda nature trails or the Cerro de la Campana walk, suited to walkers of any fitness level with no scrambling required.
Trails with a few hundred metres of elevation gain, such as the Cerro Tetakawi peak trails or the La Colorada Park circular route, requiring reasonable fitness and sturdy footwear.
Long, sustained climbs or remote desert routes far from services, such as the La Colorada Park to Pico Negro traverse or the El Elegante Crater approach across El Pinacate's gravel roads, requiring good fitness, extra water, and often a high-clearance vehicle or local guide.
