The Guaymas area has plenty of rugged topography worth exploring, but the downtown streets are grimy and dilapidated. Most foreigners stay in San Carlos, which is like a distant suburb of Guaymas full of resorts (and more beautiful nature). A well-built 6'+ Mexican crazy guy pushed me on the sidewalk in broad daylight in downtown Guaymas after I ignored his request for money, then slapped me in the face with his T-shirt when I turned to confront him. He failed to knock the hat off my head. I continued walking and yelled insults from a safe distance, deciding not to start a brawl over his provocations. Shortly after I changed my mind and turned around to look for him, but he had disappeared and I never saw him in the streets again.
