My fiance and I are going to Ensenada for a weekend in July with another couple. We investigated a beach house rental but they are either too expensive or not available. So we are probably going to stay at the Posado El Rey Sol Best Value Inn in downtown Ensenanda. We would like to go to the beach south of Ensenada while there though at Punta Banda. Are the beaches there public? Is there anywhere to change clothes?
