San Diego travel tips
Head to the San Diego Museum of Us, which is housed in four beautiful Spanish colonial-style buildings. Here you will learn about pre-Columbian American history, Native American culture, and Mesoamerican civilizations such as the Maya. One exhibit deserves special attention — a massive golden beer goblet that belonged to the Inca king about 600 years ago. The admission is just $20.
Watch out for prohibition signs in San Diego. You can smoke there only in specially designated places. For smoking other than at designated smoking points, the police can hand you out a fine of up to $250 (for example, for smoking in a hotel).
San Diego boasts an abundance of sunny days a year and beautiful beaches with water temperatures higher than in other parts of California. Great swimming is guaranteed here from July to October. Summers are usually dry and hot, while winters are mild and short. Even in the coldest months, the air temperature does not drop below +15 degrees Celsius.
