San Diego travel tips
Do you want to see the 600-year-old Inca Goblet in San Diego?
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.
