What to Do
San Antonio is a blend of its unique heritage through a mix of Native American, Spanish and the Wild West. There is not a huge amount of time to explore but here are some places you might want to visit for some art and culture.
The Alamo // Downtown

The McNay Art Museum // Alamo Heights
Spanish Colonial Revival home turned gorgeous museum and grounds. It is a 10 minute Taxi but worthwhile. A good time to visit would be before or after the Poolside Lunch on Friday as it is in the same neighborhood–Alamo Heights.

Blue Star // Southtown
Drink beer, explore the art, rent bikes and tour the San Antonio river and surrounding area.

Mission San Jose // Missions National Historical Park
The closest Mission to downtown, Mission San Jose was built by the Spaniards in 1720. Sunday mass is still held, but you can visit anytime to tour the beautiful grounds.
