San Antonio travel tips

1) Be careful when walking along the Riverwalk in San Antonio

Riverwalk is a beautiful waterfront along the San Antonio River. However, be careful walking along the winding promenade – there are no fences, and about 500 people fall into the river every year.

2) Check out Tower Life Building in San Antonio

Tower Life Building is an architectural landmark of San Antonio. The 120-meter-high tower adorns the city and represents the neo-gothic style. The tower was built in 1927, and for 60 years, it used to be the tallest building in the city.

3) Spend a day outdoors at Brackenridge Park in San Antonio

Brackenridge Park is a large and well-kept park 5 km from the centre of San Antonio. There you can have a great time and ride the Brackenridge Eagle Miniature Train. It is a favourite vacation spot for locals and tourists alike, who are hiding here from the sweltering Texas heat.
