Spend a spring day along the River Walk, biking, strolling, kayaking, or canoeing. May weather in the mid-80s is ideal for visiting the San Antonio Zoo and Natural Bridge Wildlife Ranch as well as exploring the Natural Bridge Caverns for a tour of underground natural formations formed over millions of years. Families will also enjoy the entertainment and rides at Six Flags Fiesta Texas and Seaworld. Return to the 15-mile waterway in the evening for dinner, shopping, and a stay at Thompson San Antonio - Riverwalk for their spa, cocktails, pool, or all-day Landrace, helmed by James Beard Award finalist chef Steve McHugh.
