Unplug Texas Day at Guadalupe River State Park is a day to put your phone down and get outside. Held at the park in Spring Branch, just outside San Antonio, it's all about reconnecting with nature, family and friends. Wander the park's trails, go birdwatching, join a nature scavenger hunt and try other outdoor activities. Guadalupe River State Park is a lovely spot for a day under the Texas sky, with the Guadalupe River winding through the hill country.
