Now through June 17th, every Saturday, the George W. Bush Presidential Center again offers its tremendously popular, docent-guided Bluebonnet Tours. Along with the stunning bluebonnets, the Native Texas Park on the grounds of the Bush Center features Blackland Prairie grases, other seasonal wildflowers, tree-shaded lawns, and clearings providing native habitats for butterflies, birds, and other species. This 15-acre urban park reflects the President and Mrs. Bush's longstanding commitment to environmental conservation and restoration. Weather permitting, these free tours are offered every Saturday at 10:00 am and 11:00 am, guide visitors through the one-mile network of walking trails. Space is limited and tours are available on a first-come, first-served basis.
