The Big Tree (Williamson Bur Oak)
Bur Oak (Quercus macrocarpa). 350 to 400 years. Free. Stands on privately owned farmland (the Williamson family, six generations) but is publicly accessible right beside Bur Oak Road, and the Katy Trail State Park rail-trail runs just yards away, making it a well known stop for cyclists. No fee found.
