SAN AUGUSTINE

With more than 114,000 surface acres, Sam Rayburn is the largest man-made lake that is completely within the boundaries of the state of Texas. The reservoir is fed by the Angelina River, a major tributary of the Neches River. The piney woods region boasts native flora like orchids, insect-eating plants and scores of animal species.

Recreation: The lake is a highly popular destination for boating and fishing. Game fish include largemouth bass, bluegill and channel catfish, but it is the abundance of bass, which inspires more than 500 annual tournaments.

Nearby: From the eastern edge of the lake, hikers can embark on a 28-mile trail that heads east to the Toledo Bend Reservoir.
