The Dr. Thomas Walker State Historic Site is located in Barbourville, Kentucky, and offers visitors a glimpse into the life of one of the early explorers of the American frontier. Dr. Thomas Walker, a physician and surveyor, was the first white man to explore the region beyond the Appalachian Mountains.

Visitors to the site can tour the recreated log cabin that serves as the visitor center and explore the grounds, which include a replica of a Native American settlement, a pioneer cemetery, and a recreated fort. The site also features hiking trails that take visitors through the surrounding woods and along the Cumberland River.

One of the highlights of the site is the Boone Trace, a historic trail that was blazed by Daniel Boone and his companions in 1775. The trail can be hiked today and provides a unique look at the rugged terrain that early pioneers had to navigate.

Interesting facts about the site include the fact that it was once the home of Abraham Lincoln's parents, who lived in the area before moving to Illinois. Additionally, the site is home to the largest osage orange tree in the state, which is estimated to be over 300 years old.

The best time of year to visit the Dr. Thomas Walker State Historic Site is in the spring or fall, when the weather is mild and the foliage is at its peak. However, the site is open year-round and offers a unique look at the history and natural beauty of the region.
