The best time visit Damascus is April, May, September, and October. At those times, the weather is ideal for exploring the city. Summer can be extremely hot with the average temperature during the day reaching 100 degrees.
I grew up near here. Riding the Creeper Trail is a truly bucketlist worthy experience. Spectacular scenery. I also recommend a visit during Trail Days. Truly a great trail town. Too bad Cowboys is closed now. Best fried chicken on the planet.
Once you get here you'll see the neverending greenery. There are some stone towers which are fairly popular, they look nice with the landscape and I think they have some meaning too.
