Appalachian Trail favorite
At 4458 feet elevation, Blood Mountain is the highest peak on the Georgia section of the Appalachian Trail (AT). This is my favorite hike in the area and at 4.4 mi RT combines a good work out with nice views (humidity permitting).
Blood Mountain gets its name either from a bloody battle between the Cherokee and Creek Indians in the 1600's or perhaps from the red lichen that light up the trail. It sounds more exciting to think of bloodshed on the mountain, but no one really knows for sure. The trailhead I've always used to go up Blood Mountain is directly across from the Walasi-Yi Interpretive Center parking lot at Neel's Gap. But it's tricky to park downhill on the edge of the steep road and can be dangerous with weekend traffic to walk back up to the TH.
Now people prefer to use the Byron Herbert Reece Access Trail (formerly known as Blood Mountain Spur) which is 0.5 miles North downhill past the Walasi-Yi Interpretive Center. This access trail is 0.7 miles long and dead ends into the AT (1.0 miles to the left to Neel's Gap and 1.5 miles to the right to the summit). The remaining 1.5 miles on the AT to the summit are mild switchbacks with a steady climb and no views until you get to rock outcrops just below the summit.
Once at the summit, look for the shabby but historic shelter built in 1934 by the Civilian Corp of Engineers. This trail is very busy on Spring, Summer, and Fall weekends with all the Atlanta day hikers.
There are many options to lengthen this hike with loops or combine it with other features in the area. My top two (day trip length) combinations are: Blood Mtn/DeSoto Falls or Blood Mtn/Lake Winfield Scott. A fun, non-camping base station for a visit would be in Dahlonega, GA which embraces its history as the first gold-rush city in the US reflected in its kitschy shops and B&B's.
WARNING! Hiking and outdoor related sports can be dangerous. Be responsible and prepare for the trip. Study the area you are entering and plan accordingly. Dress for the current and unexpected weather changes. Take plenty of water. Never go alone. Make an itinerary with your plan(s), route(s), destination(s) and expected return time.
