Join the Georgia Sierra Club Meet-Up site to get the latest updates on local activities, including hikes, meetings, and events.


Kennesaw Mountain Trail Hike - Saturday Jan 24th 2.5 miles - 700 feet elevation gain. Approx 2.5 hours. This is a popular trail area in Atlanta for people preparing to hike the Appalachian Trail, the National Parks or climbing mountains, but we will take a relaxed pace up Kennesaw Mountain, stopping along the way at several overlooks to discuss the history and construction of the trails. On the return, we will branch off to the Camp Brumby Loop Trail and visit the site of the Civilian Conservation Corps Camp Brumby, where 200 men lived when building the trails and preserving the park’s history. The CCC built 90% of the trails in the park, as well as many famous trails in Georgia and around the US. We will discuss current efforts by groups to help establish and maintain hiking trails in Georgia. Limit 10. Great opportunity to explore the historic national treasure in our backyard.

Vogel State Park Hike - Saturday, January 31, 8:00am to 4:00pm. (time tentative). A Moderate Winter Hike from Vogel State Park to Blood Mountain 2200 feet up via the Coosa Loop, Duncan Ridge Trail and Appalachian Trails. We will have lunch on top of Blood Mtn by (or in) the CCC Shelter. We will return to Vogel via (or in) the same trails, but take the parallel Bear Hair trail from the Coosa Loop trail with an short loop trail to the Lake Trahlyta overlook. Bring your gloves, warm hats, good boots and layers of clothing as we enjoy the woods in the winter. The trail is generally moderate except for a steep uphill in mile 2. We will take a moderate pace.
