Spring is a great time to see the incredible diversity of wildflowers on Panola Mountain. Not your typical habitat, this 100-acre granitic rock is a tough place to grow! See the beautiful Red-leaved Diamorpha, the delicate Sandwort, and the rare Granite Stonecrop. Register in advance. Meet at the Park’s Interpretive Center. $7 plus $5 parking. 770-389-7801.
