When you break a sweat picking the newspaper from the front yard at 7 a.m., it’s time to visit Foster Falls, a 60-foot waterfall in Marion County, Tennessee, about 40 miles northwest of Chattanooga. That’s exactly what I did today, in the company of four friends, who, like me, craved the sweet relief of something cold. We panted and sweated down a boulder-strewn trail to the edge of a large pool — and gazed skyward to behold… a tiny trickle of water, splattering down from the top of a sandstone cliff. Ok, so the drought has not been kind to Foster Falls. But that didn’t make the water at the bottom any less refreshing. Foster Falls is in the Tennessee Valley Authority Natural Area and is the ending point of the 12.5-mile Fiery Gizzard Trail, known for its exceptional views, spring wildflowers and winter ice formations. The cliffs along the trails in the Foster Falls area draw rock climbers from all over who like sport climbing and the challenge of overhangs. This afternoon, we treaded water in the deep part of the pool and watched, sometimes cringingly, as climbers ascended the rock face behind the waterfall and released, kawoosh, hitting the water. Around the banks of the pool, some sunned on the rocks and others threw sticks for their dogs to fetch. After a while, we wrapped ourselves in beach towels and climbed the trail back to the parking lot. We hit the Dairy Queen in Jasper about 15 minutes down the road back to Chattanooga, just in time to buy an ice cream Blizzard before we dried off completely.
