My wife and I try to go hiking at least a couple of times a month and used one of our vacation days to explore the Sweetwater State Park yesterday. We checked a book out of the library entitled "60 Hikes Within 60 Miles of Atlanta" and have used it as a guide. The book recommends doing a double loop at Sweetwater and we decided that we would start off with the yellow loop and continue down the red to the white loop to complete the circuit. We got over the plan for the double loop after dragging ourselves up and down the steep hills of the yellow loop. I would definitely recommend trying it out, but make sure you realize that you're going to be winded and probably worn out enough that the three mile loop will satisfy your hiking needs for the day. The trail starts off easy enough with a jaunt through the woods, but shortly after crossing the river you begin a quick, steep ascent up the ridge beside the river and when you think you've gotten to the top you come around a curve and realize there is another steep ascent. This happens at least three or four times and it does get a little disconcerting....and you may be thinking that you could start the loop from the opposite direction and avoid the climb, but its just as steep that way if not even worse. Of course, please do not take my word on it....go try it yourself!! You may find that it really is the challenging type of hike that you're looking for and love every second of it. My wife and I will be going out to the park again sometime hopefully sooner than later to check out the red, blue, and white trails, but I think I'll save the yellow for a while until I'm psyched up for the climb again. ...read more
