I completed a 76 mile through hike of the the Foothills Trail. I started at Table Rock State Park and ended my hike in Oconee State Park.
I had rain for the first three days and good weather the last two.
The trail is in excellent condition and easy to navigate. The terrain is varied, but I would say at least half of it rises and descends in and out of gorges.
I would also say that if you are planning a thru hike of this trail, be prepared for the following:
1. There are some very strenuous sections, especially between Laurel Valley and White water falls. Be prepared for steep ascents and descents while negotiating wooden stairs carved into the hillsides. There are also many bridges, which make this trail a pleasure to hike. Be very careful of the bridges and stairs as they are very slippery in wet weather.
2. Carry everything you will need for the entire 76 miles. Even though this trail crosses hiways a few times, there are no stores. You may also consider caches at some of the many trailheads/road crossings along the way. I carried everything. I had about 8 lbs of food starting out and ended with about 1 lb of food at Oconee.
3. Be prepared for rain, and in summer, be prepared for some intense storms that are likely to hit quickly and leave you drenched.
4. Take the time to stop and listen occasionally. I am amazed at how often you can hear falling water along almost the entire trail.
5. I had a great hike, even though the weather was a little rough the first three days. Please check out my trip photos here:
