Waterfall Hikes of South Cumberland State Park: Foster Falls and Denny Cove

If you’d have asked me two years ago, I’d have said that this journey wasn’t sustainable, and that I’d eventually run out of new trails reasonably close to home. Two years later, I still feel like I’ve barely scratched the surface. I travel as often as I can, and since I began this journey, almost half of my new hikes have occurred on trails outside of Tennessee. As much as I’ve loved the trails of amazing destinations like Maine, Colorado, Utah, and California… there’s no place like home. I appreciate the breathtaking beauty of expansive mountain views, but there’s something so intimate and comfortable about the hidden waterfalls and majestic limestone bluffs of the Cumberland Plateau. If you’re looking for views that extend far and wide, Tennessee may not be for you, but if you’re looking for pristine beauty that’s buried and unpretentious, come on in. The water’s fine. And so are the caves.

The icicles surrounding Foster Falls may be too small to notice in this photo, but the views of this area in January were a rare and magnificent treat when I hiked here.

Tennessee offers no shortage of incredible waterfall hikes, and nothing influences the kind of experience you’ll have on one of these trails more than timing. I’d love to tell y’all that any time is a good time for a waterfall hike in Tennessee, but I’ve learned from experience that this isn’t necessarily true. The magic of seasonality can make one hike feel like four unique experiences, and I wholeheartedly appreciate that. Hiking to Foster Falls and Denny Cove in January reminded me so much of how my journey began two years ago, with my winter hike to Virgin Falls. If you’ve got the layers for it, I highly recommend a Tennessee waterfall hike in January. We don’t get much snow in winter in this part of the country, but temperatures fall (and stay) below freezing often enough to create magnificent icicle formations on our waterfalls. With all of this in mind, a sunny January day with sub-freezing temperatures may not be an ideal day for hiking for most people, but fortune favors the bold… or the cold, in this case.

As an added bonus, Tennessee’s popular trails don’t receive much foot traffic in January. Most of the visitors to South Cumberland State Park drive in from other parts of Tennessee, and winters in the volunteer state just aren’t consistent enough for our Southern blood to properly acclimatize. It’s a mystery to me though, because winter can still be beautiful without the presence of snow-capped peaks and frozen lakes. Snow flurries against a waterfall backdrop and high cliffs draped with thousands of sparkling icicles decorate the Cumberland Plateau in winter, and the trails (usually) remain clear of ice and other winter obstacles. It’s rare to experience conditions that offer the best of both worlds, but when the opportunity presents itself, why not take advantage of it?

It was 20 degrees with a forecast of clouds and sporadic snow snow flurries when I started my morning at the Foster Falls trailhead, named for the landmark feature at the eastern terminus of Fiery Gizzard. I hiked a western portion of Fiery Gizzard, one of Tennessee’s most alluring and popular trails, in October of 2018, and a through hiker I met on the trail told me about the idyllic brilliance of Foster Falls. I’ve wanted to visit ever since, and I’m so grateful that I had the opportunity to witness this beautiful place for the first time without anyone else around. I’ve heard that visitors flock to this waterfall in the summer months, because of the gorgeous and spacious swimming hole at the bottom of the falls. The hike to Foster Falls is relatively short and easy as well. I hiked a loop trail that runs two total miles, starting with a steep descent from the top of the falls to the swimming hole and spacious creekside areas at the bottom. From the base of the falls, the trail follows a moderate incline along the base of one of Tennessee’s most popular rock climbing walls, which was dripping with icicles and thus understandably vacant in January.

After ascending to the rim of the canyon that Foster Falls flows into, the trail continues along the edge and provides an outstanding glimpse of the waterfall from above before returning to the trailhead. Overall, the this loop offers many gorgeous views for a relatively easy hike. There’s also the option to continue hiking along the rim of the canyon on the Fiery Gizzard Trail, which extends for 12 miles in one direction before meeting its western terminus at the Grundy trailhead.

I’d be lying if I said it’s worth the effort to drive two hours one way for a two mile hike in January, although I thoroughly enjoyed the beautiful scenery at Foster Falls. South Cumberland State Park’s newest addition, however, is accessible from a trailhead only ten minutes down the road from Foster Falls. Denny Cove offers about four total miles of trails. It doesn’t sound like much, but this trail packs in a lot of value over a relatively short and moderate distance. A vast and beautiful cliff runs parallel to the trail on the north side, and this area is accessible to rock climbers during warmer months. In winter, however, the tree cover between the trail and the cliffs is sparse enough to provide extensive views of this gorgeous landscape. Overall, the terrain is mild but not entirely easy, and the trail ends at a glorious waterfall that isn’t visible until you’re right beside it. As the trail ascends, it inches closer to the creek that runs through the cove. As the trail approaches the waterfall, the incline increases before leading to a small open space with unobstructed views of Denny Cove Falls.

On the return trip from Denny Cove Waterfall, I hiked the spur trail to and from a secluded overlook off the main trail. This route extends the 3-mile roundtrip hike to the falls by a mile, but the views are worth the short detour. It’s worth noting that, for the first time since I started this journey two years ago, I was entirely and blissfully alone on this previously unexplored trail. I saw a few people on the Foster Falls loop, but I didn’t see anyone on my hike through Denny Cove. This surprised me, even though the trail is relatively new and the weather was brutally cold (for Tennessee, anyways). Most people avoid hiking on days like this, but I eagerly anticipate them and hope they land on weekends when I can actually get outside to enjoy the solitude of a sub-freezing hike.

This overlook along the trail to Denny Cove Falls offers stunning views of the valley below.

It takes more than just cold weather to make a hike like this possible. Cliffs and waterfalls need rain and the resulting runoff to sprout icicles, and then the sun needs to shine for a day or two to reduce ice and slushy mud enough to make the trails navigable. The sunny days need to be bright enough to warm the ground, but the temperatures need to be low enough to keep the ice on the cliff walls from melting. Rock surfaces warm more slowly than dirt, so it takes nothing short of an act of God to create the perfect conditions for a waterfall hike adorned with icicles. It doesn’t happen often around here, but when it does, the rare opportunity to see a sight like this in Tennessee is certainly worth the extra layers.
