Features Birding · Fall Colors · River/Creek · Spring · Swimming · Views · Waterfall · Wildflowers · Wildlife

Family Friendly Many campgrounds and swimming holes are available along this route for fun in the sun. Be advised that older kids will enjoy the adventure, but it might be too much for younger tots.


Follow along the Fiery Gizzard Creek, chasing waterfalls, experiencing stunning overlooks, and working your way through old growth forests.

Need to Know

Please note that this route isn't an out an back, and you'll either want to arrange to leave a car at each end of the trail or plan to camp along the way.


Beginning at the Foster Falls parking lot, witness the 60 foot waterfall at the start. From the overlook, go to the right and cross the bridge to start the trail. Continue on the Fiery Gizzard Trail as it leads you deep into the old growth forest, coming across many creeks that fall off the rock ledges that dot the landscape. Don't worry, there are bridge crossings for each creek, and the views atop the waterfalls are stunning.

After traveling 2.5 miles, you'll come across a backcountry campsite. From there, you'll descend into a gorge and climb back up on the other side along the strenuous trail. You'll continue deep into the lush forest before coming into the Grundy forest. You can stop at Ravens Point, 5 miles to the Grundy Day Loop parking lot, for an unbelievable view.

Advance onto Sycamore Falls and where you'll find a few more stunning waterfalls, cascading streams and swimming holes. There's a slight incline on the way back towards the parking lot of the Grundy Forest.

Flora & Fauna

Old growth forests shade your journey.

Awesome trail. Beautiful waterfalls. Did not have time to do the 4 mile portion of the trail with the very difficult rock garden due to nightfall
