Upper Midnight Hole

Big Creek is a clear, fast-moving stream that drains through the northern side of the Smokies near Waterville, North Carolina. Upper Midnight Hole sits about 1.5 miles up the Big Creek Trail, which follows a former railroad grade for most of its length — relatively flat, creek-adjacent, and easy to navigate. The falls drop roughly 6 feet over smooth bedrock and fan out into a broad pool that holds its color even on overcast days, the water staying visibly clear well into summer. It reads less as a vertical plunge and more as a cascade into a genuine swimming hole, which explains why this stretch of trail draws more foot traffic than its remote setting might suggest.

The creek comes down from elevation, and the pool temperature reflects that more than the ambient air does. Even on warm August afternoons, the water is cold.

Big Creek Trailhead is off Big Creek Road in Waterville, NC, and the approach feels different from the Gatlinburg-side trailheads: smaller lot, quieter, no commercial corridor on the way in. Upper Midnight Hole is 1.5 miles one-way on terrain rated easy to moderate. The grade is minimal for most of the route, following the old railroad bed, before getting rougher and rockier as you near the falls. Good footwear matters; the creek-adjacent sections stay wet underfoot regardless of recent rain.

Round trip runs about 3 miles with modest elevation gain — a comfortable two-hour outing for most people, assuming at least a brief stop at the falls.

People swim here, and the pool is genuinely deep enough to make it worthwhile. Before you get in: the water stays cold even well into summer because it drains from high elevation, the rocks around the base of the falls are slick even when they look dry, and depth at the pool entry shifts with seasonal flow. Current NPS guidance discourages jumping from above the ledge or climbing the rock faces adjacent to the falls. That guidance exists because slick rock and hidden currents are specifically how most waterfall-area injuries happen in the park — not generic liability boilerplate.

If you're swimming with kids, keep them on the shallow upstream edge of the pool and within arm's reach near the cascade itself.

The standard golden-hour advice doesn't apply here. Mid-day sun hits the water directly because Big Creek runs through a relatively open corridor at this section of the trail, and that direct light is what pulls the pool's color out. Early morning tends to leave the pool in shadow from the surrounding ridgeline.

For framing: position yourself on the near bank upstream from the pool edge to get both the drop and the pool in the same shot. A wide-angle lens works better than zoom compression at this scale. The water is clear enough that you'll get color in the pool on overcast days, though it reads flatter than in direct sun.

Big Creek keeps reliable flow year-round; Upper Midnight Hole doesn't thin out even in dry stretches of late summer, which isn't true of many smaller falls elsewhere in the park. Spring runoff pushes the volume considerably, the pool widens, and the cascade hits harder. Entry points shift with the higher water, so it's worth reading the pool before committing to getting in.

Winter access is a separate consideration. The rocks around the falls ice over when temperatures drop, and the trail gets slick well before the air temperature alone would suggest it. Traction devices are worth packing if you're visiting between December and February. Shoulder-season trips in late March or early November sidestep both the ice hazard and the summer crowds.

Big Creek Trailhead sits on the north side of Great Smoky Mountains National Park, most easily reached via I-40 East from Knoxville. Take exit 451 toward Waterville and Mount Sterling, then follow Big Creek Road about 2 miles into the park to the trailhead and campground. This approach bypasses Gatlinburg and Pigeon Forge entirely, which cuts meaningful time off the trip if you're coming from the Tennessee side and don't need to stop.

A Park It Forward parking tag is required for stays over 15 minutes anywhere inside the park. Daily tags cost $5, weekly $15, and annual $40; buy through recreation.gov or at park fee stations before you park. The trailhead has a small picnic area and restrooms. Cell coverage is unreliable at the lot and usually gone once you're on the trail.

Pack more water than a 3-mile outing seems to justify. Hiking in heat and stopping to swim push consumption higher than people expect, and there's no water source you'd want to drink from without treatment. A lightweight rain layer is worth carrying from May through September, when afternoon thunderstorms build fast and the north-facing terrain holds moisture longer than open ridgelines.

Black bears are active throughout the Big Creek area; encounters on this trail are common enough that the standard guidance deserves actual attention rather than a skim. Make noise while hiking, keep food sealed in your car or a bear canister, and give at least 50 yards of distance if you spot one.
