How many waterfalls are in Yellowstone?
More than 290 named waterfalls have been documented in Yellowstone, and the real total is higher because new ones are still being found in the backcountry. The number comes from survey work done through the 1990s, when researchers systematically walked the park’s drainages and catalogued what had never been formally recorded. Before that the accepted figure was around 40.
The counting rule matters. The 290 figure covers named, mapped drops of roughly 15 feet or more on a permanent watercourse. Count every seasonal cascade and snowmelt drop and the number runs far higher. Of the 290, only about a dozen are reachable on a maintained trail, which is what the rest of this guide covers.
The biggest is the Lower Falls of the Yellowstone at 308 feet, almost twice the height of Niagara. The tallest in the park is Silver Cord Cascade at roughly 1,200 feet, a thin ribbon on the far wall of the Grand Canyon of the Yellowstone that most visitors never notice.
Yellowstone is famous for geysers, but the park also holds more than 290 waterfalls, and a handful of them sit at the end of genuinely great hikes. The thundering 308-foot Lower Falls is twice the height of Niagara, and several lesser-known cascades let you escape the boardwalk crowds entirely. Here are the waterfall hikes worth planning a day around, with practical trailhead details for each.
Lower Falls and the Grand Canyon of the Yellowstone
The Grand Canyon of the Yellowstone is the park's most dramatic landscape, and the trails along its rim deliver the best waterfall views anywhere in the region. For the classic head-on look at Lower Falls, hike Uncle Tom's Trail down 328 metal steps on the South Rim, or walk the short paved path to Artist Point. On the North Rim, the steep Brink of the Lower Falls Trail drops about 600 feet in half a mile to put you right at the lip of the cascade. Go early, because both rim parking lots fill before 9 a.m. all summer.
Fairy Falls
The Fairy Falls trail is a 5.4-mile round trip from the Fairy Falls Trailhead just south of Midway Geyser Basin. The flat, easy path leads to a delicate 200-foot ribbon of water dropping into a forested basin. The bonus here is the short spur near the start that climbs to the overlook above Grand Prismatic Spring, where you get the famous aerial view of the rainbow-colored hot spring. Combining the two is one of the best half-days in the park.
Mystic Falls
Tucked behind the Biscuit Basin boardwalk, the Mystic Falls hike is a 2.4-mile loop to a 70-foot falls on the Little Firehole River. Continue up the switchbacks for an overlook with a panorama back over Old Faithful and the Upper Geyser Basin. Note that Biscuit Basin has had closures from hydrothermal activity, so check the park's current alerts before you go.
Tower Fall
In the park's quieter northeast, Tower Fall drops 132 feet through eroded volcanic pinnacles. The overlook is a flat five-minute walk from the parking area near Tower Junction, making it the easiest waterfall stop in Yellowstone and a good one to pair with wildlife watching in the Lamar Valley.
What to Pack and When to Go
Yellowstone's waterfalls run highest in late May and June when snowmelt swells the rivers, though many high trails are still muddy or snowbound then. July through September offers the most reliable trail conditions. A few essentials for any waterfall hike here:
- Bear spray on every trail, no exceptions. Yellowstone has one of the densest grizzly populations in the lower 48.
- Sturdy shoes for slick, misty steps near the canyon falls.
- An early start, since canyon parking lots and the Fairy Falls lot fill fast.
- A reusable water bottle and sun protection at elevation around 7,800 feet.
Fit These Falls Into a Two-Park Road Trip
Most of these waterfalls cluster near the central Grand Loop, which makes them easy to string together over a few days. Our 7-day Yellowstone and Grand Teton road trip itinerary sequences the canyon falls, Fairy Falls, and Grand Prismatic alongside Old Faithful and the Teton Range so you cover both parks without driving in circles. It is the cleanest way to see Yellowstone's best water and geothermal features in one week.

The Grand Canyon of the Yellowstone offers the best waterfall hiking. The Brink of the Lower Falls Trail and Uncle Tom's Trail both put you right against the 308-foot Lower Falls, the tallest in the park.
No, the Fairy Falls trail is a flat, easy 5.4-mile round trip. The short spur to the Grand Prismatic Spring overlook adds a brief uphill but is well worth it for the aerial view.
Waterfalls peak in late May and June during snowmelt. However, many high trails are still snowbound then, so July through September offers the best balance of flow and dry, accessible trails.
