Tendoy Falls sits inside Yellowstone National Park, so the walk in comes with the park around it: marked trails, signed junctions and, usually, other things worth a stop on the same day.
What brings people back to Tendoy Falls is how different it looks from one visit to the next. A wet spring week and a dry August afternoon can feel like two different places.
Geology and background
What makes Tendoy Falls special
Tendoy Falls is one of the tightest-cluster falls in Yellowstone National Park. Gwinna Falls is 0.2 miles away, Sluiceway Falls 0.4 miles away and Wahhi Falls 0.6 miles away. Four named falls sit within a short walk of each other, so Tendoy Falls is one stop on a short run rather than a destination on its own.
The park setting does the rest. Yellowstone is geyser and river country as much as waterfall country, and the falls here sit in that wide, open ground. A single outing in this corner of the park can take in several falls without much driving between them.
Navigate by coordinates rather than by name. Map apps often send waterfall searches to the wrong parking lot or the far side of the stream. Download an offline map before you lose signal.
Prices and passes
Entry fee: $35.
Best time and crowds
No stream gauge is linked to Tendoy Falls, so recent rain is your best guide. Expect the most water in spring and after heavy rain, and in the snowmelt season. In a dry spell, especially late summer and early fall, the same fall can look half the size.
Yellowstone is busiest in summer. Arrive early or late: the middle of a summer day is peak time, and the park’s parking lots can be full by late morning.
Safety
Stay on marked trails and behind railings. Wet, mossy rock near the brink is the most common cause of serious injury. Never climb the cascade or stand at the top edge, even when the flow looks gentle. Plunge pools hide cold water, strong currents and submerged logs.

Practical tips
Walk the short run: Gwinna Falls is 0.2 miles away and Sluiceway Falls 0.4 miles away.
Screenshot the directions and these coordinates before you leave town.
Wear shoes you do not mind getting wet: spray reaches further than you expect.
Check the Yellowstone National Park page on the day for closures and entry requirements.
Waterfalls mark a change in the ground beneath a stream: a fault, a glacier-cut valley wall, or a band of hard rock the water cannot wear down as quickly as what lies below it.
Water flow and seasons
No stream gauge is linked to Tendoy Falls yet, so recent rain is your best guide. The weather panel on this page adds up the last three days of rain at the fall.
Flow tends to peak in spring with snowmelt and seasonal rain, and again for a day or two after a big storm. By late summer smaller falls can drop to a thin ribbon.
The trail and the viewpoint
We do not have a trail length for Tendoy Falls yet. Some falls are a few steps from a parking area, others take a real hike, so check the park or a trail app before you set out.
Swimming is not listed. Treat the plunge pool as off-limits unless signs say otherwise: the water at the base is colder and stronger than it looks.
Facilities and amenities
Facilities depend on Yellowstone National Park: larger parks usually have a signed trailhead, restrooms and a parking area, while smaller reserves may have none of these.
Plan as if there is no drinking water and no phone signal at the falls themselves. Use the restroom and fill your bottles before you start walking.
Fees, permits, and opening hours
An entry fee of $35.00 is listed. Fees change, and some parks charge per vehicle rather than per person, so confirm before you go.
Most falls are reachable from dawn to dusk. Gates, seasonal road closures and timed-entry permits are the usual surprises, so check the managing agency on the day.
How to get to Tendoy Falls
Tendoy Falls is in Yellowstone National Park, Wyoming. For the last stretch, navigate by coordinates (44.2842, -110.8787) rather than by name. Map apps often send waterfall searches to the wrong parking lot or the far side of the stream.
The final approach is usually the hardest part: narrow roads, small trailhead lots that fill early, and a walk that can be ten minutes or several hours. Download an offline map before you lose signal.
Our Wyoming waterfalls page maps every fall in the state, which helps when you are planning a route.
For the fullest flow, visit Tendoy Falls in spring or within a couple of days of heavy rain. For easier footing and warmer air, early summer is the compromise.
Light matters for photos: the base of a fall is often in shade by midday, and an overcast day evens out the bright water against dark rock.
Crowds and timing
Weekday mornings are the quietest. On summer weekends, popular falls can fill their parking by mid-morning, and the viewpoint becomes a queue.
Holiday weekends and the first warm days of spring are the busiest of all. If the lot is full, do not park on the road shoulder: it is the most common reason for tickets and towing at trailheads.
How long to spend there
Without a listed trail length, plan for half a day: enough time to find the trailhead, walk in, spend an hour at the water and walk out without rushing.
If there are other falls nearby, they are often on the same road or trail system. Two or three in a day is very doable.
