What makes Alkali Falls special
Alkali Falls is a multi-step waterfall of six tiers on the east side of the Rogue–Umpqua Divide Wilderness in Douglas County, Oregon, just west of Mount Bailey and Diamond Lake on Oregon Route 230. The description puts the total fall at 510 feet in six drops, which makes it one of the tallest cascades in Oregon.
The biggest single step is the Upper Alkali, the tallest drop at 130 feet. The rest of the fall steps down below it in five more drops, so the water keeps falling in stages rather than in one plunge. It is the stepped form that makes the total so large: no single drop dominates, and the whole 510 feet is the sum of the six.
Its nearest neighbours are National Falls 2.8 miles away, Rough Rider Falls 4.1 miles away and Deer Lick Falls 11.6 miles away, so the Rogue–Umpqua Divide country holds several falls within a short drive of each other.

Geology and background
Alkali Falls is a tiered fall: six drops stepping down the east side of the Rogue–Umpqua Divide. The tiered form is what makes the total height so large while no single drop dominates. The tallest step, the Upper Alkali at 130 feet, leads the fall, and the water drops in five more stages below it.

Getting there and parking
- GPS: 43.0685, -122.3672 — Get directions
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: this is wilderness country, and signal is not guaranteed.
Best time and crowds
No stream gauge is linked to Alkali Falls, so recent rain is your best guide. Expect the most water in spring and after heavy rain. In a dry spell, especially late summer and early fall, the same fall can look half the size.
This is a wilderness fall on the edge of the Rogue–Umpqua Divide, not a roadside stop, so it stays quieter than the famous falls. Even so, an early start is the best way to have the viewpoint to yourself.
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. A six-tier fall means the rock is wet for a long way down: keep your distance from the whole slope, not just the top.
What to bring
- Shoes with real grip
- A rain shell for the spray
- Water and a snack
- An offline map or screenshot
- A dry bag for your phone
- A bag to pack out trash
Practical tips
- Look for all six tiers: the 510-foot total is the sum of the drops, with the Upper Alkali the tallest at 130 feet.
- Go in spring or after rain, when the fall is running full.
- Screenshot the directions and these coordinates before you leave town: signal is thin out here.
- Pair it with National Falls, 2.8 miles away.
