Alder Creek
What to Expect
Safety Advisory
The trail can be faint through meadow sections and unmarked at junctions — download offline maps or carry a paper topo. GPS breadcrumbs are your friend on this one.
Creek crossings can run fast and thigh-deep during peak snowmelt in May and June. Trekking poles and water shoes earn their weight on this trail.
Trail Details
- 1
Start from the Mosquito Creek Trailhead if you want the waterfall without the full 12-mile commitment — it cuts the route nearly in half and skips the least interesting section of forest road walking.
- 2
Carry at least three liters per person; there's seasonal water at creek crossings, but flow is unreliable by late July. A filter is essential if you plan to resupply from Alder Creek itself.
- 3
The falls photograph best in late morning when direct light hits the cascade face. Arrive by 10 AM and set up on the granite slabs at the base — they make a natural tripod platform and a decent lunch spot.
