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.

Pro Tips
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.
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.
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.
