Tanalian Falls drops about 30 feet over an ancient lava cliff on the Tanalian River near Port Alsworth, reached by a forested trail in Lake Clark National Park. The route passes birch and spruce groves with views of Lake Clark before the falls.
Its 30 ft drop is taller than about 24% of the 775 waterfalls we track.
Its water comes from Tanalian River. It lies in Lake and Peninsula, Alaska. The site is on public land managed by Lake Clark National Park & Preserve (NPS).
This is a moderate hike waterfall: a longer day hike, roughly one to several miles each way. Reaching it takes a moderate walk, so budget time and pack water before you set out. The walk to the main viewpoint runs about 4.4 miles round trip. The nearest town is Port Alsworth.
When to go: Summer (Jun-Sep). Flow usually peaks after snowmelt and heavy rain and tapers through late summer — a quick look at recent streamflow and the managing agency's conditions page can save a wasted trip.
