Alpental Falls is a seasonal waterfall which flows off the flank of Snoqualmie Mountain, north of Snoqualmie Pass. The falls skip about 250 feet down to the headwaters of the South Fork Snoqualmie River, next to the parking area for the Snow Lake trailhead and the Alpental Ski Area. Several other seasonal waterfalls can be seen adjacent to Alpental Falls, all of which have smaller drainage areas and usually run dry earlier in the year. Due to the drainage size, the falls usually run dry by the end of July.
