Mill Creek Falls is the tallest waterfall in Lassen Volcanic National Park at about 75 feet, formed where East Sulphur Creek and Bumpass Creek meet. The trail starts near the Kohm Yah-mah-nee Visitor Center on the park's south side.
At 75 ft, it stands above roughly 57% of the 775 documented falls in this guide.
Mill Creek Falls sits on Mill Creek. You'll find it in Tehama, California. It is protected within National Park Service.
This is a moderate hike waterfall: a longer day hike, roughly one to several miles each way. Plan for a moderate hike; sturdy shoes, water, and a little time on the trail are worth bringing. The walk to the main viewpoint runs about 3.5 miles round trip. Base a visit out of Mineral, the closest town.
When to go: June to October. Like most waterfalls, Mill Creek Falls runs highest after snowmelt or heavy rain and can thin out in late summer, so it's worth checking recent streamflow and the land manager's conditions page before a long drive.
