Mill Creek flows out of the Southern end of the Lassen Volcanic National Park, several miles North from the Southern Entrance to the Park lies the Mill Creek Falls trailhead. The Mill Creek Falls Trailhead takes off behind the Kohm Yah-mah-nee Visitor Center, at the site of the old Lassen Park Ski Chalet.
The trail is a moderate 3.8 mile round trip takes 2 – 2.5 hours to complete and has an elevation gain of 935 feet. The trail winds its way down from the Kohm Yah-mah-nee Visitor Center to cross West Sulphur Creek, and enter a nice stretch of high alpine meadow. About half way to Mill Creek Falls, the meadow gives way to the forest and a steady climb to Mill Creek Falls.
The 75 foot waterfall is nestled in some very difficult terrain, making photos nearly impossible except for from a couple of locations. The best spot for photos is at the vista point on the initial approach to Mill Creek Falls. The falls take place immediately after two creeks converge, and makes a nearly vertical drop to the rocks below.
There are nice wooden bridges across East Sulphur, and Bumpass Creeks before they converge to form Mill Creek Falls. The area around these bridges is easy to access, but potentially very dangerous, keep an eye of the kids.
