San Antonio Creek rises from the melting snows of Mt. San Antonio (also known by southland residents as Mt. Baldy). Much of the watershed is an area of high ecological significance. The creek tumbles down through a steep alpine canyon with spectacular views. It then drops through a series of four waterfalls, culminating in 80-foot high San Antonio Falls. The magnificent lower falls is a relatively easy 1.4-mile roundtrip walk from the Manker Flat parking area. This walk provides a fine destination for a family picnic. One mile of the creek upstream of the lower falls is proposed by Friends of the River for Wild River designation and part of it is located in a proposed addition to the Sheep Mountain Wilderness. The remaining 3 miles of the creek downstream of the falls is proposed as a Recreational river.

Visit San Antonio Creek!
The San Antonio Creek Falls Trail is only a short hike from the parking lot at Manker Flat. Visitors are rewards with outstanding views of the 80 foot-high San Antonio Falls. The short road and trail route is easily accessible by most people, but with one narrow and eroded section of trail.

How To Get There
From Interstate 210 in the City of Upland, take the Mountain Avenue exit and drive north 9.5 miles to where it dead-ends in Mt. Baldy Road. Turn right on Mt. Baldy Road and drive 5.25 miles north through Baldy Village to the parking area at Manker Flat. The Mt. Baldy Road heads off to the left of the parking area but is gated and motorized access is limited to local cabin owners and the Mt. Baldy Ski Resort. Walk .6 miles up the paved road to the first switch back. Magnificent San Antonio Falls can be seen from this point. A short dirt trail drops down from the road switchback to the base of the falls. Care should be taken as erosion has narrowed the dirt trail in places. You will need to purchase a $5 Adventure Pass to park at Manker Flat. The pass is available at the Forest Service visitor center in Baldy Village.
