Fed by 4,000 vertical feet of runoff from Mt. Baldy, San Antonio Falls is one of So Cal’s tallest and most easily accessible year-round waterfalls. For many, it’s merely a stop on the way to Mt. Baldy, but for those who only have time for a short hike, it is an enjoyable destination in its own right. At more than 6,000 feet above sea level, it provides a perfect escape from summer heat in the Inland Empire. The hike is short enough that even those sensitive to altitude shouldn’t have a problem and while there may be snow during the winter, most of the route is on a paved service road, so weather is not likely to present a hazard.
From Manker Flats, follow the road uphill for 0.6 miles, taking in a few views down San Antonio Canyon on the way. You pass by a few driveways of private homes and under the shade of some tall pines before arriving at a sharp bend where the road continues toward Baldy Notch. Here, a use trail leads down to the base of San Antonio Falls, whose three tiers add up to an impressive 80 feet. Sadly, the waterfall’s easy access has led to trash and graffiti, although not as bad as Sapphire Falls or Bonita Falls. While some people just can’t have nice things, I can safely assume that readers of this blog will set a good example for other hikers and give this natural attraction the respect it deserves.
