About San Antonio Falls
San Antonio Falls was a waterfall where it pays to time a visit for the peak snowmelt when Mt Baldy (formally known as Mt San Antonio) has accumulated snow during the Winter.
Luckily, Mt Baldy is quite visible from the Los Angeles basin (it’s the very prominent south-facing mountain when looking towards Pomona) so Mother Nature already provides clues as to when to time a visit.
And as you can see the photo above, when the timing is right, the waterfall puts on a show, and you can easily see why we included it on our Top 10 So Cal Waterfalls List.
So what is this timing, you may ask?
Timing San Antonio Falls
Our general rule of thumb is to observe whether Mt Baldy has had snow or not.
Usually in the Winters, the storms we get would produce snow in the mountains.
And if there has been an accumulation, it’s quite visible on the peak of Mt Baldy.
Of course with Climate Change, we now have to evaluate our Winters in terms of drought years versus wet years.
Therefore, it may be only certain years where it’s worth the effort to make it up to the slopes of Mt Baldy to see this waterfall despite the season.
In any case, when the seasons change and the weather warms up (typically in the Spring), that would be when the creek responsible for feeding the waterfall would contain the volume it would need to put on a show.
That said, there are other nuances with timing a visit to San Antonio Falls in addition to the waterfall’s flow.
For example, we’ve come to the falls when there was still enough snow clinging to its neighboring slopes.
As a result, San Antonio Falls blended in with the snow and was harder to see (let alone photograph).
In addition, with the presence of snow, the footing was a bit trickier and more slippery (due to ice) so we really had watch our steps.
On the other hand, we also came when most of the snow around the waterfall had melted.
This allowed us to see the San Antonio Falls’ uppermost tiers, but it also meant that the flow was waning.
When there’s good flow, the falls may feature an intriguing waterwheel (where the water was thrown up before dropping back down), which further added to its scenic allure.
However, when there’s less flow, the waterwheel would be either non-existent or not as pronounced.
Accessing San Antonio Falls
The hike to San Antonio Falls was really more of a short walk on the paved Falls Road (though when Julie and I were first here back in 2005, Falls Road was not paved).
This road deviated from Baldy Road at Manker Flats (see directions below).
The slightly uphill hike was very easy for the family since it was pretty much a walk on the road as long as we weren’t walking on snow or ice.
During the walk, we even had a nice glimpse of the LA Basin looking downslope near where the road made a sharp turn.
We also noticed some driveways or local residences, which might have been the reason why Falls Road had been improved over the years.
After about 3/4-mile, we arrived at the lookout for San Antonio Falls, which would be situated right at a hairpin bend on Falls Road typically with a railing or barricade from which you get a pretty good view.
It was from this vantage point that we could appreciate its three main drops which might be on the order of 100-150ft tall (even though Ann Marie Brown
We had also noticed there were a few more tiers above and below this main section so it’s conceivable that we could’ve easily underestimated the overall height of the waterfall.
That said, the taller slopes made the falls appear smaller or even more invisible by comparison, especially when there’s snow.
Scrambling to the base of San Antonio Falls
Beyond the overlook at the end of the hairpin turn on Falls Road, there was a narrow path that led right to the base of San Antonio Falls.
A short distance from the overlook at the Falls Road hairpin, there was a pretty well-worn section of the track that definitely required us to wear shoes with decent grip.
A slip and fall into that ravine that the slope faced would certainly be cause for injury.
Even if you slid down there uninjured, it looked like it would be a difficult scramble back up.
Therefore, I can see why more than a few people wouldn’t want to continue from the overlook to the base of the falls (at least for our first several visits).
That said, in recent years, this place had become so popular that the erosion-prone part of the trail was re-routed below the sketchy ledge-clinging part.
This was something that we noticed on our April 2024 visit, and this re-routing made this once-sketchy section significantly easier than in the past.
Anyways, Falls Road continued going up the slope apparently towards the lifts at the Baldy Summit, but we’ve never hiked past the waterfall so we can’t comment more on it.
Thus, the round trip distance of this hike was on the order of 1.5 miles and generally 90 minutes to 2 hours was more than enough time for us to enjoy both the hike and the falls.
Authorities
San Antonio Falls resides in the San Bernardino National Forest near Mt Baldy in San Bernardino County, California. It is administered by the USDA Forest Service. For information or inquiries about the area as well as current conditions, visit their website or Facebook page.
To get to San Antonio Falls, there are a few ways to go after getting onto the I-210 East towards the Claremont area (34 miles east of downtown Los Angeles).
The Most Direct Route
The most straightforward way to get to the falls from the I-210 East Freeway would be to exit at Base Line Road..
Once on the traffic light, we’d then turn left onto Base Line Road before turning right at the next light onto Padua Road.
Next, we’d follow Padua Road through what looked like a pretty new suburban neighborhood until eventually reaching an intersection with Mt Baldy Road.
Then, we’d turn right onto Mt Baldy Road and take it roughly 9 miles or so climbing along the winding mountainous roads through Baldy Village (note to keep left at the Ice House Canyon turnoff to remain on Mt Baldy Road shortly after the village).
Eventually, we’d reach the Falls Road entrance just beyond the Manker Flat Campground.
There’s usually lots of vehicles parked along the divided Mt Baldy Road on the downslope side around the Falls Road so you can’t miss it.
If we didn’t have a Forest Service Pass in hand to display in our parked vehicle, we could buy one from one of the handful of outfitters and shops in Baldy Village.
A Slightly Different Driving Route as described in the Ann Marie Brown book
On one of our recent visits, we followed Ann Marie Brown’s directions as described in her book
She had us exiting the I-210 Freeway at Mountain Ave and taking it north for 4.3 miles.
Shortly after a hairpin turn by Lower San Antonio station, we then had to turn sharply right at a blind turn onto Mt Baldy Road.
From there, we then continued climbing up the mountain for the next 9 miles to Manker Flat Campground and ultimately the trailhead for San Antonio Falls shortly thereafter.
Car Maintenance and Mountain Roads
Speaking of climbing, I want to mention that for steep mountain roads like this (especially on the hairpins and grades beyond Baldy Village), we had to be honest with ourselves about the condition of our car.
We had one incident with our Corolla with 230k miles on it where we managed to make it, but we did have a bit of a scare.
That was because we noticed some steam or smoke protruding from the hood (despite the fact that the car made no indication of overheating or abnormally high engine temperatures).
On a separate visit, the automatic transmission fluid on my parents’ SUV overheated due to negligence of not having that fluid flushed prior to making our visit.
Luckily, the issue solved itself when we parked the car and returned to it some 90 minutes later after doing the hike.
So just keep this in mind if you have an old car, because it’s not exactly an ideal place to have a break down.
For geographical context, Mt Baldy is 14 miles (over 30 minutes drive) north of Ontario, 43 miles (about 1 hour drive) northwest of Riverside, 47 miles (about 90 minutes drive depending on traffic) northeast of downtown Los Angeles, and 49 miles (about 90 minutes drive depending on traffic) north of Irvine.

It was so steep it was like running on the moon. One step, then sink into the gravel, then… ...Read MoreNearest Waterfalls
