Date of Adventure: October 27, 2025
Last Monday, October 27th., I decided to head out into the Jemez Mountains and look for some alternate trails to hike into San Antonio Hot springs. The main road into the hot springs, Forest Road 376, gets closed right off the tarmac in the winter after it starts to snow. The distance from the snow gate to the Hot springs is about 5 mi along the Forest Service Road. I've done it on skis, maybe 8 or 10 times. Including, at least twice, when we dawdled too long in the springs and had to ski out partway in the dark. But this year I'm trying to figure out reasonable routes to snowshoe into the Hot Springs and 5 mi on snowshoes seems kind of excessive to me right now.
It's really interesting to drive through White Rock and past some of the Los Alamos sites. Reminded me a lot of some of the times when I was working at Los Alamos. And the drive through the Jemez is always kind of fun and interesting to me. In some of the high areas there was snow in the very shady places.
This picture shows a little bit of it. But there were places where there was a lot more than this and it's been three or maybe five days since the last heavy rain so these shady places have been pretty cold.
Driving through the Valles Caldera has always been kind of an experience for me. It's a really spectacular valley with an interesting history. It was a private cattle ranch, call the Baca Cattle Company dating back to the 1870s when the Baca Family acquired it. It went through a couple of owners until 2000 when the federal government traded the land with the owner for some property in Colorado and it became a national preserve. When I first started working at Los Alamos it was still a private cattle ranch. People would cross country ski across the back part of the valley. It was technically trespassing and they always had to be little careful not to get caught. It is possible to hike or ski or even snowshoe from the top of Pajarito Ski Hill to San Antonio Hot springs. I never did it myself but I've known several people who did. I wonder if it is still a common XC ski excursion or if it has lost it’s allure now that it is legal to do it.
In midsummer the Valle can be really green but this time of year the grass has mostly died. It still is a beautiful subdued brown color. It's a little bit hard to pick out but in this picture towards the left there's a small dome that was an eruption after the main volcano exploded. It I called Cerro la Jarra. Right at the base of that dome is the visitor center.
The drive takes you through about three different forest fire areas. This is a pretty crappy picture but it shows what the hillside's look like even 8 or 10 years after the last forest fire.
Aside from the main forest road into the Hot springs and the long hike from Pajaritoo Ski Hill, I think there are two other main trails that will get you to the hot springs. One of them comes down from Thompson ridge. Many, many years ago I skied that route with a few friends and my recollection is that the final descent into the Hot springs is pretty gnarly and steep. But I thought I would check it out anyway. There are no big secrets here so I’ll tell the routes. To get there you take Forest Road 106 off of New Mexico route 4. If you're really interested the trailhead for the hike is at 35.9147, - 106.6397. It's a pretty hike at least for the mile that I hiked but it's all in a pine forest. Here's what it looked like at the very beginning .
And Forest Road 106 is pretty steep and rutted. The rutting didn't bother me much but I'm afraid that the steepness could be a real problem in the snow. So I decided to go try and check out the second trail that I knew about. That trail starts on the opposite side of San Antonio Canyon so you have to drive New Mexico route 126 out of La Cueva. I don’t know how many “La Cuevas” there are in New Mexico but this isn’t the primary one if you Google search.
To get to the trailhead for the second trail you drive along 126 and pass the main Forest Road (376) into San Antonio Hot springs. This photo shows where the Forest Road leaves the tarmac and the snow gate that gets closed once there's a bunch of snow on the dirt road.
About 2 mi past Forest Road 376, sort of at the top of the hill, you come across Forest Road 144 and that's the route into the next trailhead. It's about 7 mi from the tarmac to the trailhead and it's a slightly rutted dirt road but not very hilly. There are no snow gates and it looks like there's no problem driving in here. The only issue in the winter time would be how deep the snow is and whether anyone had driven it and packed it down and made it easier to drive. The coordinates for the trailhead are: 35.9610, - 106.6363. this trail is actually a semi-abandoned road. The beginning, a little over a half a mile, is somewhat downhill but would be easy on snowshoes or cross-country skis.
At the bottom of the downhill there's a beautiful meadow with San Antonio Creek running through it.
From there I just walked the old abandoned road that runs parallel to San Antonio Creek more or less south southwest.
It's about two and a quarter miles from the trailhead to the bridge across San Antonio Creek that leads up to the Hot springs. I didn't hike the whole distance because I ran into base spot where a spring had made the trail really nasty and muddy so I turned around.
This was a pretty good afternoon hike and would be an excellent way to get into San Antonio Hot springs in the winter time. If Forest Road 144 is passable!! My guess is it would be fairly easy with good tires and four-wheel drive.
There's even more to do in the area. Here's a picture of the old Jemez Springs Bathhouse.
As many times as I've been through Jemez Springs, I've never visited the old bathhouse and it would really be an interesting stop. Mostly to see what the old time place looked like.
And then there's always Los Ojos Restaurant and Saloon. This used to be one of my favorite places to get a green chili cheeseburger when driving through or hiking the hot springs around Jemez. But somehow I think it's changed ownership and although it's still kind of funky it's lost some of the funkiness that it used to have.
That's the fall exploration, looking for winter ways to get into San Antonio Hot springs after the snow after the snows have fallen.
