Nothing special about this park, but it worked for a one night stay. There isn't a sign for "San Antonio Bosque Park" off Hwy 380, instead turn at the second yellow cattle grate if you're coming from Interstate 25 (in addition to using the GPS coordinates). After you make this initial turn, the road splits (see photos) - take the higher road that's on the right. A short drive down this road will lead you to the entrance to the park (on your right).

It's a small park that wasn't developed with RVs in mind. But there are around 5 or so "sites" with picnic tables. Since we got in late, leaving early, and there wasn't anyone else around, we just pulled onto the side of one of the roads and called it a night. But, our rig and truck would've fit into one of the sites if necessary.

A lot of tree coverage here so it's not great for solar. There were also a bunch of cows roaming around freely, which meant watch out for cow patties!

Sign says San Antonio Bosque Park, which according to another site, is a series of riverine parks along the Rio Grande. Arrived at night and had trouble finding it, but would have been much easier in daylight, as it's visible from the road. Veer to the right as soon as you turn off the roadway, then there will be a right turn to go down a small hill into the campground. Our 26 ft rig was fine, and if we got back up the hill, you can too, but I'd recommend scouting it out. Larger rigs may have trouble maneuvering the campground, however. And some spots have lower clearance, though we were fine. Only saw one other person that was camping in a tent when we arrived and they were gone when we got up. Concrete picnic tables and fire rings, but there was a fire ban, though that didn't stop our neighbor. I'd go again, especially if it was on my route for an overnight.
