A must see!
This is a great location. Getting there you are driving through the middle of NM ranch land and slowly the topography starts to change as you get closer, and it is very cool!
The road down the canyon is about 2 miles and any stock SUV, Subaru or the same can make it when it's dry. But, if it's wet be careful, the mud is super slippery….just take your time! You could probably even do it in a sedan as long as you aren't too low to the ground.
If you read other reviews or see videos on YouTube you may hear that trailers are not allowed on the road down. As of April 2018 the warning at the top say not recommended. I was in a Ford Expedition with an 8' popup trailer (probably 11' with the tongue) and it was no problem. I wouldn't take a 5th wheel or a huge camper down there, but smaller trailers are ok. The sharpest turns are near the top.
The campground is very nice, the 12 spots are spread out, two nice pit latrines, tables, fire pits, and charcoal grill stands. THERE IS NO WATER except for the river, and no trash service, so pack it out!.
The valley is gorgeous and you can see the ruins from the old homestead….be sure to stop and read the info signs on the way down, it's a very neat story
I went at the end of April, the days were great and the nights were cool, I can see how it would get very hot in the summer. There is some shade but be sure to bring an easy up or something.
The first river crossing is a concrete bottom, the second is river bottom but not too deep, the third one is much more rough and very wide, use common sense. Lots of opportunity for hiking and biking.
Hunting is allowed so don't be surprised if you hear shots during hunting season. We saw several turkeys and deer. The signs say bears and cougars are in the area as well.
I think there are fish in the rive but we didn't get any. There is a lot of 'grass' in the water to be prepared to get snagged.
Take a good map with you and explore some off the roads in the grasslands area that take you to the rim of the canyon, it's a great view.
I drove from Denver, about 6 hours, and it was worth the drive. Highly recommended.
There is also a campsite on the rim if you don't want to venture down, and they have some horse paddocks you can use.
