From the KOA website: 
Travelers along the Santa Fe Trail used to arrive on horseback or by wagon to this lawless frontier town, where Billy the Kid once evaded a lynch mob. Today, travelers enjoy a more civilized reception at this KOA, tucked into the pinon- and juniper-scented foothills of the Sangre de Cristo Mountains. Wagon-wheel ruts, 900 historic buildings and the Fort Union National Monument highlight the areas past. Lakes and a national wildlife refuge showcase its natural wonders. At KOAs Café del Guapo, sample the green-chile Philly cheesesteak sandwiches and delicious steaks. Have your reunion or get-together in the new rec hall facility. Find Southwest and authentic Indian items in the campground store. Summertime fire truck rides at KOA make for a memorable visit. Rental unit/loft available (seasonal with breakfast). Limited services December 1 to March 1. Pool: May 15 - September 15. Max pull thru: 110 feet. Your hosts: Denny and Debby Matthews.

Las Vegas, New Mexico KOA

The Las Vegas, NM KOA was one of the prettiest KOA settings I have seen.  It is a stunning location, and the town of Las Vegas is charming.  The owners are were kind and helpful.  That being said, this property is tired and in need of some maintenance and love.  Our camping cabin needed chinking, I could see light through the logs.  Happily there was a heater for the cold rainy night.  The shower house was in great need of an update.  Breakfast was delicious, but really slow as there was only one kind gentleman doing the cooking and there were several groups to feed.  Some people cancelled their orders and left rather than staying to eat.

All that said, I would stay here again.  The people were kind, the cost was reasonable, and it still beats a tent in the rain when passing through on a long road trip.  And as I said at that start - it is beautiful.  My kids loved the playground.

This was our base of operations for a visit to Fort Union National Historic Site.

Top notch beauty, but needs some work

We stopped here for an overnighter and it was not the most aesthetic choice, but the town of Las Vegas is quite charming. The town has a great plaza and historic hotel where we had a pretty good meal. The sunsets and landscape in this part of New Mexico really take your breath away.

Campground close to a cool little town

We were hit by a blizzard driving through the I-25 pass from Santa Fe to Denver and had to take refuge in the KOA Las Vegas, NM for 2 nights. They quickly got us a space and allowed us to wait out the snow. Clean restrooms and showers, a shop in the grounds that serves breakfast. Hikes nearby. Very welcoming and friendly hosts.

Kozy, Clean and Accommodating

4/5/2021 Right off the highway. One of the nicer KOA's we have stayed at in the Southwest. True, the sites are close together which is typical at KOA's but this campground had lots of established trees which was nice (meaning shade). Many pull through sites. Full hookups. One of the unique things is they provide a full breakfast for a very nominal cost which got us going and out quickly. Pancakes, Eggs, Potatoes (with green chilis). It was really tasty. Despite being right off the highway it is quiet. Playground for kids. They are clearly working on improving and updating the sites. Fresh gravel. Looked very clean and well kept. The short dirt road was a little rough between the interstate and the entrance.  We were welcomed warmly and felt appreciated. We would stay here again.

A nicer KOA

This KOA campground is easily accessible off the highway. They had our reserved site all mapped out and ready for us on our arrival. They also provide a breakfast starting at 7:30 am for $6.40 per adult.

Very nice friendly, quiet campground 

One of the best RV parks we've ever stayed at. We'll maintained. Easy in &amp; out set up. Helpful, friendly staff. Beautiful scenic location surrounded by the Rockies. Only drawback is I-70 west of Denver.
