Never Stayed in Durango, but here's what I have on that area.
Southern Colorado & Northern New Mexico & Western Colorado as well.
For ATV trails, Telluride might be a neat place to check out. CO 145 off US 160 (West of Durango) will take one to Telluride. The Lizard Head Pass at 10,222' before getting to Telluride should have some trails to ride in that area. We had mountain bikes with us & in riding along a forest road to the east of the Pass, we found Trout Lake & road by it as well. We were able to drive our van on the roads as well. ATVs could explore them very well. There is a "Jeep" Trail or Road going up from Telluride into very high country as well.

DittoI've never ridden Durango Steam Train, but have ridden the one in Chama Area. A Neat Ride.
A little on the
Chama Area.
We enjoyed visits in the
Trujillo Meadows Area by Cumbres Pass....the CG seems to be closed this summer, but perhaps the Forest area isn't & the Trujillo Meadows Reservoir. I remember a long ridge leading off not far from the entrance. Might be a nice place to explore with ATVs. Should be cool up there as well.
Chama Basin - about 40 miles of trails. The parking area is about 10 minutes north of Chama, NM (near the border). Drive north from Chama 4-5 miles and turn left (west) at Lobo Lodge. Drive 5-6 miles into a small camp area (with toilets) right next to the Chama River. This is a nice place with excellent views and it's easy to get to. If you're going to fish, you need a CO license.
Cumbres Pass to La Manga Pass - The mountains north of Chama, NM are excellent for camping, scenery, and casual dirt road riding and some trail riding. Chama is about 8 miles south of the NM/CO border; the mountains are in Colorado, starting at the border. There is a campground at Trujillo Meadows Reservoir. There's a good supermarket in Chama for supplies.
Some of the same but
Expanded on Chama Area.
