Our favorite RV park we went to for years is
Fun Valley Family RV Resort. Resort in this case is a little misleading. It is not a high end/high dollar place. Resort refers more to what it has to offer. It is family oriented, but also has a lot of us old timers. We would take our 5er and our kids and grandkids stayed in cabins. It is large and strung out along a mile of the South Fork of the Rio Grand River in southern Colorado near Wolf Creek Pass. They have a restaurant, grocery, laundry, about 15 stocked trout ponds, paddleboats, tube floating on the river, miniature golf, real golf outings to nearby courses, horseback rides, street dances, C&W dancing in the barn, July 4th parades, etc. And short drive to Pagosa Springs, Creede, Great Sand Dunes, Cumbres & Toltec scenic steam railroad, etc. Or rent a jeep to go back country touring.
But it is a very active place. Some don't like it because there is a lot of activity, people out walking or bike riding, "train" taking people for rides around the park. It is a very old park and some of the sites are arranged somewhat haphazardly due to smaller size RVs in the old days.
We loved the place and had great time. Tons of memories of family vacations together.
Now for the disclaimer. We have not been since 2014 due to reduced travel. And the place sold about 5 years ago. New owners have done a lot of upgrades, but have also raised the prices over the very low prices we paid years ago. We have wanted to go back for years, but just have not been able to.
