FUN VALLEY FAMILY RESORT. If this isn't the place you were thinking of, there is an excellent US Forest Service campground on Wolf Creek Pass called Big Meadows that you may have seen as it sits just over a mile off Hwy. 160 and is only about 8 miles from the summit of the pass.
Unfortunately, Big Meadows is closed as the Forest Service completely rebuilds this campground. Phase I is scheduled for completion this fall and Phase II will begin next summer, most likely in June depending on our snowfall this winter. Phase II construction drawings can be found here;

Good luck with your trip!
