Del Rio has several parks, but most don't have a lot of activities.
The parks near Big Bend expect you to arrange your own entertainment, either in the local area or in the park. The drive along the Rio Grande River from Lajitas to Persidio is something I think everyone should do, and visit Fort Leaton State Park. But I would not recommend driving the RV on that route unless one has confidence in driving with a steep cliff on one side, a deep drop off on the other and a 12% grade.
You can look for the Marfa Lights. The MacDonald Observatory outside Fort Davis is wonderful. Lost Alaskan RV in Alpine is the best in the area, and many folks winter there. But it gets cold. We were hosts at Davis Mountains State Park outside Fort Davis in Nov, Dec and the first couple weeks on Jan.
Below freezing was common, we saw 17 three nights. Fort Davis is about 5,000 ft elevation, kind of cool at night in the summer. Lost Alaskan is at 4439 ft. It will be cold in the winter some.
We spent five weeks in Alamo in Jan and early Feb this winter.
The Encore park we stayed at, Alamo Palms, had a lot of activities. But we went to RC car races at another park, musical entertainment at four other parks, a health fare at another, and an RV dealer open house.
There are lots of things to do in the lower RGV, though many events will be at other parks.
